fine and uniformity cells

 

Product Introduction

 Rigid Polyurethane Blend Polyols Foam  System for Spray 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 dimentional 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.
