Chinese Professional Pu System For Pipeline Insulation - Donfoam 824PIR HFC-245fa base blend polyols for continuous PIR block foam – INOV Detail:
Donfoam 824PIR HFC-245fa base blend polyols for continuous PIR block foam
INTRODUCTION
DonFoam 824/PIR is a kind of blend polyols using hfc-245fa foaming agent, with polyol as the main raw material, mixed with special auxiliary agent, suitable for the insulation of construction, transportation, shell and other products. This material is specially developed for continuous line .The polyurethane product prepared by reacting it with isocyanate has the following advantages:
– Eco-friendly, without destroying the ozone layer
– High compressive strength and good homogeneity of isotropic strength
– Excellent thermal insulation performance and dimensional stability
