Description

Castor Oil, Polymd., Oxidized is a chemically modified derivative of castor oil, engineered through polymerization and oxidation processes to enhance its performance characteristics. This specialized product offers improved oxidative stability, viscosity, and film-forming properties compared to its base oil, making it a valuable functional additive and intermediate. It is essential for manufacturers in sectors such as coatings, lubricants, and polymer production, where tailored rheological behavior and enhanced durability are critical requirements.

Application

• As a viscosity modifier and tackifier in industrial lubricants and greases.
• Functioning as a plasticizer and stabilizer in PVC and other polymer formulations.
• Utilized as a key film-forming agent and binder in protective coatings, paints, and inks.
• Acting as a chemical intermediate for the synthesis of specialty surfactants and esters.
• Employed in the production of adhesives and sealants to improve flexibility and adhesion.
• Used in the formulation of cosmetic and personal care products as an emollient and texture enhancer.
• Serving as a release agent and mold lubricant in rubber and plastic processing.

Quality Control

Our Castor Oil, Polymd., Oxidized is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency in key parameters such as acid value, viscosity, color, and peroxide value. Certificates of Analysis (COA) documenting these specifications are provided and available upon request, supporting 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 (15-25°C/59-77°F). Due to its easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation to maintain product integrity. Keep away from strong oxidizing agents and heat sources.
