Description

Castor Oil,Polymer With Adipic Acid,Diethylene Glycol,Fumaric Acid And Phthalic Anhydride CAS NO 68650-73-7 is a specialized polyester polyol derived from castor oil, a renewable resource. This polymer is valued for its unique combination of flexibility, hydrolytic stability, and adhesion properties imparted by its complex chemical structure. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries for formulating high-performance, sustainable products.

Application

• Polyurethane Coatings & Inks: Acts as a key polyol component in the synthesis of flexible, durable, and chemical-resistant polyurethane coatings for industrial, automotive, and wood-finishing applications.
• Adhesives & Sealants: Used to formulate high-performance polyurethane adhesives and sealants with excellent bonding strength, flexibility, and moisture resistance.
• Elastomers: Serves as a building block for castable and thermoplastic polyurethane elastomers, providing resilience and toughness in molded parts, rollers, and gaskets.
• Resin Modification: Employed as a modifier for alkyd and other polyester resins to enhance flexibility, adhesion, and impact resistance in final formulations.
• Sustainable Material Production: As a bio-based polyol, it is integral to developing "green" polyurethane systems with a reduced carbon footprint for environmentally conscious markets.
