Abstract: A process for the recycling of a vinyl chloride polymer material which comprises an initial level of one or more additive compounds comprises providing an aqueous acid composition comprising one or more alcohols and one or more acids, contacting the vinyl chloride polymer material and a volume of the acid composition to cause extraction of the one or more additive compounds from the vinyl chloride polymer material, wherein the acid composition forms a two-phase system with the vinyl chloride polymer material, comprising a solid phase comprising a purified vinyl chloride polymer material and a liquid phase comprising the alcohol, the water, the acid and the extracted one or more additive compounds, and separating the solid phase comprising the purified vinyl chloride polymer material and the liquid phase comprising the extracted one or more additive compounds.

Abstract: A method for forming a fire-retardant thermoplastic composite panel includes mixing a thermoplastic polymer with a fire-retardant additive to form a fire-retardant polymer composition and assembling a composite layup of a plurality of first layers and a plurality of second layers by alternatingly positioning the plurality of first layers and the plurality of second layers with each first layer including a fire-retardant polymer composition film of the fire-retardant polymer composition and each second layer including a carbon-fiber fabric. The method further includes compression molding the composite layup to form the fire-retardant thermoplastic composite panel.
