Those who have studied chemistry know the chemical term catalyst. Catalyst is a chemical substance often used in chemical experiments.

Polyurethane catalyst can shorten reaction time, improve production efficiency, selectively promote positive reaction and inhibit side reaction.

The catalysts commonly used in the synthesis of polyurethane and its raw materials mainly include amine catalysts and organometallic compounds. There are many kinds of amines an...

In fact, polyurethane catalysts are polymers formed from various types of isocyanates and compounds containing active hydrogen. Therefore, during the preparation and curing of p...

Vapor flame retardancy mechanism. That is to inhibit the freedom of chain growth in the combustion reaction, and play the role of flame retardant. Condensed phase mechanism of ...

Fiber flame retardant includes clothing, public facilities and transportation decorative cloth and fabric, and more and more need to consider the flame retardant problem, foreig...

Flame retardants are functional additives that give inflammable polymers flame retardancy. They are mainly designed for flame retardancy of polymer materials.

First, due to human factors, the flame retardant dose added to the extruded plate is very small, generally less than 10%, in order to make the flame retardant evenly distributed...

Flame retardants play their flame retarding role by several mechanisms, such as endothermic action, covering action, chain inhibition, asphyxiation of non-flammable gas, etc.

The varieties and consumption of flame retardants in China are still dominated by organic flame retardants, while the production and consumption of inorganic flame retardants ar...
