ABSTRACT:
The subject invention pertains to methods for processing polytetrafluoroethylene (PTFE) resin into highly desirable product forms that fill the needs of the fluoropolymer industry. The subject invention concerns methods for making a multi-directional planar oriented PTFE resin structure. PTFE produced by methods of the present invention will challenge or exceed the capabilities of melt processable resins and accomplish many of the goals not previously realized by the fluoropolymer industry. The subject invention also concerns methods for preparing PTFE resin primary colloidal particles. The subject invention also concerns the PTFE primary colloidal particles produced by the methods and products utilizing the particles.
