SUSTAINABLE POLY(VINYL CHLORIDE) MIXTURES FOR FLOORING PRODUCTS

摘要

A mixture of poly(vinyl chloride) and epoxidized methyl soyate is disclosed. The epoxidized methyl soyate as a plasticizer replaces butyl benzyl phthalate which is conventionally used for the manufacture of multi-layer laminate sheet flooring or single layer tile flooring. The epoxidized methyl soyate, a bio-plasticizer, unexpectedly is a "drop-in" replacement for the butyl benzyl phthalate, both in terms of processing and performance. Also poly(vinyl chloride) - epoxidized methyl soyate mixtures have much better heat stability than poly(vinyl chloride) - butyl benzyl phthalate mixtures.
