Di-n-octyl phthalate (DOP)

This product is a general-purpose plasticizer, appearing as a transparent oily liquid with no visible impurities. It is primarily used in the processing of polyvinyl chloride (PVC) resin, as well as in the processing of high polymers such as chemical fiber resin, acetate resin, ABS resin, and rubber. It can also be used in paint manufacturing, dyes, dispersants, etc. PVC plasticized with DOP can be used to produce artificial leather, agricultural films, packaging materials, cables, and more.

General-grade DOP is widely used in industries such as plastics, rubber, paints, and emulsifiers. PVC plasticized with it can be used to manufacture artificial leather, agricultural films, packaging materials, cables, etc.

Electrical-grade DOP possesses all the properties of general-grade DOP and additionally offers excellent electrical insulation performance. It is mainly used in the production of wires and cables.
