Description

Castor Oil, Polymer With 1,4-Cyclohexanedimethanol, Hydroxybutanedioic Acid, Maleic Anhydride And Trimellitic Anhydride is a high-performance, synthetic polyester polyol derived from renewable castor oil. This specialized polymer is engineered to provide enhanced thermal stability, chemical resistance, and mechanical properties compared to standard polyols. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking sustainable and high-performance polymer solutions.

Application

• High-Performance Polyurethane Coatings: Used as a polyol component in formulations for industrial, automotive, and protective coatings requiring excellent weatherability, adhesion, and chemical resistance.
• Specialty Adhesives and Sealants: Serves as a key ingredient in structural adhesives, potting compounds, and flexible sealants where toughness and durability are paramount.
• Elastomers and Thermoplastic Polyurethanes (TPU): Imparts flexibility, hydrolytic stability, and low-temperature performance to cast elastomers, fibers, and TPU sheets.
• Composite Materials: Acts as a reactive modifier or crosslinker in resin systems for composites, enhancing impact resistance and interfacial bonding.
• Industrial Resins: Utilized in the synthesis of alkyd and polyester resins for applications demanding high gloss and hardness.
• Sustainable Polymer Formulations: Provides a bio-based component for companies aiming to improve the environmental profile of their polymer products without sacrificing performance.

Quality Control

Our production of Castor Oil, Polymer With 1,4-Cyclohexanedimethanol, Hydroxybutanedioic Acid, Maleic Anhydride And Trimellitic Anhydride adheres to strict quality management protocols. Each batch is characterized for critical parameters including hydroxyl value, acid value, viscosity, and color to ensure consistency and performance. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (typically 15-25°C). Keep away from heat sources and open flame. Under these conditions, the product is stable for extended periods. Ensure containers are kept tightly sealed when not in use to prevent moisture absorption.
