Donpanel 423PIR CP/IP base blend polyols for continuous PUR
INTRODUCTION
DonPanel 423/PIR is a kind of blend polyether polyol which adopts cyclopentane as foaming agent, takes polyol as the main raw material and is mixed with special auxiliary agent. It is suitable for thermal insulation of building boards, cold storage boards and other products.This material is specially developed for continuous line .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 dimensional stability and fire resistance
