Amine Catalyst A33 33%TEDA DPG/DEG For PU Foam

Product overview:

Chinese name: polyurethane catalyst 33

alias: catalyst a33, polyurethane catalyst a33, catalyst a33, foaming catalyst a33, cas 280-57-9, dabco 33-lv, niax a-33, teda l33, foaming catalyst, polyurethane foaming catalyst, catalyst a-33, polyurethane catalyst a-33, liquid catalyst, liquid complex amine catalys, polyurethane catalyst a33 is a gel catalyst mainly used as polyurethane foam.

Content 33% triethylene diamine solution

Form solid

application flexible, semi-rigid, rigid urethane foam

Chemical composition:

33% solution of triethylenediamine.

triethylenediamine is solid at room temperature and is not convenient for use as a polyurethane catalyst. in industrial applications, it is often melted in small molecule diols and configured to be used as an alcohol solution with a mass fraction of 33% (or other concentrations).

commonly used diols are dipropylene glycol monoacetate, propylene glycol, diethylene glycol monoacetate (diethylene glycol), ethylene glycol and so on.
