PTFE, also known as Teflon, provides outstanding resistance to chemicals and has an unparalleled low coefficient of friction.
Polytetrafluoroethylene (PTFE), commonly known as Teflon, is a high-performance fluoropolymer widely used in CNC machining due to its exceptional properties. Renowned for its non-stick and ultra-low friction characteristics, PTFE is an ideal material for applications such as bearings, bushings, and seals, where minimal friction is essential.
PTFE also exhibits outstanding chemical resistance, allowing it to perform reliably in aggressive environments. With an extensive operating temperature range from -200°C to +260°C, it remains stable under extreme conditions. Additionally, its excellent electrical insulation capabilities make it a preferred choice for electronic components and insulation applications.
PTFE components are valued for their low friction and exceptional chemical resistance, making them ideal for industrial and electrical uses.
