PTFE or polytetrafluoroethylene (Teflon™) is a soft, low friction fluoropolymer with outstanding chemical resistance and weathering resistance. PTFE is stable at temperatures up to 500ºF and it is often used in high temperature environments. PTFE also has excellent electrical insulating properties. PTFE Rod is extruded in all standard sizes from 1/8th inch diameter up to 4 inches in diameter. PTFE rod is generally used as machining stock for all kinds of chemical, electrical and mechanical components where the outstanding performance characteristics of PTFE are required.
