Polyurethane gel amine catalyst 33LV: a new era catalyst to accelerate the process of polyurethane reaction
Introduction
Polyurethane (PU) is a polymer material widely used in the fields of construction, automobile, furniture, shoe materials, packaging, etc. Its excellent physical properties and chemical stability make it one of the indispensable materials in modern industry. However, in the production process of polyurethane, the selection of catalysts has a crucial impact on the reaction rate, product quality and production cost. In recent years, with the advancement of science and technology, new catalysts have emerged continuously. Among them, the polyurethane gel amine catalyst 33LV (hereinafter referred to as 33LV) has become a new era catalyst to accelerate the process of polyurethane reaction with its excellent performance.
This article will introduce the characteristics, application areas, product parameters and their advantages in polyurethane production in detail, helping readers to fully understand this new catalyst.
1. Basic principles of polyurethane reaction
1.1 Chemical reaction of polyurethane
The synthesis of polyurethane mainly involves two reactions: the addition reaction of isocyanate and polyol (i.e. polyurethaneization reaction) and the reaction of isocyanate and water (i.e. foaming reaction). Both reactions require catalysts to speed up the reaction process.
- Polyurethaneization reaction: Isocyanate (R-NCO) reacts with polyol (R’-OH) to form polyurethane (R-NH-CO-O-R’).
- Foaming Reaction: Isocyanate reacts with water to form carbon dioxide (CO?), and CO? acts as a foaming agent to expand the polyurethane material.
1.2 Function of catalyst
Catalytics play a crucial role in the polyurethane reaction. They can not only accelerate the reaction rate, but also regulate the equilibrium of the reaction, affecting the physical properties and chemical structure of the product. Traditional polyurethane catalysts mainly include organotin compounds, amine compounds, etc. However, these catalysts have certain limitations in terms of environmental protection and reaction control.
