Description

Diisohexyl Phthalate is a high-purity phthalate ester plasticizer known for its excellent compatibility and performance in polymer systems. Its primary value lies in providing enhanced flexibility, durability, and processability to a wide range of synthetic materials. This product is essential for manufacturers in the plastics, coatings, and specialty chemical industries seeking reliable and consistent plasticizer solutions.

Application

• Primary plasticizer for polyvinyl chloride (PVC) resins in flexible film, sheet, and cable applications.
• Key component in the formulation of synthetic rubbers and elastomers to improve low-temperature flexibility.
• Used as a solvent and carrier in specialty adhesives and sealants to control viscosity and drying time.
• Plasticizer for cellulose-based plastics and other polymer dispersions.
• Functional additive in industrial coatings and inks to enhance film formation and adhesion.
• Used in the production of gaskets, hoses, and other molded plastic goods.
