Description

Tridecyltrimellitate is a high-performance, synthetic ester plasticizer derived from trimellitic anhydride and tridecyl alcohol. This compound is valued for its exceptional permanence properties, including low volatility, excellent resistance to extraction, and superior thermal stability, making it a critical component in demanding polymer formulations. It is primarily sought by manufacturers in the plastics, wire and cable, and specialty polymer industries for applications requiring long-term durability and performance under harsh conditions.

Application

• Primary plasticizer for high-temperature PVC (polyvinyl chloride) wire and cable insulation and jacketing.
• Key component in the formulation of high-performance synthetic rubbers and elastomers requiring low migration.
• Used in the production of automotive interior parts, such as dashboards and upholstery, for enhanced heat and light aging resistance.
• Plasticizer for specialty adhesives, sealants, and caulks where low volatility and permanence are critical.
• Formulation additive for gaskets, hoses, and other industrial rubber goods exposed to elevated temperatures.
• Used in the manufacture of coated fabrics and tarpaulins to improve flexibility and durability.
• Plasticizer for plastisols in rotational molding and spread coating applications.

Quality Control

Our Tridecyltrimellitate is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is tested against rigorous internal specifications, which typically include assay, acid value, color, and specific gravity. A Certificate of Analysis (COA) detailing these results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to minimize moisture absorption.
