Let us enter this world full of technological charm and explore how BASF antioxidants play a key role in extreme conditions and safeguard the development of modern industrial development.
Overview of BASF antioxidants
BASF antioxidants are a series of chemicals specially designed to prevent or delay the oxidative degradation of materials. They are the “secret of longevity” in the material industry. These products are mainly divided into two categories: primary antioxidants and auxiliary antioxidants. Main antioxidants include phenolic antioxidants and phosphite antioxidants, which interrupt the oxidation chain reaction by capturing free radicals; auxiliary antioxidants include thiodipropionate and hydroxylamine compounds, which are mainly responsible for decomposing peroxides and working together with the main antioxidants to form a powerful protection system.
Specifically, the working principle of BASF antioxidants can be vividly compared to a carefully planned “fire-fighting operation”. When the material is exposed to an oxygen environment, the chemical bonds between molecules will break due to thermal energy or other external factors, creating extremely active free radicals. These free radicals are like flames spreading everywhere. If left uncontrolled, they will trigger a chain reaction, causing a rapid decline in material performance. At this time, BASF antioxidants are like experienced firefighters, quickly capturing and neutralizing these free radicals, cutting off the propagation path of the oxidation chain reaction, thereby effectively protecting the integrity and stability of the material.
In order to more intuitively understand the types and characteristics of BASF antioxidants, the following table summarizes the main product categories and characteristics:
| Antioxidant Category | Represents Product | Main Functions | Application Fields |
|---|---|---|---|
| Phenol antioxidants | Irganox 1076 | Catch free radicals | Polyolefins, engineering plastics |
| Phosophites | Irgafos 168 | Decomposition of hydroperoxide | Polyolefins, polyesters |
| Thiodipropionate | Ultranox 626 | Assisted antioxidant | ABS, PC/ABS alloy |
| Trumped amines | Chimassorb 944 | Light stabilization | Plastic film, fiber |
From the table above, different types of BASF antioxidants have their own expertise and can provide excellent protection solutions for specific materials and application environments. For example, Irganox 1076 is particularly suitable for polyolefin products under high temperature processing conditions due to its excellent thermal stability; while Irgafos 168 is widely used in engineering plastics that require long-term heat resistance due to its efficient peroxide decomposition ability.
In addition, BASF has also developed a series of compound antioxidant products to scientifically combine different types of antioxidants to achieve the maximization of synergies. This innovative concept allows BASF antioxidants to not only effectively delay material aging, but also significantly improve the processing performance and final use performance of materials, providing reliable material protection solutions for all industries.

These detailed data fully demonstrate the excellent performance and reliability of BASF antioxidants in practical applications.
Performance and advantages of BASF antioxidants in high temperature environments
In extreme high temperature environments, BASF antioxidants show amazing stability and protective performance, which can be called the “steel shield” of the material industry. Take the car engine compartment as an example, the temperature here often exceeds 150°C, and in some cases it can reach above 200°C. Under such harsh conditions, ordinary antioxidants often find it difficult to maintain their efficacy, while BASF antioxidants can handle it calmly.
Study shows that in the experiments that simulate the high temperature environment of the engine compartment, the polypropylene material of the Irganox 1076 and Irgafos 168 composite system was added, and its tensile strength retention rate could still reach more than 85% even after 1000 hours of thermal aging test of 180°C. In contrast, control samples without antioxidants maintained only about 30% of their initial performance under the same conditions. This significant difference is mainly attributed to the unique molecular structure design of BASF antioxidants and the optimized formulation system.
Specifically, the outstanding performance of BASF antioxidants in high temperature environments is reflected in the following aspects:
First of all, they have excellent thermal stability. Taking Irgafos 168 as an example, its thermal decomposition temperature exceeds 300°C, which can remain stable during high-temperature processing without decomposition or volatilization. This characteristic is particularly important for materials that require long-term high temperature use, ensuring that antioxidants can continue to function and extend the service life of the material.
Secondly, BASF antioxidants exhibit excellent synergies. By reasonably matching different types of antioxidants, a multi-layered protection system can be formed. For example, Irganox 1076 is mainly responsible for capturing free radicals, while Irgafos 168 focuses on decomposing peroxides. The two work together to build a strong antioxidant barrier. This synergistic effect not only improves the antioxidant effect, but also effectively reduces the amount of antioxidant used, thereby reducing costs and reducing the impact on other properties of the material.
Thirdly, these antioxidants have good mobility and durability. Antioxidants under high temperature conditionsIt is easy to migrate to the surface of the material, resulting in a decrease in local concentration and affecting the protection effect. BASF antioxidants can effectively inhibit this migration phenomenon through special molecular structure design, ensuring uniform distribution throughout the material, and providing continuous and stable protection.
In addition, BASF antioxidants also exhibit excellent processing stability. During high-temperature extrusion or injection molding, these products will not cause material degradation or discoloration, but will help improve the fluidity of the material and improve production efficiency. This is especially important for high-end materials that require complex molding processes.
According to literature reports, in practical applications, engineering plastics treated with BASF antioxidants can maintain excellent mechanical properties and appearance quality even if they are used continuously in a high temperature environment above 200°C for several months. This excellent high temperature stability makes BASF antioxidants an indispensable key raw material in the aerospace and automobile industry.
Examples of application of BASF antioxidants in various industries
BASF antioxidants have been widely used in multiple industries with their excellent performance, providing reliable solutions for material protection in different fields. The following are several typical application examples:
Automotive Industry
In the automotive industry, BASF antioxidants are widely used in the manufacturing of engine peripheral components. For example, in the production of turbocharger housings, high-temperature engineering plastics such as PPS (polyphenylene sulfide) or PEEK (polyether ether ketone) are usually used. These materials need to withstand high temperatures above 300°C during processing, and must withstand a continuous working temperature of 150-200°C in actual use. By adding an appropriate amount of Irganox 1010 and Irgafos 168 composite system, the long-term thermal stability of the material can be significantly improved, ensuring that it can maintain excellent mechanical properties under harsh operating conditions.
Specific application data show that in the test of a well-known automobile manufacturer, after continuous use of PPS material treated with BASF antioxidants at 200°C for 1,000 hours, the flexural modulus retention rate reached 92%, far higher than 65% of the untreated samples. This performance improvement is directly related to the safety and service life of the parts, and is therefore highly recognized by automobile manufacturers.
Electronics
In the field of electronic and electrical appliances, BASF antioxidants are mainly used to protect high-performance engineering plastics used in precision components such as connectors and sockets. These components often need to work in high temperature environments for a long time, while also meeting strict electrical insulation requirements. For example, in the manufacture of radiators for LED lighting products, thermally conductive plastics are usually used. This material needs to withstand high temperatures above 260? during processing, and the temperature during operation may also reach above 120?.
Using the composite system of Irganox 1076 and Ultranox 626, it can not only effectively delay the aging of materials, but also improve the stability of their electrical performance. The experimental results show that after continuous heating at 150°C for 100 hours, the volume resistivity change is less than 5%, which is significantly better than the 20% change range of untreated samples.
Medical Devices
In the field of medical devices, BASF antioxidants also play an important role. Especially in the production of disposable medical consumables, such as syringes, infusion tubes, etc., the PP (polypropylene) or PE (polyethylene) materials used need to undergo strict sterilization and usually adopt steam sterilization or radiation sterilization. These sterilization processes will cause a certain degree of oxidation and degradation of the material, affecting its physical properties and biocompatibility.
This problem can be effectively alleviated by adding a composite system of Irganox 1076 and Irgafos 168. Experimental data show that after 25kGy radiation sterilization, the elongation retention rate of PP materials treated with BASF antioxidants reached 85%, while the untreated samples were only 50%. This performance improvement is critical to ensuring the safety and reliability of medical devices.
Building Materials
In the field of building materials, BASF antioxidants are widely used in the production of PP-R pipes, PVC flooring and other products. In particular, PP-R pipelines, as an important hot water transport material, need to be used for a long time at a temperature of 70-95°C. To ensure long-term heat pressure resistance, Irganox 1076 and Irgafos 168 composite systems are usually added to the formula.
Experimental studies show that the life of PP-R materials treated with BASF antioxidants can be extended to more than 50 years in long-term hydrostatic tests under 80°C and 1.0 MPa, far exceeding the 25 years required by the industry standard. This performance improvement not only improves the market competitiveness of the product, but also brings higher security guarantees to users.
Comparative analysis of BASF antioxidants and other brands of antioxidants
In the antioxidant market, although there are a variety of brands and product choices, BASF antioxidants stand out with their unique advantages and become the first choice for many companies. The following compares and analyzes BASF antioxidants with other well-known brands from several key dimensions:
Performance comparison
| Compare items | BASF Antioxidants | Other well-known brands | Advantage Analysis |
|---|---|---|---|

| Processing performance | Improving liquidity | Neutral Effect | Improve production efficiency and reduce energy consumption |
| Synergy Effect | Significant | Winner | Complex system has better effect and lower cost |
| Migration | Low | High | The long-term use effect is more stable |
From the perspective of thermal stability, BASF antioxidants show obvious advantages. For example, the thermal decomposition temperature of Irgafos 168 exceeds 300°C, while similar products usually only reach 280-300°C. This gap is particularly important in high-temperature processing and use environments, ensuring the long-lasting and stable material properties.
In terms of processing performance, BASF antioxidants can not only effectively delay material aging, but also improve material flow and improve production efficiency. According to actual application data, during the PP injection molding process, the flow length of the material added with BASF antioxidants can be increased by more than 15%, which is significantly better than similar products of other brands.
Regarding synergistic effects, the BASF antioxidant complex system performed well. Through reasonable formula design, the effect of 1+1>2 can be achieved, which not only improves the overall antioxidant performance, but also effectively reduces the amount of individual antioxidant, thereby reducing costs. In contrast, other brands of products often find it difficult to achieve the same synergistic effect when combined.
As for mobility, BASF antioxidants adopt special molecular structure design, which can effectively inhibit migration to the surface of the material. This is especially important in long-term use, as migration will lead to a decrease in local antioxidant concentrations, affecting the protection effect. Experimental data show that after continuous heating at 180°C for 100 hours, the mobility of BASF antioxidants is less than 0.5%, while other brand products are usually between 1-2%.
Cost-benefit analysis
Although BASF antioxidants are slightly higher than some competitors, their advantages are more obvious from the perspective of comprehensive cost. Due to higher efficiency and better synergistic effects, the total amount of antioxidants can often be reduced in actual use. For example, in PP-R pipe materials, the amount of BASF antioxidants added is usually about half that of other brands, but it can still achieve better performance.
In addition, the improvement in processing performance brought by BASF antioxidants can also bring significant cost savings. Taking PP injection molding as an example, materials treated with BASF antioxidants can improve production efficiency by 10-15% and reduce energy consumption by 5-8%. These indirect cost savings can often offset the price difference.
User feedback and evaluation
Based on the use of multiple companiesFeedback, BASF antioxidants show high reliability in practical applications. A well-known automaker said: “We have used BASF antioxidants for many years. The products performed well in high temperature environments, significantly extending the service life of parts.
