Uniaxially and Biaxially-Oriented Polytetrafluoroethylene Structures |
摘要 |
The subject invention relates to uniaxially-oriented extrudate and methods for processing the same utilizing colloidal size polytetrafluoroethylene resin particles. Still another aspect of the subject invention relates to the advantage of uniaxially paste extruding colloidal size PTFE particles and particularly micron size fillers and additive up to 90% by volume. Another aspect of the subject invention relates to biaxially-oriented PTFE compositions made from uniaxially-oriented paste extrudate of the invention in the hydrostatic pressure coalescible state. The subject invention also relates to methods for preparing porous biaxially-oriented PFTE compositions utilizing fugitive pore-forming materials and methods for forming shapes from the PTFE composition of the subject invention.
