Ürün Açıklaması

Polyurethane Spray Foam PU Chemicals Two Component Closed Cell Spray Foam Insulation

DQT-501C is spray blend polyols, blowing agent is 365mfc/245fa instead of HCFC-141B, it reacts with isocyanate to produce foam which has excellent performances, which are as follows,

  1) fine and uniformity cells

  2) low thermal conductivity

  3) perfect flame 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.
