Detailed Product Description

 

High-quality Rigid Spray Polyurethane Foam Systems for Roof

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.
