Performance
This product is a main plasticizer used mostly in plastic processing and has excellent comprehensive properties.
It is widely used in the processing of cellulose resin, and in the manufacture of thin films, artificial leather, wire and cable sheets, plates, mouldings, plasticizers, etc.
This product can also be used as a softener for synthetic rubber such as NBR. It can improve the resilience of products, reduce the compression permanent deformation, and has no effect on vulcanization of rubber.
80%~90% of DOP is used in the PVC industry. Others are used in rubber, recycled plastics, lubricants, adhesives, coatings, macromolecule additives, softeners for printing ink and capacitor oils.
