摘要： PROBLEM TO BE SOLVED: To obtain a wide highly conductive PTFE sheet almost uniform in conductivity in a longitudinal direction in a lateral direction. SOLUTION: A highly conductive PTFE sheet is produced by extruding a PTFE pasty compd. containing a conductive substance and an extrusion aid to form an unbaked tubular extrudate 32, and cutting and opening the extrudate 32 at least at one place of the periphery thereof by a cutter 33 and, as necessary, further rolling this extrudate by rolling rolls 47, 48 to form a sheet. This highly conductive PTFE sheet may be further baked. This wide and long highly conductive PTFE sheet obtained by this method has a width of 170 mm or more and the change of the vol. resistivity (conductivity) in the longitudinal direction thereof in the lateral direction thereof is almost uniform within a range of 10% or less, pref., 7% or less.

摘要： PROBLEM TO BE SOLVED: To eliminate a problem concerning a handleability of a charge in molding while there is no inconvenience such as generation of a part in which thermoplastic resin is separated from reinforcing fiber or the like by a method wherein after melt extrusion of fiber reinforced thermoplastic resin destruction rubbish with a ram extruder, molding is executed with a mold. SOLUTION: After filling of a specific amount of fiber reinforced thermoplastic resin destruction rubbish from a hopper 11 of a melt ram extruder 1, a principal extrusion ram 9 is operated with a principal extrusion cylinder 6, and a specific amount of fiber reinforced thermoplastic resin destruction rubbish and/or end material of a stampable sheet are successively sent out into a plasticizing cylinder 2. A preset temperature of a first heating cylinder 2a-a fourth heating cylinder 2d of the plasticizing cylinder 2 is preferably 190-230 deg.C when, for example, the thermoplastic resin is polypropylene resin. The end material is plasticized in the plasticizing cylinder 2, passes a heated flange 3 as a melt, and pressed into a measuring cylinder 4. A specific amount of the melt is discharged from an inside of the measuring cylinder 4 into a specific mold.
