High-performance polymer material made by molding and turning processes from polytetrafluoroethylene (PTFE) plates. It withstands extreme temperatures (-180°C to 260°C), is corrosion-resistant, has a low friction coefficient and is non-stick, with excellent insulation properties and stability. Its applications are extensive, serving as industrial sealing parts, mechanical sliding components, lining for chemical equipment, and is also suitable for food processing, medical instruments, and insulation for electronic devices. It can accommodate a variety of stringent working conditions, making it a practical and stable engineering material.
