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.

摘要： The present invention provides a water-proof sound-transmitting membrane including a polytetrafluoroethylene (PTFE) porous membrane, in which the waterproofness is enhanced further with little lowering of the sound transmittance. The water-proof sound-transmitting membrane includes the PTFE porous membrane. The PTFE porous membrane includes a first porous layer, and a second porous layer stacked on and integrated with the first porous layer by a binding force acting between PTFE matrices. The first porous layer and the second porous layer each are composed of PTFE with a number-average molecular weight of 5.0×107 or more determined by a standard specific gravity method. At least one layer selected from the first porous layer and the second porous layer has an average pore diameter of 1 μm or less. The water-proof sound-transmitting membrane has a surface density of 1 g/m2 to 10 g/m2.

摘要： Provided is a porous polytetrafluoroethylene (PTFE) membrane having a PF value of 36 or more and a mass per unit area of 0.90 g/m2 or less. The PF value is determined by the following equation: PF value={−log(PT (%)/100)/(PL(Pa)/9.8)}×100. PT (permeability) is determined by PT (%)=100−CE (%), CE (collection efficiency) is determined by a value measured using dioctyl phthalate particles with a particle diameter of 0.10 μm to 0.20 μm under a condition of a permeate flow rate of 5.3 cm/sec, and PL (pressure loss) is determined by a value measured under a condition of a permeate flow rate of 5.3 cm/sec. This porous PTFE membrane is suitable for air filter media.
