Abstract: A polyvinyl halide compound has thermal conductivity and includes polyvinyl halide resin, natural or synthetic graphite of flake or spheroid form, and at least 0.5 weight percent of epoxidized vegetable oil. Selection of types and amounts of graphite and epoxidized vegetable oil provide thermal conductivity while other desirable properties of the compound are suitably maintained. The compound can be used for making any end use article that needs flame retardance and good thermal management and is especially useful as a thermally conductive material to replace die cast or extruded aluminum heat sinks in industrial applications, such as LED lighting fixtures.
Abstract: A flame retardant, flexible polyvinyl chloride mixture includes a trio of plasticizers and molybdate-based smoke suppressant for use in wire and cable articles.

Abstract: A polyvinyl halide compound, alone or alloyed with thermoplastic polyurethane, is used as a flexible layer for over-molding a rigid polymer substrate. Selection of types and amounts of calcium carbonate for the overmolding layer improves peel strength to achieve cohesive failure of the flexible overmolding layer rather than adhesive failure of the interface between the flexible overmolding layer and the rigid polymer substrate.
