PTFE Irregular Shaped Parts​ are custom-processed non-standard components made from polytetrafluoroethylene (PTFE) raw material, specifically designed for extreme working conditions. Key characteristics include:

• ​Corrosion resistance: Resistant to strong acids (e.g., aqua regia, hydrofluoric acid), strong alkalis, and organic solvents;
• ​Wide temperature stability: Operating temperature range from ​​-200°C to 260°C, with short-term tolerance up to ​300°C;
• ​Self-lubricating and anti-stick: Friction coefficient as low as ​0.04–0.15, maintenance-free;
• ​Insulation and anti-aging: High dielectric strength (10kV/mm), weather resistance.
  Primarily applied in ​chemical seals, ​mechanical bearing bushings, ​semiconductor insulation components, and ​medical device assemblies, addressing sealing, insulation, and corrosion resistance needs in complex environments.
