What is Diisononyl Phthalate?

Diisononyl Phthalate (DINP) is a high molecular weight phthalate plasticizer widely used in polyvinyl chloride (PVC) and other polymer applications. It is produced by esterification of phthalic anhydride with isononyl alcohol. DINP exhibits excellent plasticizing efficiency, low volatility, and good resistance to extraction by water and soapy solutions. The compound demonstrates good compatibility with PVC resins and provides durable, flexible products with enhanced performance characteristics.
