PVC processing aids 420
DZ-420 is a PVC processing aid with ultra-high molecular weight. It is mainly to promote the melting of PVC compounds, so that PVC products have good mechanical properties and surface quality. The advantages of using 420 are having faster plasticization and better melt fluidity. It is widely used in rigid PVC products, such as PVC profiles, PVC pipes, PVC pipe fittings, PVC foamed products, etc.
