Polytetrafluoroethylene (PTFE)
Description (definition)
Polytetrafluoroethylene (PTFE), better known under the brand name Teflon®, is a high-performance thermoplastic material with exceptional chemical resistance, low friction and high temperature resistance. PTFE is hydrophobic, non-sticky and can be used in a temperature range from -200 °C to +260 °C. It is frequently used in the chemical, automotive, electrical and household appliance industries.
Example
A well-known example is the use of PTFE as a non-stick coating for pans and cookware. Its chemical stability and low friction make it ideal for use in the kitchen.
How is PTFE used in the automotive industry?
In the automotive industry, PTFE is used in seals, hoses and bearings. Its low friction and heat resistance ensure a long service life and reliable performance, especially in engines and gearboxes.
Why is PTFE important in the electrical industry?
PTFE is used in the electrical industry for cable insulation and components as it has excellent electrical insulating properties and high temperature resistance. It is particularly suitable for high-frequency applications.
Is PTFE recyclable?
PTFE is technically recyclable, but the recycling process requires special procedures. As a rule, recycled PTFE is used in applications that place lower demands on material quality, such as fillers or sealing products.
