    摘要: Thermoplastic compositions are disclosed which are useful as backings for automotive carpets. The thermoplastic compositions contain a high filler content of at least 60 percent by weight, about 5 to 25 percent by weight of an ethylene homopolymer or copolymer, about 1 to 10 percent by weight of a non-vulcanized elastomeric resin and about 1 to 15 percent by weight of a plasticizer. Preferably a low viscosity precoat of polyethylene or ethylene/vinyl acetate copolymer is applied to the carpet prior to the application of the thermoplastic backing. The backed automotive carpet is moldable, withstands both high and low temperatures, possesses outstanding sound absorbing properties and can be produced economically.
