1. Introduction

Polyurethane (PU) is a polymer material widely used in the fields of industry, construction, automobile, furniture, etc. Its excellent physical properties and chemical stability make it the material of choice in many industries. However, the choice of catalyst is crucial in the production process of polyurethane. The catalyst not only affects the reaction rate, but also directly affects the performance of the final product. This article will introduce a new type of delayed amine catalyst C225 in detail, discussing its characteristics, application areas, product parameters and usage methods, so as to help readers better understand and use this efficient catalyst.

2. What is delayed amine catalyst C225?

The delayed amine catalyst C225 is a highly efficient catalyst specially designed for polyurethane formulations. It belongs to an amine catalyst, has the characteristics of delayed reaction, can provide longer operating time during the polyurethane reaction process, while ensuring excellent physical properties of the final product. C225 catalyst is widely used in a variety of polyurethane products such as soft foam, rigid foam, coatings, adhesives, etc.

3. Characteristics of Retarded amine Catalyst C225

3.1 Delay reaction characteristics

The major feature of the delayed amine catalyst C225 is its delayed reaction characteristics. This means that in the early stages of the polyurethane reaction, C225 can effectively extend the reaction time, allowing the operator to have enough time for mixing, casting and forming. This characteristic is particularly suitable for polyurethane products requiring complex molding processes.

3.2 High-efficiency catalytic performance

Although C225 has delayed reaction characteristics, its catalytic efficiency is very high. Once the reaction begins, C225 can quickly accelerate the reaction process, ensuring that the polyurethane material reaches the ideal curing state in a short time.

3.3 Excellent physical properties

Polyurethane products using C225 catalysts generally have excellent physical properties, including high elasticity, good wear resistance, excellent chemical resistance and weather resistance. These characteristics have enabled the C225 catalyst to be widely used in many industries.

3.4 Environmentally friendly

C225 catalyst inThe impact on the environment during production and use is relatively small, and it meets the requirements of modern industry for environmental protection. Its low volatility and low toxicity make it less effective on the health of the operator during the production process.

4. Application fields of delayed amine catalyst C225

4.1 Soft foam

Soft foam is one of the common applications in polyurethane materials and is widely used in furniture, mattresses, car seats and other fields. The application of C225 catalyst in soft foam production can provide longer operating time while ensuring good elasticity and comfort of the foam.

4.2 Hard foam

Rough foam is mainly used in building insulation, cold chain transportation and other fields. The application of C225 catalyst in the production of rigid foam can effectively extend the reaction time, making it easier to form foam materials in complex molds, while ensuring that the foam has excellent thermal insulation properties and mechanical strength.
