Description

Castor Oil, Polymer With Adipic Acid, Diethylene Glycol And Phthalic Anhydride is a high-performance, modified polyester resin derived from renewable castor oil. This specialized polymer offers a unique combination of flexibility, adhesion, and chemical resistance, making it a valuable intermediate for demanding industrial formulations. It is primarily sought after by manufacturers in the coatings, adhesives, and specialty plastics industries seeking to enhance product durability and performance.

Application

• Flexible Coatings and Inks: As a key resin component for producing high-flexibility, impact-resistant surface coatings and printing inks.
• Adhesives and Sealants: Used to formulate polyurethane-based adhesives and sealants with excellent bonding strength and elasticity.
• Plasticizer and Modifier: Acts as a polymeric plasticizer and modifier for PVC and other polymers to improve low-temperature flexibility and reduce migration.
• Elastomer Production: Serves as a polyol component in the synthesis of polyurethane elastomers for wheels, rollers, and gaskets.
• Wire and Cable Insulation: Imparts flexibility and flame retardancy to insulation and jacketing compounds for electrical cables.
• Industrial Fabric Coatings: Used in coatings for tarpaulins, conveyor belts, and other technical textiles to provide waterproofing and durability.

Quality Control

Our Castor Oil, Polymer With Adipic Acid, Diethylene Glycol And Phthalic Anhydride is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent properties such as hydroxyl value, acid value, and viscosity. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong acids and organic solvents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent moisture absorption and contamination.
