Fluoroplastic
PTFE / Teflon
Total chemical inertness & non-stick
PTFE (polytetrafluoroethylene), better known as Teflon®, is a high-performance thermoplastic known for its exceptional chemical resistance and very low coefficient of friction. It withstands continuous service temperatures up to 260 °C and offers excellent electrical insulation and remarkable resistance to ageing. PTFE is ideal for seals, bushings, valve seats, guides, sliding parts and components for the chemical, food, pharmaceutical, electrical and mechanical industries, where reliability and durability are essential.
