Donpipe 322 HCFC-141b base blend polyols for pipeline shell

INTRODUCTION

DonPipe 322 is a kind of blend polyols with hcfc-141b as foaming agent, taking polyol as the main raw material, mixing with a special auxiliary. This material suitable for outer thermal insulation shells which are used for water, oil and gas pipelines .The polyurethane product prepared by reacting it with isocyanate has the following advantages:

– good compressive strength and dimensional stability

– high close-cell rate and good waterproof performance

– good insulation performance
