Teflon (PTFE) is a highly versatile fluoropolymer renowned for its exceptional properties, making it ideal for custom parts in demanding applications. Its key attributes include unmatched chemical resistance, extreme temperature stability (-260°C to +260°C), the lowest coefficient of friction among solid materials, and superior electrical insulation. These characteristics stem from its unique molecular structure with strong carbon-fluorine bonds, enabling performance where most materials fail. For purchasers, understanding these properties ensures optimal material selection for corrosion-resistant components, high-temperature seals, low-friction bearings, and insulating parts.
Key Points Explained:
-
Chemical Resistance
-
PTFE Teflon is virtually inert to all industrial chemicals, including strong acids (e.g., sulfuric, hydrochloric), bases, and solvents. This makes it perfect for:
- Chemical processing equipment (valves, gaskets)
- Laboratory apparatus exposed to aggressive reagents
- Semiconductor industry components where purity is critical
- Unlike metals or rubbers, it won’t corrode or degrade when exposed to harsh environments.

-
Temperature Stability
- Operates continuously from cryogenic (-260°C) to high-heat (260°C) conditions without losing structural integrity. Key for:
- Aerospace components (thermal shields, gaskets)
- Automotive under-the-hood parts
- Industrial ovens and hot-process equipment
- Briefly withstands peaks up to 300°C, outperforming most plastics.
- Operates continuously from cryogenic (-260°C) to high-heat (260°C) conditions without losing structural integrity. Key for:
-
Low Friction & Non-Stick
- Coefficient of friction (~0.05) is lower than polished steel, enabling:
- Self-lubricating bearings and slides
- Food processing equipment (conveyor belts, molds)
- Medical devices requiring smooth motion
- Non-stick properties reduce contamination risks and simplify cleaning.
- Coefficient of friction (~0.05) is lower than polished steel, enabling:
-
Electrical Insulation
- High dielectric strength (60 kV/mm) and resistance to arcing suit:
- Wire/cable insulation in high-voltage applications
- Circuit board components
- Antenna covers in corrosive environments
- Stable performance across wide frequency ranges.
- High dielectric strength (60 kV/mm) and resistance to arcing suit:
-
Mechanical Considerations
- While strong, PTFE has low creep resistance; designs often compensate with:
- Reinforced variants (glass-filled for stiffness)
- Thicker cross-sections in load-bearing parts
- Machinability allows precise custom shapes but requires specialized tooling.
- While strong, PTFE has low creep resistance; designs often compensate with:
For purchasers, balancing these properties against cost and alternatives (e.g., PFA for better formability) is crucial. Did you know PTFE’s non-reactivity also makes it biocompatible, enabling uses in implants? This quiet workhorse material continues to enable innovations from deep-sea cables to space exploration.
