METHOD OF PRODUCING POLYTETRAFLUOROETHYLENE GRANULES CONTAINING FILLER Russian patent published in 2010 - IPC C08J3/16 C08L27/18

Abstract RU 2401284 C2

FIELD: chemistry.

SUBSTANCE: method is realised through granulation by stirring in water in the presence of a liquid organic solvent which is partially soluble in water. A polytetrafluoroethylene emulsion is added, as well as a coagulant for coagulation of the polytetrafluoroethylene emulsion in form of a surface layer of polytetrafluoroethylene granules containing filler.

EFFECT: obtaining granules with high looseness with low separation of filler, which prevents release of the polytetrafluoroethylene emulsion into liquid wastes.
