Specifications

Polyurethane Foam Blend Polyols for continuous Boards

DBC-402A

Product Introduction

It uses special polyether polyols as the main raw materials, with special additives to constitute blend polyols, the characteristics are as follows,

1,good flowability in the reactivity process, the foam density distributes uniformity, with excellent dimensional stability and cohesiveness.

2,it can meet different requirements of continuous sandwich board product lines
