Description

Decyl Octyl Hydrogen Benzene-1,2,4-Tricarboxylate is a specialized diester plasticizer derived from trimellitic acid, offering a unique balance of performance characteristics for demanding polymer formulations. Its primary value lies in providing excellent permanence properties, including low volatility and resistance to extraction, which are critical for long-term product durability. This compound is essential for manufacturers in the plastics, coatings, and specialty chemical industries seeking high-performance additives for PVC, synthetic rubbers, and other polymer systems.

Application

• Primary Plasticizer for PVC: Imparts excellent flexibility, low-temperature performance, and permanence in wire and cable insulation, automotive interiors, and flexible films.
• Co-Additive in Polymer Blends: Enhances the compatibility and processing characteristics of other plasticizers in complex formulations.
• Synthetic Rubber Compounding: Used as a processing aid and softener to improve the workability and elastic properties of various elastomers.
• Specialty Adhesives and Sealants: Provides lasting flexibility and adhesion in high-performance construction and industrial sealant applications.
• Coating Resins: Acts as a modifier to improve the film-forming properties, flexibility, and durability of industrial and protective coatings.
• Gasket and Hose Manufacturing: Contributes to the long-term resilience and resistance to fluid extraction in molded rubber goods.

Quality Control

Our Decyl Octyl Hydrogen Benzene-1,2,4-Tricarboxylate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and performance-critical physical properties. Certificates of Analysis (COA) documenting these results 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 away from strong acids 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 and contamination.
