Product Description
About polyol and isocyanate
It is spray-applied, closed-cell polyurethane foam system with high fire resistance properties. It applies to all kinds of spray-applied thermal insulation engineering, such as building exterior and interior, cold rooms, large-scale pipeline, etc.
Raw Material for Rigid Foam Polyurethane Polyether Polyol & Iso
DQT-501C is spray blend polyols, blowing agent is 365mfc/245fa instead of HCFC-141B, it reacts with iso to produce foam which has excellent performances, which are as follows:
1) fine and uniformity cells
2) low thermal conductivity
3) perfect fla-me resistance
4) good low temperature dimensional stability.
It applies to all kinds of thermal insulation engineering which uses the spray technology, such as cold rooms, pots, large-scale pipelines and construction metope etc.
