BioPolyol TD

Bio Polyol TD 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 description - Polyol is synthesized from tall oil by amidation/esterification method with polyfunctional alkanolamine. It contains secondary amine and primary hydroxyl functional groups. Polyol is difunctional.
