MACROSCOPICALLY PERFORATED POROUS POLYTETRAFLUOROETHYLENE MATERIALS |
摘要 |
<p>A macroscopically perforated porous expanded polytetrafluoroethylene sheet material having a microstructure of nodes interconnected by fibrils wherein the perforations have a minimum diameter of about 0.1 mm and wherein the orientation of a fibril varies as a function of the proximity of a fibril to the edge of a perforation. The length of the fibrils may also vary as a function of the proximity of a fibril to the edge of a perforation. The sheet material may be provided in a tubular form.</p> |
