Description

Diisoheptylphthalate is a high-purity phthalate ester plasticizer, specifically the diester of phthalic acid and isoheptyl alcohol. This compound is valued for its excellent solvating power and compatibility with a wide range of polymers, providing enhanced flexibility and durability to finished products. It is primarily sought by manufacturers in the plastics, coatings, and specialty chemical industries for formulating high-performance materials.

Application

• Primary plasticizer for PVC (polyvinyl chloride) resins in wire & cable insulation, flooring, and synthetic leather.
• Key component in the formulation of adhesives and sealants, improving bond strength and flexibility.
• Functional additive in paints, coatings, and inks to enhance film formation and elasticity.
• Processing aid and viscosity modifier in polymer and rubber compounds.
• Solvent and carrier in specialty industrial and chemical applications.
• Used in the production of flexible films and sheets for packaging and construction.
