ZUSAMMENGESETZTER POLYTETRAFLUORETHYLEN-GEGENSTAND UND VERFAHREN ZU SEINER HERSTELLUNG |
摘要 |
<p>A porous polytetrafluoroethylene (PTFE) article which is made up of a number of smaller articles with a microstructure of nodes interconnected by fibrils, these articles having been joined to one another such that their microstructure is virtually unaltered across the join. A process for producing such a PTFE article by closely abutting small-shaped PTFE segments and applying a force perpendicular to the seam while heating to a temperature above the crystalline melt point of the segments.</p> |
