Description

Bis(2-Ethylhexyl)Isophthalate is a high-purity, high-molecular-weight diester plasticizer. This compound is valued for its excellent compatibility with a wide range of polymers, providing superior permanence and low volatility. It is a critical component for manufacturers in the plastics, coatings, and specialty chemical industries seeking to enhance the flexibility and durability of their products.

Application

• Primary plasticizer for polyvinyl chloride (PVC) resins in wire and cable insulation, flooring, and automotive interiors.
• Functional additive in specialty adhesives and sealants to improve flexibility and adhesion.
• Co-plasticizer in nitrocellulose and other synthetic resin-based coatings and inks.
• Processing aid for synthetic rubbers to enhance low-temperature properties.
• Component in high-performance lubricants and hydraulic fluids.
• Intermediate for the synthesis of other specialty esters and polymer modifiers.
