Teflon ® Coating
Teflon® is the key polytetrafluoroethylene (PTFE). It’s origin, like many other great inventions in history, came by chance when in 1938 Dr. Roy J. Plunkett saw how a compressed sample of tetrafluoroethylene (TFE) polymerized becoming the first fluoropolymer with the best antiadherent properties as well as fantastic chemical and thermal resistance. DuPont started commercializing this new product in 1941, and ever since it evolved according to both the market needs band the sustainability needs, providing innovation and specialization.
Properties and benefits of Teflon ®
Teflon® solutions are used all throughout the industry improving the process and performance, increasing their life and productivity. It can be combined with other materials. Amongst its properties we highlight:
Antiadherence: Most materials detach easily from Teflon ®.
Low friction coefficient: reduction of kinetic friction coefficient within a range of 0.05 and 0.20.
Thermal resistance: Can work continuously at 260 ° C (500 ° F) and intermittently up to 316 ° C (600 ° F).
Chemical resistance: low porosity with great penetration resistance.
No humidity: water and oil repellent (hydrophobic and oleophobic).
Electric properties: high dielectric properties, low dissipation factor and high superficial resistance at a great range of frequencies.
Abrasion resistance: with great durability, resistant to scratched and abrasion.
Compatible with food contact: there are versions of Teflon ® suitable for food contact.
All PTFE Teflon® coatings are manufactured without PFOA.
Applications and versions
Thanks to all Teflon® properties, it is an ideal antiadherent coating for the industrial sector. It can be found in liquid and powder and can be applied on all sorts of pieces of all sizes and geometry. Its versatility and function makes it very valuable for sectors such as:
- Industrial manufacturing
- Energy, oil & gas
- Cookware, food industry
