,Product Performance and usage
PVC paste resins are one of the plastic materials of good physical and mechanical properties, good chemical stabilities and good transparency. Especially, its simple manufacturing method and small equipment investment give it a wide application area.
Widely applied to the production of PVC,vinyl chloride copolymer and cellulose resins,also can be used to make thin film,artificial,wire,cable,sheet,panel,molding,plasticized paste etc.
This product can also be used as the softener for synthetic rubber ,such as nitrilerubber,will improve the product's rebound resilience and decrease compresion set.
In addition is has no influence on the vulcanization of glue stock.
About 80% to 90% DOP are used to PVC industry the others used to rubber,recycled plastic,lubricants,binder,paint,macromolecule additives,softener for printing ink capacitor oil,play zcetic ethylene and PVDC etc.
