Product Description
Double-component Rigid Polyurethane Spray Foam Insulation
Isocyanate (MDI) and Blended Polyol
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.
- 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 storages, pot, large-scale pipelines, construction roofs and all types of abnormity thermal insulation projects.
