Polyurethane Foam for constrution insulation

 

 

 

1. Introduction

 

Part A is high density spray blend polyols, it reacts with Part B--isocyanate to produce foam which has excellent performances, which are as follows.

 

l        Fine and uniformity cells.

 

l        Low thermal conductivity.

 

l        Perfect flame resistance

 

l        Good low temperature dimensional stability.

 

It applies to all kinds of thermal insulation engineering which use the spray technology, such as cold storages, pot, large-scale pipelines, construction roofs and all types of abnormity thermal insulation projects.
