Specifications
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
