Inov Polyurethane Phthalic Anhydride Polyester Polyol Used in Rigid Foam Composites

Rigid Foam Series

INTRODUCTION The series of polyols are mainly based on raw materials such as phthalic anhydride and diethylene glycol. It is mainly used in the field of rigid foam and can also be applied in the field of adhesives. It has the advantages of low odor, low chroma, high reactivity, excellent hydrolysis resistance, high aromatic content, stability of composition and good fluidity. The product structure can be adjusted according to customer requirements. APPLICATION This series of polyester polyols can be widely used in rigid foam system such like refrigerators, cold storage, spraying, solar energy, thermal pipelines, building insulation, etc., and some are suitable for adhesive products.
