Description

Isononyl Octyl Phthalate is a high-performance, mixed-chain phthalate ester plasticizer. This compound is valued for its excellent compatibility with PVC and its ability to impart superior low-temperature flexibility and durability to polymer formulations. It is primarily used by manufacturers in the plastics, coatings, and sealants industries seeking to enhance the performance and longevity of their products.

Application

• Primary plasticizer for flexible Polyvinyl Chloride (PVC) applications, including wire & cable insulation, flooring, and synthetic leather.
• Key component in the formulation of adhesives and sealants to improve flexibility and adhesion.
• Used in the production of polymer coatings for enhanced weatherability and film formation.
• Plasticizer for rubber and elastomer compounds to modify processing and physical properties.
• Additive in printing inks and specialty coatings to adjust viscosity and performance.
• Used in the manufacture of gaskets, hoses, and other molded plastic goods requiring low-temperature performance.
