Diisononyl Phthalate Uses

  1. Diisononyl phthalate is a general-purpose main plasticizer with exceptional performance. This product has excellent compatibility with PVC.
  2. Diisononyl phthalate low poisoning, maturing resistance as well as excellent electric insulation homes, they are widely made use of in numerous soft as well as tough plastic items, plaything films, cords and also cable televisions.

Diisononyl Phthalate Chemical Properties

The plasticizing residential properties of Diisononyl phthalate resemble DEHP, and Diisononyl phthalate is a general-purpose plasticizer Diisononyl phthalate has low volatility and reduced plasticizing performance. Compared to DEHP, it has reduced plasticizing performance, movement, water extraction price as well as slightly higher gelling temperature level and also digital resistance; its reduced volatility, not only can Extending item life likewise reduces evaporative emissions in the process.
