High-performance polymer material made by molding and turning processes, such as PTFE boards. It withstands extreme temperatures (-180℃ to 260℃), is corrosion-resistant, has a low coefficient of friction and is non-stick, and exhibits strong insulation and stability. Its applications are extensive, serving as industrial sealing parts, mechanical sliding components, lining for chemical equipment, and also suitable for food processing, medical instruments, and insulation for electronic devices. It is capable of adapting to various stringent working conditions, making it a practical and stable engineering material.
