Donfoam 822Pir HCFC, 141B Base Blend Pololols enim continua PIR Clausus spumam
Introductio
DonFoam 822/PIR is a kind of blend polyols with hcfc-141b 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:
I. Foam habet uniformis viribus et dimensional stabilitatem in omnibus directiones
II. Et spumam products potest interficiam in diversas figuras secundum ad opus est productum
III. Optimum scelerisque Nulla perficientur
