DOP is an important and general primary plasticizer, chiefly used in the processing of PVC resin and high polymers such as chemical resin, acetic acid resin, ABS resin, rubber and also in the production of lacquer, dyestuff and dispersant, etc.
DOP of general grade is widely used in the industry of plastic, rubber, oilpaint and emulsifying agent. PVC plasticized by it can be used in the manufacture of artificial leather, agricultural film, packaging material and cables, etc.
