PTFE Mechanical Parts​ are precision-engineered components manufactured using polytetrafluoroethylene (PTFE) as the core material, specifically designed for extreme working conditions. Key characteristics include:

• ​Corrosion Resistance: Withstands strong acids (e.g., aqua regia, hydrofluoric acid), strong alkalis, and organic solvents, exhibiting exceptional chemical stability.
• ​Temperature Resistance: Operating temperature range from ​​-200°C to 260°C, with short-term tolerance up to ​300°C.
• ​Self-Lubrication and Low Friction: Friction coefficient as low as ​0.04–0.15, requiring no additional lubrication and preventing adhesion.
• ​Electrical Insulation: High dielectric strength (approx. ​19.7 kV/mm), ensuring safe operation in high-voltage environments.
  Primarily applied in ​chemical seals, ​bearing bushings, ​semiconductor insulation components, and ​valve assemblies​ to resolve wear and leakage issues caused by high temperatures and corrosion, enhancing mechanical system reliability and lifespan.
