  • Patent number: 8075993
    Abstract: Unique PTFE fabric and laminate structures, and methods for making the same, are described. Particularly, the invention comprises a laminate of a fabric comprising a plurality of PTFE fibers overlapping at intersections, wherein at least a portion of the intersections have PTFE masses extending from at least one of the overlapping PTFE fibers, and which lock the overlapping PTFE fibers together, bonded to a membrane by at least said PTFE masses. Such reinforced membranes exhibit exceptionally high bond strength, a particularly valuable attribute in applications in which durability is important.

  • Patent number: 6143675
    Abstract: A porous composite laminate material comprises a layer (4) of expanded polytetrafluoroethylene (PTFE) membrane, and a layer (2) of non-expanded porous PTFE attached thereto. The non-expanded porous PTFE layer may be a sintered porous PTFE produced by sintering granular-type PTFE particles to form a porous integral network of interconnected particles; and may be produced in situ by spray application onto the membrane followed by baking. Modifiers including unsintered fine powder PTFE, thermoplastic fluorinated organic polymer, a low molecular weight PTFE and mixtures thereof may be included. The expanded PTFE membrane can be in sheet form or in the form of expanded PTFE fibres woven into a fabric. The laminate may be used for oiling and cleaning high temperature fuser rolls in a photocopying machine, or as a filter.

  • Patent number: 6019920
    Abstract: An aqueous dispersion of modified granular PTFE particles is sprayed or cast to form a sheet. The sheet is then dried and the modified granular particles fused together to form an open network of fused interconnected particles that define a tortuous network of voids through the sheet. It has been found that when the modified granular-type PTPE aqueous dispersions are employed, the resulting fused sheets are stronger than when the usual unmodified PTFE homopolymer of the granular-type is used.
