Withstands highly corrosive media including ​98% sulfuric acid​ and ​liquid chlorine, with service life exceeding ​20,000 hours
3.Temperature Adaptability​
Operating range: ​​-200°C to +260°C​ (applications include aerospace liquid oxygen sealing)
​4.Reinforcement Modifications​
​Glass Fiber Filling: Increases compressive strength by ​300%​​ (e.g., 25% GF-PTFE)6
.
​Carbon Fiber Filling: Reduces wear rate to ​10⁻⁷ mm³/Nm​ (suitable for semiconductor equipment)
Typical Application Scenarios
Field​​Specific Equipment Cases​​Performance Advantages
Chemical Equipment​ Gear flow meters, corrosive fluid pumps Acid/alkali resistance, zero contamination 
​Food & Pharmaceuticals Filling equipment gears, sterile transfer systems FDA compliance, non-toxicity 
​Semiconductor Manufacturing​ High-purity chemical delivery pump gears Ultra-low particle release 
​Aerospace​ Liquid oxygen pump gears, vacuum chamber drive components Cryogenic resistance (-196°C) 
Key Technical Notes​
​Friction Performance: PTFE's ultra-low friction (0.04) stems from its smooth molecular structure, outperforming metals and common polymers
​Chemical Stability: Inert C-F bonds provide immunity to 98% H₂SO₄, aqua regia, and halogens
​Cryogenic Reliability: Maintains ductility at -196°C (liquid nitrogen), critical for rocket propulsion systems
​Enhanced Wear Resistance: Carbon fiber filling reduces abrasive wear by 90% in semiconductor pumps
