teflon bushing PTFE Material Introduction

Teflon (polytetrafluoroethylene, PTFE) is a high performance polymer material ‌ with excellent resistance to chemical corrosion, high and low temperatures, non-stickiness, electrical insulation and biological inertness, and is widely used in chemical, electronic, medical, food processing and other fields.


Chemical stability ‌ : Teflon is hardly eroded by any chemical reagents, including strong acids (such as aqua regia), strong bases and organic solvents. It is one of the most corrosion-resistant materials known. ‌ ‌


Temperature range ‌ : Long-term operating temperature -196 ° C to 260 ° C, short-term high temperature 327 ° C, and remains flexible at low temperatures. ‌ ‌


Low coefficient of friction ‌ : The coefficient of surface friction is extremely low (0.04-0.1), the lowest among solid materials, and does not change with temperature. ‌ ‌


Electrical insulation ‌ : Low dielectric constant (2.0-2.1), high resistivity (10^16-10^18Ω·cm), suitable for insulation of high-frequency electronic components






Advantages of Custom White PTFE Bushing CNC Machined:


  • Ultra-Low Friction:
    Natural self-lubrication reduces energy loss and improves operational efficiency.

  • Exceptional Chemical Resistance:
    Impervious to strong acids, bases, solvents, and harsh industrial environments.

  • Extreme Temperature Stability:
    Maintains performance from -200°C to +260°C.

  • Zero Maintenance Operation:
    Maintenance-free design, no lubrication needed, reduces downtime risk.

  • Customization Capability:
    Rapid production of non-standard sizes and complex geometries.

  • Dual Insulation & Protection:
    Provides excellent electrical insulation and mechanical safeguarding.

FAQ




1Q: What tolerances can you achieve with CNC-machined PTFE bushings?

1A: Standard ±0.01mm, tighter tolerances available upon request.  


2Q: Are your virgin PTFE bushings compatible with food/pharmaceutical applications?

2A: Yes, 100% pure PTFE meets FDA and USP Class VI standards.  


3Q: How do you ensure chemical resistance for specific solvents?

4A: We provide chemical compatibility charts and can validate against your required agents.  


4Q: What’s the typical lead time for custom geometries?

4A: 3-5 days for standard specs; complex designs may require 7-10 days.  


5Q: Can these bushings handle high axial loads in rotary applications?

5A: Optimized for radial loads; axial performance depends on design – consult our engineers.
