A composition and methods including the composition |
| abstract |
A method for making a polytetrafluoroethylene (PTFE) membrane comprising metal oxide(s), the method comprising the steps of: a) mixing a PTFE resin, a lubricating agent and a metal oxide wherein a weight of the lubricating agent comprises between 15 and 25 percent of a weight of the PTFE resin, wherein a weight of the metal oxide comprises up to 10 percent of the weight of the PTFE resin, and wherein the metal oxide has at least one dimension less than 100 nm: b) forming a pre-form comprising a mixture of the PTFE resin, the lubricating agent and the metal oxide: c) extruding the pre-form to form a tape: d) calendaring the tape to facilitate evaporation of the lubricating agent: e) tentering the tape through bi-axially stretching to form a membrane and f) sintering the membrane. Also claimed is a method of incorporating a metal oxide into a mixture comprising a PTFE resin and a lubricating agent, the method characterised by mixing in a V blender and wicking. Also claimed is a composition characterised by an isoparaffinic solvent and a metal oxide having a specific surface area. |
