Product Description

Rigid Polyurethane HFC-245fa blown spray System Formulated Blend Polyol for cold insulation 

DFR6224H is spray blend polyols, blowing agent is HCF245fa 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 industy etc.
