PCTFE Bushing is a high-performance fluoropolymer component made from Polychlorotrifluoroethylene, specifically designed for use in high-precision mechanical systems. Thanks to its low coefficient of friction, excellent thermal stability, and resistance to chemicals and moisture, it is widely used in aerospace, cryogenic systems, precision instruments, and vacuum applications.
This material maintains tight dimensional tolerances and mechanical strength even in harsh operating conditions ranging from -200°C to +150°C, making it ideal for demanding applications requiring both smooth motion and long-term reliability.
