Specifications

HFC-365mfc/HFC-245fa blowing agent, used for spray insulation

DQT-501C is spray blend polyols, foaming agent is HFC-365mfc/HFC-245fa instead of HCFC-141B, 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. 

 

This is our second factory we use our own polyurethane to built it.
