Product Description

Introduction:
This series of polyols are mainly aromatic polyester polyols prepared by polycondensation or modification of phthalic anhydride, diethylene glycol and other raw materials. They are mainly used in the field of hard foam and adhesives. They have the advantages of low odor, low color, high reaction activity, excellent hydrolysis stability, high aromatic content, good stability and fluidity of composite materials, And the product structure can be adjusted according to customer requirements.
Product use:
This series of polyester polyols can be widely used in refrigerator, cold storage, spraying, solar energy, thermal pipelines, building insulation and other areas of hard foam composition, some of the adhesive products.
