Technical Characteristics Supplement
1.Low Friction
Friction coefficient as low as 0.04, enabling operation without lubricants (metal gears require lubrication)
2.Corrosion Resistance
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
FieldSpecific Equipment CasesPerformance 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
