Title

(EN) Antimicrobial and antiviral polymeric master batch, processes for producing polymeric material therefrom and products produced therefrom

Abstract

(EN)

A polymeric master batch for preparing an antimicrobal and antifungal and antiviral polymeric material comprising a slurry of thermoplastic resin, an antimicrobal and antifungal and antiviral agent consisting essentially of water insoluble particles of ionic copper oxide, a polymeric wax and an agent for occupying the charge of the ionic copper oxide.
