DINP (phthalate nonyl ester) is composed of benzene anhydride and nonyl alcohol esterification reaction and the commonly used plasticizer。
CAS no. : 68515-48-0 formula: C26H4204 molecular weight: 418. 61
Alias: raised plastic agent DINP, adjacent phthalate different nonyl ester, 1, 2 - benzene dicarboxylic acid two different nonyl ester.

Phthalate different nonyl ester or DINP a transparent oily liquid, there was a slight smell good performance of the product is universal primary rights agent. This product with good intermiscibility, PVC does not precipitate heavy use; Volatile, mobility, non-toxic were superior to D0P (phthalic acid dioctyl ester), can gift products good light resistance, heat resistance, aging resistance and electric insulation performance, comprehensive performance is better than that of D0P. Because this product in the production of products with good resistance to water extraction resistance, low toxicity, aging resistance, good electrical insulating properties, therefore in the toy membrane, is widely used in wire and cable.
DINP compared with D0P, the larger molecular weight, the carbon chain is longer, so had better aging resistance, migration resistance, higher extraction resistance and high temperature resistant performance. Accordingly, under the same conditions, DINP plasticizing effect than D0P slightly worse. It is generally believed that DINP than D0P more environmentally friendly.
