Description

Diisodecyl Adipate (CAS NO 27178-16-1) is a high-performance, low-volatility diester plasticizer prized for its excellent permanence and compatibility with a wide range of polymers. Its primary value lies in providing superior low-temperature flexibility and resistance to extraction, ensuring long-term product durability. This makes it an essential component for manufacturers in the plastics, coatings, and specialty lubricant industries seeking reliable performance in demanding applications.

Application

• Primary plasticizer for polyvinyl chloride (PVC) and other polymers requiring excellent low-temperature flexibility.
• Key ingredient in high-performance, low-fogging automotive interior components such as dashboards and upholstery.
• Functional fluid and base stock for synthetic lubricants and high-temperature greases.
• Plasticizer for specialty adhesives, sealants, and caulks where migration resistance is critical.
• Additive in coatings and inks to improve flexibility and adhesion on flexible substrates.
• Processing aid and secondary plasticizer in wire and cable insulation compounds.
• Component in gasket and seal formulations for its stability and resistance to hydrocarbon fluids.

Quality Control

Our Diisodecyl Adipate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. Each lot is tested against rigorous internal specifications, which typically include parameters for appearance, color, acid value, ester content, and moisture. 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 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.
