Product Details

Specifications

Use HCFC-141B blowing agent for spray insulation

DQT-501B is high density spray blend polyols, it reacts with isocyanate to produce foam which has excellent performances, as follows,

 

1.fine and uniformity cells

2.low thermal conductivity

3.perfect fire resistance

4.excellent low temperature dimentional stability

 

It applies to all kinds of thermal insulation engineering which use the spray, such as storage warehouse, large pots, large-scale pipelines and construction roof and all types of abnormal thermal insulation projects. 

 

Our customer use our product for spray insulation.
