| CAS No. | 28553-12-0 |
| Type. | Plasticizer |
| Appearance | Transparent oily liquid |
| Molecular Formula | C26H42O4 |
Applications:
(1) As the main plasticizer, DINP is widely used in various kinds of soft PVC products. Such as wire and cable, film, PVC leather, PVC floor leather, toys, shoes, seals, sheaths, wigs, tablecloths, etc. DINP is also used in some rubber products and coatings.
(2) Compared with DOP, DINP has larger molecular weight and longer carbon chain. So it has better aging performance, migration resistance, extraction resistance, and 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.
