Foamable polymer composition, useful for making floor coverings, wallpaper and synthetic leather, includes plasticizer and isononyl benzoate to reduce viscosity and gelling temperature
A foamable composition containing at least one polymer; at least one plasticizer; and optionally other additives, is novel in including isononyl benzoate as the alkyl benzoate component. The composition features the plasticizer at 40-100 parts weight) per 100 parts of the polymer. Isononyl benzoate is present at 5-95 wt.% with respect to the plasticizer. A foamable composition features: (A) one or more polymer, selected from polyvinyl chloride; poly(vinylidene chloride); chlorinated polyolefin; or copolymers of vinyl chloride with vinylidene chloride, vinyl acetate, vinyl propionate, vinyl butyrate, vinyl benzoate, (m)ethyl acrylate or butyl acrylate; (B) one or more plasticizer 40-100 parts (by weight) per 100 parts of (A); (C) optional additives; and (D) an alkyl benzoate 5-95 wt.% of with respect to (B), The composition is novel in featuring isononyl benzoate as the alkyl benzoate. Independent claims are included for: (1) a method for preparing products having a foamed polymer layer by applying the foamable composition to a carrier; foaming the composition (before or after application) and heat treatment of the foamed composition; and (2) products that include at least one foamed layer of the foamable composition.
