Patent number: 9908088Abstract: A hollow fiber membrane fluid transport device is disclosed wherein the fibers are comprised of Polytetrafluoroethylene (PTFE), and the potting materials are comprised of fluorocopolymer and or fluoroterpolymer based materials. The potting of the device utilizes a compressed chemically resistant fluorocopolymer and or fluoroterpolymer film, allows for ease of manufacture without destruction of the PTFE hollow fibers, with high packing densities, and without the processing complexity of pre-melting, extruding, or chemical crosslinking of any polymeric adhesives. Furthermore, the PTFE hollow fibers can be treated with a fluoropolymeric solvent solution before the chemically resistant film is applied to enhance the adhesion of the PTFE fiber to the film.Type: GrantFiled: August 12, 2013Date of Patent: March 6, 2018Assignee: Markel CorporationInventors: Robert E. Jerman, Cornelius Brown, Jr., Kenneth Donald Hobbs, Carlos Ruano, Charles Edward Wolanski
