Abstract

Self-supporting plastic film containing nonfibrous particles of an abrasive of particle size 0.005 to 0.10 inch may be used as substitutes for sand or emery paper. Plastics and abrasives specified are polyolefines, polyesters and polyamides and powdered glass, silicon carbide and alumina.ALSO:Striking surfaces of matchboxes are made from self-supporting plastic film containing non-fibrous particles of an abrasive of particle size 0.005 to 0.10 inch (see Divisions B5 or C4). Plastics and abrasives specified are polyolefines, polyesters and polyamides and powdered glass, silicon carbide and alumina.ALSO:Compositions for making self-supporting abrasive films (see Division B5 or C4) comprise a film-forming thermoplast and a non-fibrous abrasive of particle size 0.005 to 0.10 inch. Specified thermoplasts are polyolefines, e.g. polymers of propylene, ethylene and 4-methylpentane-1 and block copolymers thereof; polyesters; and polyamides. Specified abrasives are powdered glass, silicon carbide and alumina.
