1. Introduction

Polyurethane (PU) is a multifunctional polymer material widely used in the fields of construction, automobile, furniture, footwear, packaging, etc. Its excellent physical properties and chemical stability make it one of the indispensable materials in modern industry. However, during the production process of polyurethane products, the selection and use of catalysts have a crucial impact on the quality and consistency of the product. This article will introduce Jeffcat TAP amine catalysts in detail and explore its role in improving the consistency of polyurethane products.

2. Basic concepts of polyurethane products

Polyurethane is a polymer compound produced by polymerization reaction of isocyanate and polyol. Its molecular structure contains carbamate groups (-NH-COO-), hence the name polyurethane. Polyurethane products have excellent elasticity, wear resistance, chemical resistance and heat insulation properties, and are widely used in foam plastics, elastomers, coatings, adhesives and other fields.

2.1 Classification of polyurethane

Polyurethane can be divided into the following categories according to its purpose and properties:

2.2 Production technology of polyurethane

The production process of polyurethane mainly includes the following steps:

1. Raw Material Preparation: Select suitable isocyanates and polyols, as well as necessary additives (such as catalysts, foaming agents, stabilizers, etc.).
2. Mixing reaction: Mix isocyanate and polyol in a certain proportion, add catalyst and other additives to carry out polymerization reaction.
3. Modeling: Inject the reaction mixture into the mold or spray it on the substrate for molding.
4. Post-treatment: After-treatment processes such as curing, cutting, and grinding of the molded products.

3. The role of catalysts in polyurethane production

Catalytics play a crucial role in polyurethane production. They not only accelerate the reaction rate of isocyanates and polyols, but also affect the selectivity of the reaction and the structure of the product. Choosing the right catalyst can significantly improve the quality and consistency of polyurethane products.

3.1 Classification of catalysts

Depending on chemical properties, catalysts in polyurethane production can be divided into the following categories:

3.2 Mechanism of action of catalyst

The catalyst accelerates the reaction rate of isocyanate and polyol by reducing the reaction activation energy. Specifically, the catalyst reduces the energy barrier of the reaction by forming an intermediate with the reactants, thereby increasing the reaction rate. In addition, the catalyst can also control the reaction through selective catalysisand the structure of the product.
