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…
