B
Product Introduction:
It is high density spray blend polyols, it reacts with 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 dimentional 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.
