Professional China Low Hardness Polyurethane System - Donpipe 303 CP/IP base blend polyols for pipeline insulation – INOV

Donpipe 303 CP/IP base blend polyols for pipeline insulation

INTRODUCTION

Donpipe 303 is one type of blend polyols foam system for pipe insulation, with cyclopentane as foaming agent. 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
