A brief discussion on polyurethane catalysts

A-1 is a solution composed of 70% bis(dimethylaminoethyl) ether and 30% dipropylene glycol , mainly used for soft polyether polyurethaneFoam plasticProduction of foaming tertiary amine Catalyst, also known as front-stage catalyst. A-1 has a particularly strong catalytic effect on water, so it can reduce the foam density. It has catalytic activity for both polyurethane foaming…
