PTFE (Teflon®)

Plastic

PTFE, better known by the brand name Teflon®, is a plastic distinguished by its exceptional chemical resistance and extremely low coefficient of friction. Thanks to its high temperature resistance and excellent insulating properties, PTFE is ideal for demanding environments. Moreover, the material is non-stick, making it widely used in technical applications where an anti-adhesion effect is required.
Well-known trade names for PTFE include Teflon®, Dyneon™, Fluon®, and Hostaflon®. These variants are used worldwide for their reliable performance in industry.

Properties of PTFE

Very high chemical resistance to almost all substances
Temperature resistant from –200 °C to +260 °C
Extremely low coefficient of friction (smooth surface)
Excellent electrical insulator
Non-stick and hydrophobic surface
UV and weather resistant, ideal for outdoor use
UV and weather resistant, ideal for outdoor use
Low mechanical strength (but compensatable with fillers)
Resistant to microbiological attack and aging

Thanks to this unique combination of properties, PTFE is popular in sectors where reliability under extreme conditions is essential. For applications requiring greater mechanical strength, we also offer glass-fiber or carbon-filled PTFE options.

Frequently Asked Questions about PTFE

Can PTFE be laser cut?

No—PTFE is difficult to laser-cut due to fume generation; milling and sawing are recommended.

What are alternatives to PTFE?

Alternatives include PEEK for higher mechanical strength or UHMW-PE for improved wear resistance.

Is PTFE suitable for food contact?

Yes—pure PTFE meets FDA guidelines and is suitable for food-grade applications.

How does PTFE behave at high temperatures?

PTFE remains stable up to 260 °C and only melts at 327 °C, making it excellent in heat.

Can PTFE electrically insulate?

Yes—thanks to its high dielectric strength, PTFE is an outstanding electrical insulator.

Is PTFE resistant to UV radiation?

Yes—PTFE is fully UV- and weather-resistant and does not degrade in sunlight.

Is PTFE mechanically strong?

PTFE has relatively low tensile strength; reinforced grades can improve strength.

What are the primary uses of PTFE?

Mainly in chemical, aerospace, and machine-building industries due to its exceptional chemical and thermal resistance.
