摘要： The present invention provides a method of manufacturing a polytetrafluoroethylene (PTFE) product offering better productivity and a higher degree of flexibility in form of the product to be obtained than the conventional methods of manufacturing a PTFE product, and a method of manufacturing PTFE particle aggregate obtained as an intermediate while manufacturing a PTFE product. According to the manufacturing methods, aggregate of PTFE particles including water and a surfactant is obtained by applying force to a dispersion of PTFE particles containing PTFE particles, a surfactant and water as a dispersion medium, where the force makes the PTFE particles approach or contact with each other. Such a manufacturing method may be carried out, for example, with a chamber (1) shown in FIG. 1.

摘要： Disclosed is a process for production of a polytetrafluoroethylene (PTFE) sheet, which is superior in productivity compared to conventional processes and can reduce the cost of production. Also disclosed is a process for production of a PTFE seal tape. The processes comprise the following steps (i) to (iii): (i) applying a force to a PTFE particle suspension comprising PTFE particles, a surfactant and water (a dispersion medium) so that the particles can come close to each other or contact with each other, thereby forming a PTFE-containing solid material having the water and the surfactant included therein; (ii) shaping the solid material into a sheet-like form; and (iii) reducing the water content in the sheet-like solid material.
