High Density Polyurethane Blend Polyols for Pipe Shells 

 

High Density Polyurethane Blend Polyols for Pipe Shells

           DQT-502SW

 

Products Introduction

This product is a type of blend polyols with 100% water as blowing agent, which is specially researched for rigid PUF to produce thermal insulation pipe shells. It is mainly used in liquefied nature gas running pipes, oil pipes and other fields. The characteristics are as follows:

(1)good flowability, by regulating formula to suit different pipe diameters.

(2)excellent foam mechanical properties  

(3)excellent high/low temperature dimensional stability
