Detailed Product Description

 

Rigid Spray Polyurethane Foam Systems for Wall

1. Introduction

This is spray blend polyols. It reacts with isocyanate to produce foam which has excellent performances, which are as follows.

●       Fine and uniformity cells.

●       Low thermal conductivity.

●       Perfect flame resistance

●       Good low temperature dimensional stability.

It applies to all kinds of thermal insulation engineering which use the spray technology, such as cold rooms, pots, large-scale pipelines and construction metope etc.
