Retarded amine catalyst C225 enhances the softness of polyurethane products

3月 11th, 2025 News

Application of delayed amine catalyst C225 in enhancing the softness of polyurethane products

Introduction

Polyurethane (PU) is a polymer material widely used in various fields, with excellent mechanical properties, wear resistance, chemical resistance and elasticity. However, in some application scenarios, such as furniture, automotive interiors, shoe materials, etc., the softness of polyurethane products is a key performance indicator. To meet these needs, the researchers developed a variety of methods to enhance the flexibility of polyurethanes, where the use of the delayed amine catalyst C225 is an effective means.

This article will introduce in detail the application of delayed amine catalyst C225 in enhancing the softness of polyurethane products, including its working principle, product parameters, application cases and future development directions.

1. Working principle of delayed amine catalyst C225

1.1 Basic concepts of delayed amine catalysts

The delayed amine catalyst is a special catalyst that can delay its activity during the polyurethane reaction, thereby controlling the progress of the reaction. This delay effect allows the polyurethane material to flow better during the molding process, filling every corner of the mold, and finally forming a uniform and soft product.

1.2 Chemical structure of C225

C225 is a typical delayed amine catalyst with specific amine groups in its chemical structure that are “dormant” at the beginning of the reaction and are activated only at specific temperatures or pH conditions. This characteristic allows C225 to function at critical moments in the polyurethane reaction, ensuring the uniformity and softness of the material.

1.3 Mechanism of delay effect

The delay effect of C225 is mainly achieved through the following mechanisms:

  1. Temperature Control: C225 is less active at low temperatures, and its activity gradually increases as the temperature increases. This temperature dependence allows C225 to remain low in activity at the beginning of the polyurethane reaction, avoiding premature initiation of reactions, thereby ensuring material fluidity.

  2. pH control: The activity of C225 is also affected by pH. Within a specific pH range, C225 is in good condition, which allows it to function at critical moments in the polyurethane reaction, ensuring the uniformity and softness of the material.
