Product Description

Rigid PU HFC-245fa based spray Formulated System Blend Polyether Polyol for cold storage

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.
