Jeffery B Bowman, Daniel E Hubis, James D Lewis, Stephen C Newman, Richard A Staley: Process for producing a high strength porous polytetrafluoroethylene product having a coarse microstructure. W L Gore & Associates, Finnegan Henderson Farabow Garrett & Dunner, November 13, 1984: US04482516 (212 worldwide citation)

Porous polytetrafluoroethylene materials having high strength and coarse microstructure are produced by densifying the materials after removal of lubricant and then stretching. The term, "coarse," is used to indicate that the nodes are larger, the fibrils are longer, and the effective pore size is l ...
