New Products From This Supplier
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.
1. Fine and uniformity cells.
2. Low thermal conductivity.
3. Perfect flame resistance
4. 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.
