Perth Teflon (PTFE) Machining

What is Teflon (PTFE)?

Teflon, or PTFE, is a versatile thermoplastic that we recommend because of its heat resistance and low friction.

 

Teflon or polytetrafluoroethylene (PTFE) is most widely known for its use in pots and pans. However, manufacturers also use the plastic for various industrial applications, including chemical storage and lining.

 

Teflon (PTFE) can also be filled with other materials or used as expanded PTFE.

 

Glass Filled PTFE

 

Improved creep and wear resistance at varying temperatures. Glass filled PTFE is also chemical stable.

​

Carbon Filled PTFE

 

Carbon filled PTFE has improved creep and wear resistance, is excellent in high-pressure environments, and has antistatic properties and the ability to be self-lubricating.

​

Bronze Filled PTFE

 

Bronze filled PTFE has very high creep resistance, thermal conductivity and wear resistance. The material is not suitable for electrical applications and has low chemical resistance.

Stainless Steel Filled PTFE

 

Stainless Steel Filled PTFE has high wear resistance and excellent strength and stability. This is evident even under extreme loads and high temperatures.

​

Expanded PTFE or ePTFE

 

Expanded PTFE can be used in environments of up to 260°C and is resistant to most chemicals. The material is also great for sealing uneven or worn surfaces.

Teflon Advantages and Disadvantages

Teflon or PTFE has high lubricity, and is resistant to chemicals and UV. 

 

Teflon’s main advantageous properties are:

 

  • Chemical resistance

  • Resistance to heat (high thermal stability and flame resistance)

  • Good dielectric properties (non-conductivity)

  • Low friction

  • Doesn’t age or become brittle

  • Can be finished smoothly

  • Water resistance (non-wetting)

  • Resistance to weathering (long-lasting)

  • Ability to be food grade

  • Affordability

What is Teflon Used For?

Teflon (PTFE) Examples and Applications

Teflon’s advantageous properties make it perfect for a variety of applications. 

 

Common Teflon applications include:

 

  • Chemical storage and transport

  • Mechanical seals (dynamic and static)

  • Gaskets and bearing pads

  • Packing pumps and valves

  • Electrical insulation

  • Expansion bellows or joints

  • Linings and coatings

  • Bearings and bushes

  • Specialised tubing and pipe
