Donpipe 301 water base blend polyols for pipeline insulation

INTRODUCTION

This product is a type of blend polyols with water as foaming agent, 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 150℃

(3) excellent low temperature dimensional stability
