  • POROUS PTFE MEMBRANE
    Publication number: 20220062806
    Abstract: A porous polytetrafluoroethylene (PTFE) membrane including a nonwoven web having a microstructure of substantially only microfibrils fused at crossover points, said membrane having a percent balance of orthogonal dimensions that is within 10%.
    Type: Application
    Filed: December 16, 2019
    Publication date: March 3, 2022
    Inventors: Anil Suthar, Richard Brandimarte, Robert J. Pannepacker, Jr., Stuti S. Rajgarhia
  • PTFE membrane
    Patent number: 9409132
    Abstract: A method for improving the dimensional stability of PTFE membranes by the application of elevated temperature and elevated pressure to a PTFE membrane. The process reduces and/or eliminates the relaxation stress normally associated with PTFE membranes made using previously existing methods.
    Type: Grant
    Filed: October 18, 2010
    Date of Patent: August 9, 2016
    Assignee: Donaldson Company, Inc.
    Inventors: Richard Brandimarte, Kirit Patel
  • Microporous membrane for flash distillation
    Patent number: 9108163
    Abstract: A microporous membrane for flash distillation comprising at least three layers having distinct properties is disclosed. Generally, the membranes contain outer layers of relatively small pore size, with an interior layer with relatively large pore size. The invention is also directed to a system for desalinization comprising a source of hot brine.

  • Microporous membrane with a stratified pore structure created in situ and process
    Publication number: 20020045041
    Abstract: A microporous membrane is described comprising at least two layers, wherein each layer is characterized by nodes interconnected by fibrils, the layers are bonded by means of plastic flow at temperatures below the melting point of either membrane material, and the pore architecture is formed in situ by an expansion process. A stratified microporous membrane is produced wherein the pore architecture of each layer may be discretely controlled. The article is useful for filtration and medical applications where a pore size gradient is required.
