Polyvinyl chloride (PVC) due to their excellent chemical and physical properties as the lowest cost, one of the most common resin. PVC can be used main processing all kinds of processing, for example, mixing, extrusion, injection molding and blow molding.
The thermal decomposition temperature of PVC is close to its processing temperature. Therefore, it is necessary to add thermal stabilizers, plasticizers, impact modifiers and processing auxiliaries.
PVC processing performance is not very good, processing aids is very unique,only a small amount of addition can greatly improve the processing performance of PVC.
