MODIFIED POLYTETRAFLUOROETHYLENE FINE POWDER, METHOD FOR PRODUCING SAME, AND ELECTRIC WIRE AND TUBE EACH PRODUCED USING SAME

摘要

The purpose of the present invention is to optimize the primary particle diameters of a modified PTFE fine powder to shorten a burning time during molding. A non-melt-moldable modified polytetrafluoroethylene fine powder comprising a unit derived from tetrafluoroethylene, a unit derived from hexafluoropropylene, a unit derived from a perfluoro(alkyl vinyl ether) represented by CF2=CFO-CnF2n+1 (wherein n represents 1 to 6) and a unit derived from a (perfluoroalkyl)ethylene represented by CH2=CH-CmF2m+1 (wherein m represents 3 to 7).
