Abstract

A procedure for preparing an essentially fine powder-free composition, characterized in that a normally fine powdery, powdery material, other than a polytetrafluoroethylene resin is mixed with fibrillating polytetrafluoroethylene resin and the mixture is worked until a crosslink has been formed at random from polytetrafluoroethylene fibers, and because the treated and worked material is recovered in a non-fine powder form.
