Patent number: 6127486Abstract: Microporous PTFE (ePTFE) is known to possess certain properties based on which it is excellently suited for specific purposes, for example, the material is air-permeable and water vapor-permeable, but not water-permeable so that it can be used for filter membranes, etc. In order to create additional functions and application possibilities for this material, a material is proposed that consists of a blend of a fluoropolymer and a thermoplastic. The two substances in the material are present as continuous structures, in which at least one of these structures, preferably both structures, are microporous. The two structures are intertwined with each other and form a so-called co-continuous macrostructure.Type: GrantFiled: September 11, 1998Date of Patent: October 3, 2000Assignee: W. L.
