It is a kind of soft foam with excellent performance due to its high forming resilience. It has the characteristics of light weight, softness, high resilience and high hand comfort, and is also widely
The amount of foam stabilizer determines the cell size of foam product structure. The larger the cell, the thinner it will be. If too much battery is used, it will shrink. To find this, too few cells
After all, polyurethane is also a chemical industry, and these problems actually involve every raw material. Every raw material involved in the chemical reaction is very important. Both main materials
For a long time, automobile manufacturers have put the improvement of interior comfort in a very important position.Now, the environment inside the car body, especially the smell and smoke inside the
Downstream polyurethane materials are mostly used in the form of sponge. Amines are often selected as catalysts for these materials. We will briefly introduce several.First, triethylenediamine (TEDA),
Polyether amine (PEA): It is a polymer with polyether structure as the main chain and amine as the terminal active functional group. Polyether amine is made of polyethylene glycol, polypropylene glyco
What is tertiary amine catalystFor the preparation of polyurethane foam, there are generally three reactions: isocyanate hydroxyl reaction, isocyanate water reaction, isocyanate isocyanate reaction. T
During the preparation of polyurethane foam, the role of catalyst is mainly to adjust the speed of foaming reaction and gel reaction, so as to keep a good balance between them.1. Amine catalystTriethy
Polyurethane polymer materials have the advantages of wear resistance, high temperature resistance, good adhesion, convenient construction, etc., but some polyurethane materials have poor waterproof a
