Description

Diisopentyl Phthalate is a high-purity phthalate ester plasticizer known for its excellent solvating power and compatibility with a wide range of polymers. This compound is valued for its ability to impart flexibility, durability, and low-temperature performance to various synthetic materials. It serves as a critical additive for manufacturers in the plastics, coatings, and specialty chemical industries seeking reliable performance and consistent quality in their formulations.

Application

• Primary Plasticizer for polyvinyl chloride (PVC), polyvinyl acetate (PVAc), and other synthetic resins to enhance flexibility and workability.
• Coating and Adhesive Formulations, where it acts as a film-forming agent and improves adhesion and elasticity.
• Specialty Chemical Intermediate in the synthesis of more complex esters, lubricants, and functional fluids.
• Sealant and Caulk Production, providing lasting plasticity and resistance to extraction.
• Printing Inks and Dyes as a solvent and carrier to control viscosity and drying time.
• Textile and Leather Auxiliary agent to soften finishes and coatings.

Quality Control

Our Diisopentyl Phthalate 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 identity confirmation, assay, color, acidity, and moisture content. A Certificate of Analysis (COA) documenting 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 acids and oxidizing agents. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use to minimize moisture absorption and contamination.
