Description

Decyl Nonyl Phthalate is a high-molecular-weight phthalate ester plasticizer, specifically a mixed ester of phthalic acid with decyl and nonyl alcohols. This compound is valued for its excellent compatibility with a wide range of polymers, providing enhanced flexibility, durability, and low-temperature performance to finished products. It is primarily needed by manufacturers in the plastics, polymer compounding, and specialty chemical industries seeking a versatile and efficient plasticizer for demanding applications.

Application

• Primary plasticizer for Polyvinyl Chloride (PVC) resins in wire & cable insulation, flooring, and synthetic leather.
• Key component in the formulation of high-performance polymer compounds requiring low volatility and migration resistance.
• Used in the production of adhesives, sealants, and coatings to improve flexibility and workability.
• Plasticizer for nitrocellulose and other specialty resins in industrial applications.
• Imparts low-temperature flexibility to elastomers and rubber products.
• Employed in the manufacture of gaskets, hoses, and other molded plastic goods.
