ABSTRACT:
PTFE is bonded directly to PTFE, and PTFE and related fluoropolymers are surface configured or molded, employing the differential expansion of the fluoropolymer to a confinement vessel or mold, and heating the same to fusion temperature and then cooling, creating a uniformly applied pressure on the polymer, followed by cooling while maintaining the pressure, at least during the initial cooling stages.
