PTFE (Polytetrefluoroethylene) Product Guide
Applications | Mechanical Data
Overview
PTFE is a soft, low friction fluoropolymer with oustanding chemical resistance and weathering resistance. Also known as Teflon, PTFE is so slippery that its the only known surface which a gecko cannot stick. PTFE's extreme slipperiness combined with its mechanical properties make it ideal for bearings, seales, and piston rings in mechanical applications. It is FDA/USDA compliant and also offers high temperature melting, flexibility, impact resistance, and performs well at temperatures as low as -100°F. PTFE is commonly used for seals, gaskets, scientific equipment, pump parts, semiconductor equipment, and insulation for wiring in aerospace and computer applications.
