Specifications

Blend polyether polyols, HCFC-141B foaming agent, used for spray insulation

DQT-501A is spray blend polyether polyols, it reacts with isocyanate to produce foam has excellent performances, which are 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 projects use the spray, such as storage room, large pots, large-scale pipelines and construction our-wall or inner-wall etc. 

 

This is our second factory we use our own polyurethane.
