CARPET OR CARPET TILE BACKING COMPOSITION AND PROCESS FOR ITS APPLICATION

摘要

An improved backing for carpet or carpet tiles is provided in which a bitumen is filled with a limestone-type filler. Carpet and carpet tiles incorporating the filled bitumen are cheaper to produce, less brittle and more fire resistant than conventional carpet or carpet tiles. Because of the nature of the filled bitumen when in a fluid state, the process for manufacturing carpet or carpet tiles of the invention differs from conventional processes.
