Descriptions & Applications

Diisononyl phthalate (DINP) is a phthalate used as a plasticizer in e.g. food contact materials. DINP is typically a mixture of chemical compounds consisting of various isononyl esters of phthalic acid.
This product is a general primary plasticizer with fine performances. Mostly used in PVC, chlorethlene polymer, cellulose nitrate ,ethyl cellulose and synthetic rubber. Easily dissolved with PVC, As its volatility, migration and non-toxicity are superior to DOP, it can present products with good light resistance, heat resistance, degradation resistance and electrical insulation. This product is widely used in toy film, wires and cables owing to its excellent properties of water fastness, low toxicity, degradation resistance and electrical insulation.
