expanded PTFE sheetis manufactured by expanding 100% virgin PTFE that uses a
proprietary process to produce uniform and highly fibrillated
microstructure with equal tensile strength in all directions. The
resulting product exhibits characteristics significantly different
than conventional PTFE sheet.expanded PTFE sheetis much softer and more flexible than regular PTFE sheet, soexpanded PTFE sheetconforms easily to irregular and rough surfaces. In addition, the
material is easier to compress and minimizes creep and cold flow.
