Abstract
An asbestos free composition suitable for the manufacture of vinyl floor tile comprises a substantially uniform mixture of a minor portion of vinyl polymer resin and a major portion of mineral filler consisting essentially of calcium carbonate and Kaolin clay. Formulations using such a mineral filler have been found processible into floor tile using the same basic production equipment and process line used in the manufacture of vinyl asbestos tile.
