Product Description:

Rigid Polyurethane Blend Polyols forSpray Insulation  (DQT-501A )  
Product Introduction

DQT-501Ais spray blend polyols, it reacts with isocyanate to produce foam which hasexcellent performances, which are as follows,

 1) fine and uniformity cells

 2) low thermal conductivity

 3) perfect fire resistance

 4) excellent low temperature dimentionalstability.

Itapplies to all kinds of thermal insulation projects which use the spray, suchas cold rooms,large pots, large-scale pipelines and construction out-wall orinner-wall etc.
