Description

Isodecyl Isooctyl Phthalate is a high-performance, branched-chain phthalate ester plasticizer. This compound is valued for its excellent compatibility with a wide range of polymers, providing superior low-temperature flexibility and processing characteristics. It is primarily utilized in the formulation of flexible PVC and other polymer systems where durability and performance are critical. Industries such as wire and cable, automotive, and construction materials rely on its consistent quality for demanding applications.

Application

• Primary Plasticizer for Flexible PVC: Used in calendering, extrusion, and molding processes for films, sheets, and profiles.
• Wire and Cable Insulation: Imparts excellent electrical properties and long-term thermal stability to insulation and jacketing compounds.
• Automotive Interiors: Formulated into synthetic leather, dashboards, and other interior components requiring low fogging and good cold flexibility.
• Sealants and Adhesives: Acts as a processing aid and flexibilizer in various sealant and adhesive formulations.
• Coated Fabrics and Artificial Leather: Provides softness, durability, and a consistent hand feel to synthetic leather products.
• Printing Inks and Coatings: Used as a polymeric plasticizer to enhance flexibility and adhesion in specialty ink and coating systems.

Quality Control

Our Isodecyl Isooctyl Phthalate is manufactured under a strict quality management system to ensure batch-to-batch consistency and reliability. Each lot is tested against stringent internal specifications for key parameters such as purity, color, acidity, and ester content. While produced to industrial grade standards, we can discuss custom purity requirements. A comprehensive Certificate of Analysis (COA) is provided with every shipment to guarantee compliance with your specifications.

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 containers tightly sealed when not in use to minimize moisture absorption and contamination.
