Product Introduction

RIGID POLYURETHANE BLEND POLYOLS FOAM SYSTEM FOR SPRAY INSULATION

DQT-501B is high density spray blend polyols, it reacts with isocyanate to produce foam which has excellent performances as below,

    1) fine and uniformity cells

    2) low thermal conductivity

    3) perfect fire resistance

    4)excellent low temperature dimentional stability .

 

It applies to all kinds of thermal insulation engineering which use the spray, such as cold warehouses, pots, large-scale pipelines, construction roofs and all types oabnormal thermal insulation projects.
