Use of talc and pyrogenic silicon dioxides as dispersants in production of rigid polyvinyl chloride films filled with calcium carbonate

Abstract

The influence of dispersing agents (talc and hydrophilic silicon dioxides) on the physical and mechanical properties of rigid polyvinyl chloride (PVC) films filled with calcium carbonate is considered. Test results for tensile strength, elongation at break and impact strength were analyzed for film samples containing different ratios of dispersant and filler.
