Let you know polyurethane catalyst in one minute
Introduction to polyurethane catalyst
According to the definition of the International Union of Pure and Applied Chemistry (IUPAC) in 1981, a catalyst is a substance that changes the reaction rate but does not change the total standard Gibbs free energy of the reaction. It can shorten reaction time, improve production efficiency, selectively promote positive reaction and inhibit side reaction.
In the production process of polyurethane products, the main functions of the catalyst are:
• Promote chain growth response
• Promote the reaction rate of some chemical reactions in the reaction system
• Regulate the competitive reaction, promote the main reaction, slow down or inhibit the side reaction
