Donpanel 415 HFC-365mfc base blend polyols for PUR

INTRODUCTION DonPanel 415 is a kind of blend polyether polyols with HFC-245fa as foaming agent, taking polyol as the main raw material and mixed with special auxiliary agent. It is suitable for thermal insulation of building boards, cold storage boards and other products.The polyurethane product prepared by reacting it with isocyanate has the following advantages: -- No greenhouse effect and does not damage the ozone layer -  Good fluidity and uniform foam density -- Excellent insulation, dimensional stability and adhesion
