PTFE ROD

PTFE Rod is a strong choice where the finished component needs very low friction, excellent chemical resistance, electrical insulation or performance across a broad temperature range.

It is particularly useful for seals, bushes, bearings, spacers, insulators and components exposed to aggressive chemicals or demanding operating conditions.

PTFE is softer and less rigid than engineering plastics such as Acetal or PEEK, so another material may be preferable where high stiffness, dimensional rigidity or heavy mechanical loading is the main requirement.

• Extremely low friction — excellent for sliding, bearing and sealing applications.
• Excellent chemical resistance — resistant to many chemicals and solvents.
• Wide temperature capability — useful across a broad range of demanding operating conditions.
• Excellent electrical insulation — useful for electrical and electronic components.
• Very low moisture absorption — useful in wet and moisture-exposed environments.
• Non-stick surface characteristics — useful where materials should release easily from the component.

PTFE Rod is commonly machined into:

• Seals
• Bushes and bushings
• Bearings
• Spacers
• Electrical insulators
• Valve components
• Pump components
• Gaskets and sealing components
• Low-friction guides
• Chemical-processing components
• General precision-machined parts

PTFE has one of the lowest coefficients of friction among commonly used solid engineering materials.

This makes it particularly useful where components slide against another surface or where reduced friction is important, including bushes, bearings, guides and sealing components.

PTFE can often operate with little or no additional lubrication, depending on the load, speed, temperature and application.

PTFE is well known for its excellent resistance to a very broad range of chemicals and solvents, making it valuable in chemical processing and other demanding environments.

Chemical suitability still depends on the specific chemical, concentration, temperature, pressure and service conditions.

Where chemical compatibility is critical, confirm suitability for the exact operating environment before selecting the material.

PTFE is commonly used across a very broad temperature range, approximately −200°C to +260°C.

This makes PTFE attractive for components operating at temperatures well outside the normal range of many common engineering plastics.

Actual allowable service conditions depend on load, duration, geometry and the mechanical requirements of the component, so the temperature figure should not be treated as a guarantee of mechanical performance at every temperature.

PTFE is an excellent electrical insulator and is widely used where high electrical resistance and stable dielectric performance are required.

This can make PTFE suitable for insulating bushes, spacers, supports and other machined electrical components.

PTFE can be turned, milled, drilled and bored using conventional machining equipment and suitable sharp tooling.

Because PTFE is relatively soft and flexible compared with materials such as Acetal, careful workholding, sharp tools and appropriate machining practices help achieve better dimensional accuracy and surface finish.

PTFE also has significant thermal expansion, so temperature and material movement should be considered when machining close-tolerance components.

PTFE is the generic material name for polytetrafluoroethylene.

Teflon™ is a well-known trademark used for particular fluoropolymer products. The term is sometimes used informally when referring to PTFE, but generic PTFE should not automatically be represented as branded Teflon™ material.

Engineering plastic rod is supplied as machining stock. Where a precise finished diameter or tolerance is required, allow sufficient material for machining to the final dimension.

PTFE has an extremely low-energy, non-stick surface and is difficult to bond using conventional adhesives.

Special surface treatments and specialised adhesive systems may be required where bonding is necessary.

Mechanical fastening or an alternative joining method may be more practical depending on the application.

PTFE is exceptional for low friction, chemical resistance and temperature capability, but another engineering plastic may perform better where stiffness, strength or dimensional stability are the priority.
