ACTUAL DIMENSIONS - 11.75" x 35.75" (Due to cutting kerf width) NOTE: The thin sheets MAY BE WARPED / WAVY because this is a soft formable plastic. Thin sheets are skived. Weather and chemical resistant Very low coefficient of friction and stable at high temperatures Very low moisture absorption and an excellent electrical insulator Polytetrefluoroethylene (PTFE) - This soft formable fluoropolymer is often used in high temperature environments due to its stability at temperatures up to 500 degrees F. It has excellent electrical insulating properties and is both weather and chemical resistant.
