In order to improve the performance of PTFE, the modified polytetrafluoroethylene, filled by carbon materials and aramid fiber with different scales, is prepared through the compression and sintering. A series of polytetrafluoroethylene (PTFE) fibers were manufactured by three processing methods including extrusion process, split-sheet process and split-film process. 7 to 6 times thicker than those for the commercial PTFE flat-sheet membranes. Propiedades de las membranas arquitectónicas: Translucidez; DurabilidadEl caucho silicona es un material que posee como principal propiedad la resistencia a la temperatura.
