BioPolyol TT

Bio Polyol TT is a bio based polyol mainly for rigid polyurethane 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 TT and cross-linking polyol is approx. 80:20 by mass.

General description -Polyol is synthesized from tall oil by esterification method with polyfunctional alkanolamine. It contains primary hydroxyl functional groups and tertiary amine groups. This polyol is catalytically more active and can be used for spraying PUR formulations.  Polyol is difunctional.
