1. Introduction

Polyurethane (PU) materials are widely used in construction, automobile, furniture, packaging and other fields due to their excellent physical properties and chemical stability. Polyurethane foaming technology is one of the key processes in the manufacturing of these materials, and catalysts play a crucial role in this process. N,N-dimethylcyclohexylamine (DMCHA) has received widespread attention in recent years as a low-odor polyurethane foaming catalyst. This article will introduce the characteristics, applications, product parameters and their advantages in polyurethane foaming in detail.

2. Overview of polyurethane foaming technology

Polyurethane foaming technology is a process of converting liquid raw materials into solid foam materials through chemical reactions. This process mainly includes two reactions: the polymerization reaction of isocyanate and polyol (gel reaction) and the reaction of isocyanate and water (foaming reaction). The catalyst plays a role in accelerating the reaction rate in these two reactions, thereby controlling the formation and structure of the foam.

2.1 Gel reaction

Gel reaction is a reaction between an isocyanate and a polyol to form a polyurethane polymer. This reaction determines the strength and elasticity of the foam.

2.2 Foaming reaction

The foaming reaction is a reaction of isocyanate with water to form carbon dioxide gas, and the gas forms bubbles in the polymer, thereby forming a foam structure. This reaction determines the density and porosity of the foam.
