PTFE Rod (Teflon Rod) is a cylindrical material made of polytetrafluoroethylene, featuring excellent corrosion resistance (against strong acids, alkalis, and organic solvents), high/low-temperature tolerance (-200°C to +260°C), a low friction coefficient (0.04), and insulating properties. Pure PTFE rods are ideal for high-purity environments, while modified versions (e.g., glass fiber/graphite-filled) offer enhanced mechanical strength.
