Products Introduction
RIGID POLYURETHANE BLEND POLYOLS FOAM SYSTEM FOR PIPELINE INSULATION
DQT-502
This product is a type of blend polyols, which is specially researched for rigid PUF to produce thermal insulation pipes. It is widely used in steam pipes, 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)high temperature-resistance performance,long standing in 120°C
(3)excellent low temperature dimensional stability
