ABSTRACT:
A highly filled surface covering, preferably a floor covering and more preferably a floor tile, includes a resin layer which has about 80% to about 95% by weight of filler and a chlorine-free binder. The binder includes a mixture of a maleic anhydride grafted polyethylene and a substantially linear ethylene/octene copolymer. The ratio of maleic anhydride grafted polyethylene and ethylene/octene copolymer is from about 1:5 to about 1:15 by weight. The preferred formulation for the binder includes a solid tackifier selected from the group consisting of a hydrocarbon resin having an ester moiety and hydrogenated aromatic resin.
