Dioctyl phthalate is a common plasticizer used in PVC resin processing, can also be used for the processing of synthetic resin, acetate resin, ABS resin, and rubber and other polymers can also be used in making paint, dye, dispersant.

General Purpose DOP: widely used in industries such as plastics, rubber, paint and emulsifier. Plasticized PVC can be used in the manufacture of artificial leather, agricultural film, packaging materials, cable, and so on.

Electrical grade DOP: a full performance of the generic class of DOP, but also has excellent electrical insulating properties, mainly for the production of wires and electricity.
Food-grade DOP: mainly used in the production of food packaging materials.
Medical grade DOP: mainly used in the production of health products, such as disposable medical devices and medical packaging materials.
