What is DINP in DINP Plasticizer?

Diisononyl phthalate (DINP) is a transparent oily liquid with a slight odor. This product is a general-purpose primary plasticizer with excellent performance. DINP plasticizer has good compatibility with PVC, and it will not precipitate even if it is used in large quantities; its volatility, migration, and non-toxicity are all better than DOP (dioctyl phthalate), which can endow the product with good light resistance, heat resistance, and aging resistance And electrical insulation performance, the overall performance is better than DOP. Because the products produced by this product have good water and extraction resistance, low toxicity, aging resistance and excellent electrical insulation performance, they are widely used in toy films, wires and cables.

Compared with DOP, DINP has larger molecular weight and longer carbon chain, so it has better aging performance, anti-migration performance, anti-extraction performance and higher high temperature resistance. Correspondingly, under the same conditions, the plasticizing effect of DINP is slightly worse than that of DOP. It is generally believed that DINP is more environmentally friendly than DOP.

DINP is superior in improving extrusion efficiency. Under typical extrusion processing conditions, DINP can reduce the melt viscosity of the compound more than DOP, which helps to reduce die pressure, reduce mechanical wear or increase extrusion productivity (up to 21%). This increase in productivity can It can be achieved without changing product formula and production process, without additional fixed investment, without additional energy consumption, and while maintaining product quality.

DINP is an oily liquid in normal state, insoluble in water. Tank trucks are generally used for transportation, and small batches are transported in iron drums or special plastic drums.

One of the main raw materials of DINP - isononyl alcohol (INA).
