Functional Masterbatches

The functional masterbatch series are all inner addition products. Namely added in the polymeric resins before plasticization, during the plasticization process, the functional additives filter into the polymeric resins to realize the special functions.
Comparing with after finish method, the inner adding method can have easier processing, higher bonding force and longer effect etc. This method has been had a new trend in functional fiber area.

Packing: 25kg/bag, packing bag is a paper and plastic film compound bag, inner with a PE film bag.
