Description

Hexyl Octyl Phthalate is a high-molecular-weight phthalate ester plasticizer known for its excellent performance characteristics. This compound is valued for its ability to impart superior flexibility, durability, and low-temperature properties to polymer matrices. It is primarily sought by manufacturers in the plastics, coatings, and specialty chemical industries for formulating high-performance products requiring enhanced plasticization and compatibility.

Application

• Primary plasticizer for PVC (polyvinyl chloride) resins in wire and cable insulation, flooring, and synthetic leather.
• Key component in the formulation of adhesives and sealants to improve flexibility and adhesion.
• Used as a processing aid and plasticizer in various elastomers and synthetic rubbers.
• Functional additive in paints, coatings, and inks to enhance film formation and durability.
• Plasticizing agent for cellulose-based plastics and other specialty polymer applications.
• Intermediate in the synthesis of other specialty esters and chemical compounds.

Quality Control

Our Hexyl Octyl Phthalate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, color, acidity, and other critical parameters. A Certificate of Analysis (COA) is provided with every shipment, and our quality protocols support compliance with relevant industry and regulatory standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong acids, oxidizing agents, and heat sources. 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.
