TEFLON®
Teflon®, known scientifically as polytetrafluoroethylene (PTFE), is a fluoropolymer with exceptional properties. Widely used in many industrial sectors, it is appreciated for its chemical resistance, low coefficient of friction and ability to withstand extreme temperatures.
Advantages of Teflon®
Teflon® products feature a unique combination of properties that make them particularly suitable for demanding industrial applications. Key advantages of Teflon® include :
- Excellent chemical resistance: this material offers exceptional resistance to organic chemicals, acids and bases.
- High wear resistance: These materials are designed to resist abrasion and wear, making them ideal for harsh environments.
- Optimum fatigue resistance: This fluoropolymer is renowned for its ability to maintain its mechanical properties under repeated stress.
- Ease of processing: Thanks to their ease of melt processing, Teflon® products can be easily transformed into complex components. It is also relatively simple to process, whether by machining, additive manufacturing or injection molding.
- High purity: Grades of this material are produced to the strictest standards, guaranteeing high purity and exceptional dimensional stability.
- Thermal resistance: Parts made from this material offer superior thermal resistance with a higher glass transition temperature than traditional grades.
