Products Description of Diisononyl Phthalate CAS#28553-12-0
Diisononyl phthalate (DINP) is a transparent, oily liquid with a slight odor. It is a high-performance general-purpose primary plasticizer widely used in plastic processing applications. DINP exhibits excellent compatibility with PVC and remains stable without precipitation even at high addition levels. Compared with DOP, it features lower volatility, reduced migration, and better safety performance, while providing plastic products with enhanced light resistance, heat resistance, aging resistance, and electrical insulation properties.
Due to its excellent water resistance, extraction resistance, low toxicity, aging resistance, and outstanding electrical insulation performance, DINP is widely applied in the production of various soft and rigid plastic products, including toy films, wires, and cables.
