BioPolyol RD

Bio Polyol RD is a bio based polyol, mainly for rigid PU foam production. For rigid foam production this polyol is used in mixture with cross-linking polyols whose functionality is at least five. Our suggested ratio between Bio Polyol TD and cross-linking polyol is approx. 80:20 by mass.

General descriptionPolyol is synthesized from rapeseed oil by transamidation/transesterification method with polyfunctional alkanolamine. It contains secondary amine and primary hydroxyl functional groups. Polyol is difunctional.
