Product Introduction
DQT-501B is an high density spray blend polyols,the foam produced by reacting wih isocyanate has excellent performances, which are as follows,
1) fine and uniformity cells
2) low thermal conductivity
3) perfect flame redartant
4)good low temperature dimentional stability .
It applies to all kinds of thermal insulation engineering which use the spray technology,such as cold storage,pot,large-scale pipeline, construction top floor and all types of abnormity thermal insulation engineering.
