General-purpose flexible plastic products

Diisononyl phthalate (DINP for short) is a transparent oily liquid with a slight odor. This product is a general-purpose main plasticizer with excellent performance. This product has good compatibility with PVC and will not precipitate even if used in large quantities; its volatility, migration and non-toxicity are better than DOP, and it can give the product good light resistance, heat resistance, aging resistance and electrical insulation properties, and its comprehensive performance is better than DOP. Because the products produced by diisononyl phthalate have good water resistance and extraction resistance, low toxicity, aging resistance, and excellent electrical insulation properties, they are widely used in various soft and hard plastic products, toy films, wires, and cables.
