The polyester polyols with molecular weight of 500-4000G/Mol have the advantages of low chromaticity and stable activity. The TPU made from polyester polyols has the advantages of stable viscosity, easy cutting, excellent mechanical strength, high wear resistance, tear resistance and fast molding, and can adjust molecular weight according to customer requirements.
This series of polyester polyols can be widely used in TPU elastomer hot melt adhesive, shoe material, pipe, film, cable sheath, conveyor belt and other polyurethane products.|
