Product Description of Diisononyl phthalate CAS#28553-12-0
Diisononyl phthalate (DINP) is a clear, oily liquid with a mild odor. It serves as a versatile primary plasticizer with outstanding performance characteristics. DINP is highly compatible with PVC, ensuring no precipitation even when used in large quantities. Compared to DOP, it offers improved volatility, migration resistance, and non-toxicity.
Additionally, it enhances the product's chemical stability, light resistance, heat resistance, aging resistance, and electrical insulation properties, making its overall performance superior to that of DOP. Due to its excellent water resistance, extraction resistance, low toxicity, aging resistance, and superior electrical insulation, DINP is widely used in the production of various soft and hard plastic products, toy films, wires, and cables.
