Description

Isodecyl Isoundecyl Phthalate is a high-performance, branched-chain phthalate plasticizer. This compound is valued for its excellent low-temperature flexibility and permanence, making it a superior choice for demanding polymer applications. It is primarily used by manufacturers in the plastics, coatings, and specialty chemical industries seeking durable and versatile plasticizing solutions.

Application

• Primary Plasticizer for PVC: Imparts excellent flexibility, low-temperature performance, and durability to PVC compounds for wire & cable insulation, automotive interiors, and synthetic leather.
• Specialty Polymer Formulations: Used in nitrile rubber (NBR), polyurethane (PU), and other elastomers to enhance processability and final product properties.
• Adhesives and Sealants: Acts as a plasticizer to improve the flexibility, adhesion, and longevity of industrial and construction adhesives.
• Coating Resins: Incorporated into polyvinyl butyral (PVB) and other coating systems to improve film formation and elasticity.
• Gasket and Hose Manufacturing: Provides lasting flexibility and resistance to extraction in rubber gaskets, hoses, and other molded goods.
• Masterbatch and Compound Production: Serves as a key component in color and additive masterbatches for uniform dispersion in polymer matrices.
