3月 16th, 2025 News

Polyurethane TPE anti-yellowing agent: a secret weapon for durability of sports facilities

In modern society, sports facilities are not only an important place for fitness and entertainment, but also a symbol of the city’s image and quality of life. However, these facilities often face various environmental challenges such as ultraviolet radiation, extreme temperature changes, and chemical erosion, which can accelerate the aging of materials and cause their appearance and performance to decline rapidly. Among them, the yellowing problem is particularly prominent. It not only affects the aesthetics of the facilities, but also may weaken the mechanical properties of the materials and shorten their service life.

Polyurethane thermoplastic elastomers (TPEs) have attracted much attention due to their unique physical properties and widespread industrial applications. However, when exposed to natural environments for a long time, this material is prone to yellowing, thus limiting its use in areas of high outdoor demand. To solve this problem, scientists have developed anti-yellowing agents specifically targeted at polyurethane TPE. This type of additive effectively delays the yellowing rate of the material by inhibiting photooxidation reactions and other degradation processes, thereby significantly improving the durability and visual effect of sports facilities.

This article will deeply explore the key role of polyurethane TPE anti-yellowing agents in improving the durability of sports facilities. We will not only introduce in detail the working principle of the anti-yellowing agent and its specific impact on material properties, but also provide detailed product parameters and domestic and foreign research data support. In addition, the article will combine actual case analysis to show how to optimize the design and maintenance strategies of sports facilities through the rational selection and use of anti-yellowing agents. Next, please follow our steps and explore the mystery behind this science together!

1. Basic knowledge of polyurethane TPE anti-yellowing agent

(I) What is polyurethane TPE?

Polyurethane thermoplastic elastomer (TPE) is a new polymer material that combines rubber elasticity and plastic processing properties. It consists of alternate hard and soft segments, with excellent wear resistance, flexibility and tear resistance. It is widely used in sports soles, track surface coatings, fitness equipment shells, and other sports facilities that require high strength and durability.

However, although polyurethane TPE itself has excellent performance, it is susceptible to external factors during long-term use, especially the effects of ultraviolet rays and oxygen, which will cause molecular chain breakage or crosslinking, which will lead to yellowing. This color change not only destroys the aesthetics of the product, but may also lead to a gradual degradation of material properties, ultimately affecting the overall life of the facility.

(II) Mechanism of action of anti-yellowing agent

In order to overcome this defect of polyurethane TPE, researchers have designed a special additive – anti-yellowing agent. This type of substance mainly works in the following ways:

  1. AbsorptionUltraviolet rays
    The UV absorbing components in the anti-yellowing agent can capture and convert high-energy ultraviolet rays, converting them into lower-energy thermal energy and releasing them, thereby avoiding the direct effect of ultraviolet rays on the polyurethane molecular chains and reducing the generation of free radicals.

  2. Capture free radicals
    Free radicals are one of the core factors that cause material aging. Anti-yellowing agents are able to actively capture these unstable molecules, preventing them from further attacking other polymer chains, thereby delaying the degradation process.

  3. Stable chemical structure
    Certain anti-yellowing agents can also enhance the antioxidant capacity of polyurethane TPE by adjusting the chemical environment inside the material, making it more tolerant of long-term use under harsh conditions.

(III) Classification of anti-yellowing agents

According to the functional characteristics and mechanism of action, anti-yellowing agents can be roughly divided into the following categories:

Category Description Common Representatives
Ultraviolet absorber Absorb UV rays and reduce the risk of photooxidation Benzotriazoles, benzophenones
Light Stabilizer Stop the occurrence of photochemical reactions Hardened amines (HALS)
Antioxidants Neutralize free radicals and slow down the oxidation process Stealed phenols and phosphites
Comprehensive Anti-yellowing Agent Combining multiple functions, providing comprehensive protection Complex Products

Each type of anti-yellowing agent has its unique advantages and scope of application. The specific choice needs to be adjusted according to the needs of the actual application scenario.

2. Detailed explanation of the product parameters of polyurethane TPE anti-yellowing agent

In practical applications, understanding the various technical parameters of anti-yellowing agents is crucial to ensure their effectiveness. The following are the main performance indicators and reference values ??of several common anti-yellowing agents:

parameter name Unit Test Method Reference value range Remarks
Density g/cm³ ASTM D792 1.05-1.20 Influence the amount of addition and uniform distribution
Thermal Stability ? ISO 3146 >280 Remain active under high temperature environment
Migration resistance % GB/T 24135 <1.0 Prevent contaminated surfaces from the material
Anti-yellowing index – ASTM D2244 ?5 The lower the value, the better
Compatibility – Laboratory Assessment Good Ensure full integration with the substrate

It should be noted that different brands and models of anti-yellowing agents may have slight differences, so you should carefully review the product instructions when purchasing and make a good choice based on laboratory test results.

III. Effect of polyurethane TPE anti-yellowing agent on the durability of sports facilities

(I) Theoretical basis and experimental verification

Study shows that after one year of exposure to untreated polyurethane TPE in outdoor conditions, its yellow index usually increases by about 10-15 units, while the tensile strength drops by more than 20%. After adding an appropriate amount of anti-yellowing agent, the yellow index increase of the same material during the same time period can be controlled within 3 units, and the mechanical properties remain basically unchanged. This significant improvement is attributed to the effective protection of the material’s internal structure by the anti-yellowing agent.

For example, an internationally renowned research team has compared the weather resistance of two runway surface coating materials: one contains only ordinary antioxidants, and the other adds a high-performance comprehensive anti-yellowing agent. The results show that the latter has always maintained a good appearance in three consecutive years of outdoor testing, while the former has obvious fading and cracking.

(II) Analysis of specific application cases

1. Long-lasting wear resistance of sports soles

As an important equipment for athletes’ daily training, sports soles directly affect the user’s performance. Traditional polyurethane TPE soles are prone to yellowing or even opening when frequently rubbed and exposed to sunlight.cracking situation. By introducing anti-yellowing agents, modern sole materials can greatly improve anti-aging capabilities and extend service life while ensuring light weight.

2. Anti-corrosion performance of fitness equipment shells

The equipment shells in the gym often lose their luster due to the erosion of chemicals such as sweat and detergents. The shell made of polyurethane TPE material containing high-efficiency anti-yellowing agent can not only resist these external threats, but also maintain a long-lasting appearance, bringing a better experience to users.

3. Anti-slip and anti-fouling performance of outdoor basketball court floor

The outdoor basketball court must have extremely high stability and easy cleaning in the face of wear caused by rain erosion, dust accumulation and vigorous exercise. The polyurethane TPE coating modified with anti-yellowing agent can not only resist yellowing caused by ultraviolet rays, but also effectively prevent oil stains from penetration, so that the court always maintains bright colors and good grip.

IV. Domestic and foreign literature reviews and new research results

In recent years, many breakthroughs have been made in the research on polyurethane TPE anti-yellowing agents. The following lists some representative achievements for readers’ reference:

  1. American scholar Smith et al. (2020) proposed a new anti-yellowing agent formula based on nanotechnology. This formula significantly improves its dispersion and long-term effectiveness by uniformly dispersing the ultraviolet absorber on the surface of nanoparticles. Experiments show that this new method can improve the anti-yellowing ability of polyurethane TPE by nearly 40%.

  2. The Research Group of Ruhr University in Germany (2021) found that by optimizing the interaction between the anti-yellowing agent and the substrate, the initial yellowing tendency of the material can be further reduced. They proposed a “pre-crosslinking” process, so that the anti-yellowing agent has formed a stable network structure during the material forming stage, thereby better exerting its functions.

  3. Institute of Chemistry, Chinese Academy of Sciences (2022) has carried out a large-scale outdoor weather resistance testing project, systematically evaluating the actual performance of a variety of commercial anti-yellowing agents. The results show that some compound products are better than single-component additives in comprehensive performance, and are especially suitable for long-term applications in complex environments.

V. Summary and Outlook

The emergence of polyurethane TPE anti-yellowing agent provides a powerful solution to improve the durability of sports facilities. Whether it is sports soles, fitness equipment or outdoor venues, you can achieve a longer service life and better visual effect by scientifically selecting appropriate anti-yellowing agents. In the future, with the continuous advancement of new material technology and processing technology, I believe that the application scope of anti-yellowing agents will be further expanded.Large, its performance will be more complete.

After, let us summarize the core idea of ??this article in one sentence: polyurethane TPE anti-yellowing agent is like an invisible protective umbrella, sheltering sports facilities from the wind and rain, so that they can still shine in the baptism of time!

The innovative use of polyurethane TPE anti-yellowing agent in agricultural equipment

3月 16th, 2025 News

Polyurethane TPE anti-yellowing agent: innovative application in agricultural equipment

1. Introduction: From “the hero behind the scenes” to “agricultural pioneer”

In the wave of agricultural modernization, various mechanical equipment is like the “steel warriors” in the fields, protecting the sowing, growth and harvest of crops. However, behind the efficient operation of these devices, there is a material that is often overlooked – it is polyurethane thermoplastic elastomer (TPE). As an important part of modern industry, polyurethane TPE has become one of the indispensable materials in the field of agricultural equipment manufacturing with its excellent performance. However, as the equipment is exposed to natural environments such as sunlight and rainwater for a long time, TPE materials are prone to oxidation and degradation, causing the surface color to gradually turn yellow or even age and crack, seriously affecting its appearance and service life. Therefore, how to effectively prevent this “yellow change” phenomenon has become a technical problem that the industry needs to solve urgently.

It is in this context that polyurethane TPE anti-yellowing agents emerged. This new additive can not only significantly delay the aging rate of TPE materials, but also maintain its original flexibility and mechanical strength, thereby extending the service life of agricultural equipment. More importantly, its emergence offers more possibilities for the design and manufacturing of agricultural equipment. For example, through synergistic effects with anti-ultraviolet stabilizers, anti-yellowing agents can help the equipment maintain good performance in high temperature and high humidity environments; through the combination with flame retardants, the safety of the equipment can be further improved. It can be said that polyurethane TPE anti-yellowing agent is not only a technological breakthrough in the field of materials science, but also a key force in promoting the development of agricultural equipment towards high performance and long life.

This article will conduct in-depth discussions on polyurethane TPE anti-yellowing agent, covering its basic principles, product parameters, application scenarios, and domestic and foreign research progress. At the same time, we will also demonstrate the practical application effect of this innovative material in agricultural equipment through specific case analysis. This is a rare feast of knowledge for materials scientists and agricultural engineers.

2. Basic principles of polyurethane TPE anti-yellowing agent

To understand the mechanism of action of polyurethane TPE anti-yellowing agent, you first need to understand why TPE materials turn yellow. Simply put, TPE is a block copolymer composed of hard segments and soft segments, where the hard segment is mainly responsible for providing the strength and rigidity of the material, while the soft segment imparts flexibility and elasticity. However, when TPE is exposed to external environmental factors such as ultraviolet light, oxygen or high temperature, a series of complex chemical reactions will occur in its molecular structure, which will eventually lead to deterioration in material performance and changes in appearance.

(I) Causes and processes of yellowing

  1. Photooxidation reaction
    Ultraviolet light is one of the main reasons for yellowing of TPE. When ultraviolet rays hit the surface of TPE, it will stimulateUnsaturated bonds in the material form free radicals. These free radicals then react with oxygen in the air to produce peroxides and other oxidation products, which gradually turn the material yellow.

  2. Thermal oxygen aging
    Under high temperature conditions, the polymer chains in TPE may be broken or cross-linked, further exacerbating the aging process of the material. Especially in agricultural equipment, TPE is more susceptible to the threat of thermal oxygen aging due to long-term operation and frequent contact with soil, moisture and other factors.

  3. Impurity Effect
    If the TPE raw material contains trace amounts of metal ions or other catalyst residues, it may also accelerate its yellowing process. This is because these impurities promote the formation of free radicals, thereby speeding up the oxidation reaction.

(II) Mechanism of action of anti-yellowing agent

To combat the above problems, polyurethane TPE anti-yellowing agents adopt various strategies to inhibit the occurrence of yellowing:

  1. Free Radical Capture
    One of the core functions of anti-yellowing agents is to capture and neutralize free radicals, preventing them from continuing to participate in the oxidation reaction. For example, phenolic antioxidants can convert free radicals into stable compounds by providing hydrogen atoms, thereby terminating the chain reaction.

  2. Ultraviolet absorption
    Some anti-yellowing agents also have ultraviolet absorption capacity, which can convert the energy of ultraviolet light into harmless heat and release it, avoiding its direct effect on TPE materials. This function is similar to putting a layer of “sun protection clothes” on TPE.

  3. Metal ion passivation
    In response to the yellowing problem caused by impurities, anti-yellowing agents can bind to metal ions through chelation to reduce their catalytic activity, thereby slowing down the speed of the oxidation reaction.

  4. Synergy Effect
    It is worth mentioning that many anti-yellowing agents do not function alone, but form synergistic effects with other additives (such as light stabilizers, thermal stabilizers, etc.) to jointly improve the overall weather resistance of TPE.

(III) Types and characteristics of typical anti-yellowing agents

Depending on the chemical structure and function, polyurethane TPE anti-yellowing agents can be divided into the following categories:

Category Main Ingredients Functional Features Scope of application
Phenol antioxidants Tert-butylphenol, bisphenol A Catch free radicals and delay oxidation reaction; good thermal stability Agricultural equipment shells in high temperature environments
Amine antioxidants P-phenylenediamine, aromatic amine Provides stronger free radical scavenging ability; may have certain toxicity Special purpose seals and wear-resistant components
Phosphate anti-yellowing agent Triphenylphosphite, trimethylphosphate It has both oxidation resistance and flame retardant properties; improves material processing fluidity Agricultural Vehicle Interior Parts and Safety Protection Devices
Organic nickel compound Nickel salts, nickel chelates Inhibit the formation of carbonyl compounds and reduce yellowing; suitable for light or transparent products Agricultural Machinery Dashboard and Decorative Panel
Ultraviolet absorber Benzotriazole, salicylate Absorbs ultraviolet energy to protect the material from photoaging Farm tools and covering films for long-term outdoor use

By reasonably selecting and matching these anti-yellowing agents, TPE formulas suitable for different agricultural equipment can be customized according to specific needs, thereby achieving good anti-yellowing effect.

3. Detailed explanation of product parameters of polyurethane TPE anti-yellowing agent

As a functional additive, the performance parameters of polyurethane TPE anti-yellowing agent directly determine their performance in practical applications. The following are several key indicators and their significance:

(I) Addition amount

The amount of the anti-yellowing agent added is usually expressed as mass percentage, generally between 0.1% and 2%. Too low addition may lead to insufficient anti-yellowing effect, while too high may affect other performance of TPE. For example, for some agricultural equipment parts that require high transparency, the amount of anti-yellowing agent added needs to be strictly controlled to avoid increasing haze or decreasing light transmittance.

Additional range (wt%) Applicable scenarios Precautions
0.1%-0.5% Light color or transparent products Ensure uniform dispersion and avoid excessive local concentration
0.5%-1.0% General-purpose agricultural equipment shell Adjust the ratio according to the specific formula
1.0%-2.0% High-strength components under extreme conditions Extra test for compatibility may be required

(II) Temperature resistance

The temperature resistance of the anti-yellowing agent refers to its ability to maintain effectiveness under high temperature environments. Generally speaking, high-quality anti-yellowing agents can operate stably in the range of 100°C to 200°C. However, if agricultural equipment is often in higher temperature working environments, a specially designed anti-yellowing agent needs to be selected.

Temperature range (?) Recommended anti-yellowing agent types Application Examples
?100 Phenol antioxidants Light tools in agricultural greenhouses
100-150 Phosphate anti-yellowing agent Rubber seal strips for agricultural tractors
?150 Organic nickel compound High-speed rotating agricultural machinery transmission components

(III) Mobility

Mobility refers to the tendency of anti-yellowing agents to diffuse outward from the TPE matrix. If the mobility is too high, the anti-yellowing agent may gradually lose during use, resulting in a weakening of the anti-yellowing effect. Therefore, when designing agricultural equipment, low mobility anti-yellowing agents should be preferred.

Migration Level Test Method Result Evaluation
Low ASTM D6978 Dissolution Test ?0.1mg/cm², suitable for long-term use
in ISO 105-B02 sweat stain test 0.1-0.5mg/cm², required regular maintenance
High Custom simulation experiment >0.5mg/cm², only forShort-term application

(IV) Environmental protection

As the global focus on environmental protection is increasing, the environmental protection of anti-yellowing agents has also become one of the important criteria for measuring their advantages and disadvantages. Ideal anti-yellowing agents should have good biodegradability and low toxicity to reduce the impact on the ecological environment.

Environmental Certification Complied with standards Example Product
REACH EU Chemical Registration, Evaluation and Authorization Regulations BASF Irganox Series Anti-Yeling Agent
RoHS Suppression of hazardous substances directive Clariant Hostanox Series Anti-Yeling Agent
FDA US Food and Drug Administration Standards DuPont Zerust series anti-yellowing agent

IV. Application scenarios of polyurethane TPE anti-yellowing agent in agricultural equipment

The application range of polyurethane TPE anti-yellowing agent is very wide, covering almost all types of agricultural equipment. Here are some typical examples:

(I) Agricultural Machinery Case

The shell of agricultural machinery not only needs to withstand the erosion of the external environment, but also maintain a good appearance. By adding an appropriate amount of anti-yellowing agent, the shell can still maintain a bright color and smooth surface after long-term use. For example, a tractor cab ceiling made of TPE material, after adding 0.5% phenolic antioxidants, the yellow index change value is only 2.3, far lower than the 15.6 of the untreated sample after being exposed to the sun for a year.

(II) Irrigation system accessories

In modern irrigation systems such as drip irrigation and sprinkler irrigation, TPE materials are often used to make key components such as hose joints and valve seals. These components are immersed in water for a long time and are susceptible to microbial contamination and chemical corrosion. By introducing anti-yellowing agents, it not only extends its service life, but also ensures smooth water flow. Studies have shown that TPE hoses containing phosphate anti-yellowing agents have improved hydrolysis resistance by about 40%, and there are no obvious signs of aging after two consecutive years of operation.

(III) Agricultural film

Agricultural films are an important tool to protect crops from bad weather. However, traditional polyethylene films tend to become brittle under ultraviolet raysYellow seriously affects its light transmittance and thermal insulation effect. By combining TPE with UV absorbers and anti-yellowing agents, a new composite film can be developed, with a service life of nearly three times longer than that of ordinary films, while also better meeting the needs of modern agricultural production.

5. Domestic and foreign research progress and future prospects

In recent years, research on polyurethane TPE anti-yellowing agents has achieved many breakthrough results. For example, Bayer, Germany, has developed an anti-yellowing agent based on nanotechnology, which has better dispersion and stability than traditional products; Dow Chemical in the United States has launched a multifunctional composite anti-yellowing agent, which can achieve various functions such as antioxidant, anti-ultraviolet and flame retardant in the same formula.

However, despite the continuous advancement of technology, the research and development of polyurethane TPE anti-yellowing agents still faces many challenges. First of all, there is a cost issue. The price of high-performance anti-yellowing agents is often higher, which limits its promotion in the low-end market; secondly, there is a problem of standardization. There is currently a lack of a unified testing method and evaluation system, which makes it difficult for products from different manufacturers to be compared horizontally.

Looking forward, with the introduction of emerging technologies such as artificial intelligence and big data, the research and development of anti-yellowing agents will be more accurate and efficient. In addition, the popularization of green chemistry concepts will also prompt the industry to develop in a more environmentally friendly direction. We have reason to believe that in the near future, polyurethane TPE anti-yellowing agents will play a greater role in the field of agricultural equipment and create more value for mankind.

6. Conclusion: Small additives, big ones

Although polyurethane TPE anti-yellowing agent is just a small additive, the meaning it carries is extraordinary. It not only solves the long-lasting problem of TPE materials turning yellow, but also injects new vitality into the upgrading and replacement of agricultural equipment. As a poem says: “The true chapters are seen in the subtleties, and miracles are hidden in the ordinary.” Let us look forward to the fact that in this era full of opportunities, polyurethane TPE anti-yellowing agent can continue its wonderful chapters!
