Uses: Diisononyl phthalate (DINP for short) is a transparent oily liquid with a slight odor. This product is a general-purpose primary 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 all better than DOP, and it can give the product good chemical book light resistance, heat resistance, aging resistance and electrical insulation performance, and its comprehensive performance is better than DOP. Since the products produced by diisononyl phthalate have good water resistance and extraction resistance, low toxicity, aging resistance, and excellent electrical insulation performance, they are widely used in various soft and hard plastic products, toy films, wires, and cables.
