Polytetrafluoroethylene (Teflon®)
PTFE offers the lowest coefficient of friction of any solid material and outstanding chemical resistance. It operates across an extreme temperature range from -200°C to +260°C, making it essential for sealing and sliding applications.
PTFE (commonly known by the brand name Teflon®) is a fluoropolymer with exceptional properties. It is chemically inert to virtually all substances and has the lowest coefficient of friction of any known solid material.
Its unique non-stick properties, combined with excellent electrical insulation and broad temperature resistance, make PTFE indispensable in sealing, electrical, and chemical processing applications.
