て再生製品とする。In the present invention, in addition to the above-mentioned glass fibers and graphite, the inorganic fillers used include molybdenum disulfide, freon, mica, aluminum silicate, talc, metal oxides, etc., and the amount blended into the tetrafluoroethylene resin is as follows: It is usually 5 to 80% by weight. Waste material of tetraethylene ethylene resin containing inorganic filler is cut into pieces of rope. At this time, it is preferable to use a carbide tool for cutting. Heating is usually carried out by putting the shredded waste material into a mold and keeping the door open for a long time at a temperature of 327° C. or more and 420° C. or less until the temperature reaches a uniform temperature throughout the inside. Pressurization is performed by taking the mold out of the furnace and applying a pressure of about 80 kgf/cm2 to 150 kgf/cm2 to the mold for a short time when the melt viscosity of the first material reaches about 10 poise. This is done by After pressurization, the waste material is extruded from the mold or by other methods to obtain a molded product, which is slowly cooled or rapidly cooled and then annealed to produce a recycled product.
