ABSTRACT OF THE DISCLOSURE A mineral-filled thermoplastic composition is disclosed which comprises polyethylene or an ethylene-vinyl acetate copolymer; a mineral filler consisting, in the case of polyethylene, of alumina trihydrate, magnesia hydrate, calcium carbonate or calcium/magnesium carbonates, and, in the case of the ethylene-vinyl acetate copolymer, barium titanite or neodymium titanate; and, in the case of polyethylene, an impact promoter consisting of tri(2-ethylhexyl) phosphate, isostearic acid or dodecylpyridinium salts, the selection of the impact promoter being dependent upon the mineral filler being employed, and, in the case of the ethylene-vinyl acetate copolymer, an amount of isostearic acid sufficient to increase the ductility of the composition; also disclosed is an additive composition for a thermoplastic composition which comprises a hydrophobic agent and an impact promoter.
