PROCESS FOR PRODUCING POROUS STRETCHED POLYTETRAFLUOROETHYLENE FILM OR TAPE HAVING CATALYST PARTICLES SUPPORTED THEREON, AND FILTER FOR OZONE REMOVAL |
摘要 |
<p>An improved method for producing an expanded polytetrafluoroethylene (PTFE) porous film or tape supporting catalyst particles. The method for producing an expanded PTFE porous film or tape supporting catalyst particles according to the invention comprises a step of preparing tape-like porous PTFE, a step of impregnating the tape-like porous PTFE with a solution or dispersion of catalyst particles, a step of substantially removing the solvent or dispersing medium, and a step of further stretching the tape-like porous PTFE containing the catalyst particles in the machine direction (MD) and/or the transverse direction (TD).</p> |
