Donpipe 311 water base blend polyols for pipeline holder

Donpipe 311 water base blend polyols for pipeline holder

INTRODUCTION DonPipe 311 is a kind of blend polyether polyol with water as foaming agent, polyol as the main raw material, mixed with special auxiliary agent. It is developed for propping of water, oil or gas pipelines, furniture and other products，also with moisture proof and heat preservation functions . The polyurethane product prepared by reacting it with isocyanate has the following advantages: -- Environment friendly, without destroying the ozone layer -- High compressive strength of foam -- Fine and smooth Foam cell , with good waterproof and moisture-proof performance
