Description

Dioctyl Adipate CAS NO 123-79-5 is a high-purity, low-volatility diester plasticizer derived from adipic acid and 2-ethylhexanol. This compound is valued for its excellent compatibility with a wide range of polymers, providing superior flexibility and low-temperature performance. It is a critical material for manufacturers in the plastics, coatings, and specialty chemical industries seeking reliable and efficient plasticizing solutions.

Application

• Primary plasticizer for Polyvinyl Chloride (PVC), imparting flexibility and durability to films, cables, and synthetic leather.
• Key component in nitrocellulose and synthetic rubber formulations, enhancing processability and final product resilience.
• Used as a functional additive in adhesives and sealants to improve low-temperature flexibility and adhesion.
• Employed in the production of food-contact compliant materials and packaging where specific migration limits are a concern.
• Acts as a lubricant and processing aid in various polymer compounding operations.
• Utilized as a solvent or carrier in specialty inks, coatings, and cosmetic formulations.
