1.Diisononyl Phthalate (DINP) is a general use high molecular weight PVC Plasticizer which provides a good balance of cost savings and properties. 2.DINP is a preferred replacement for DOP plasticizer, and is highly compatible with PVC and shows good permanence. 3.When compared to DOP, DINP has lower volatility, improved cold temperature flexibility, and better permanence in the final product. 4.The products produced by DINP have good water resistance and extraction resistance, low toxicity, aging resistance and excellent electrical insulation properties, so they are widely used in toy films, wires and cables.
