  • Method of forming a molecularly polarized polmeric sheet into a non-planar shape
    Patent number: 4985195
    Abstract: A method for forming sheets of polarized PVDF into non-planar shaped bodies is described. The technique includes the steps of shaping the polymer material by disposing a sheet of the polymer material about a non-planar surface and subjecting the sheet of polymer material and said non-planar surface to an elevated temperature for a predetermined period of time until said non-planar shape is permanently imparted to the sheet of molecularly polarized polyvinylidenefluoride material.
