Rigid Polyurethane Blend polyols for Spray Insulation
Rigid Polyurethane Blend polyols  for Spray Insulation(DQT-501A)      
Product Introduction

DQT501A is spray blend polyols, 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.
