摘要:
A process is provided for manufacturing a composite of a sheet of expanded, porous polytetrafluoroethylene (PTFE) impregnated with another resin, the other resin being impregnated within the pores of the expanded PTFE. The other resin imparts desired characteristics to the composite such as high thermal resistance and low dielectric constant which make it useful as substrates for printed circuit boards. The composite is useful as a dielectric generally and as an adhesive.

摘要:
A sheet material is obtained by adhesion-laminating a porous polytetrafluoroethylene film on to a gas-permeable resin layer. A hydrophilic resin layer can be applied to the opposite surface of the porous polytetrafluoroethylene or between the latter and the gas-permeable layer. Such materials exhibit both waterproof and water vapour-permeable properties, resulting from the porous polytetrafluoroethylene film or hydrophilic resin layer, and are reinforced, and provided, if desired, with artificial leather ornamentation by the gas-permeable resin layer. Accordingly, gloves or other garments, manufactured using such materials, are waterproof and water vapour-permeable and are comfortable to wear since internal condensation is avoided.
