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.
