POLYETRAFLUOROETHYLENE COMPOSITION, METHOD FOR PRODUCING THE SAME AND GRANULATED MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide an emulsion polymerized PTFE composition suitable for a molding process, a method for producing the same and a granulated product of the same. SOLUTION: This polytetrafluorethylene composition is a composition of the emulsion polymerized polytetrafluoroethlyene(PTFE) with a filler, and is characterized by having <=50% powder shape modification ratio, and the PTFE granulated product is obtained by granulating the above PTFE composition. The above composition is produced by ejecting high pressure water to a mixture of the above emulsion polymerized PTFE with the filler.
