Teflon coating is one of the most common forms of coating with a wide variety of industrial applications. With incredible heat resistance, dielectric stability and low coefficient of friction, the material is more than just about non-stick surfaces.
Teflon coating can be applied on many materials, such as aluminum, steel, magnesium, glass, rubber, plastic and so on.
Let’s take a look at 6 common types of Teflon coating:
Teflon PTFE
Polytetrafluoroethylene or PTFE is the most widely used Teflon coating. Containing a primer and a top coat, the material has incredible engineering and industrial applications.
With a temperature resistance reaching as high as 500 degrees Fahrenheit, PTFE can handle the highest temperature rate among all the different fluoropolymers. Additionally, the material has low co-efficient of friction and high abrasion resistance. One drawback of the material is that it’s in fluid form.
Teflon FEP
Fluorinated Ethylene Propylene Copolymer or FEP is a completely non-porous film. Being perfectly non-stick, FEP coating makes the process of baking easier by melting and flowing.
The material offers great resistance against quite a few chemicals and is available in both liquid and powder form.
Teflon PFA
Similar to FEP, PFA or Perfluoroalkoxy offers non-stick coating. The material also melts and flows during baking. However, PFA has the capacity to deal with higher temperatures. Moreover, the material is stronger than both PTFE and FEP. It also comes in both liquid and powder form.
Tetzel ETFE
One of the strongest fluoropolymer, ETFE is a copolymer of ethylene and tetrafluoroethylene. It is sold by Teflon under the name Tetzel. Although the material is not fluorinated, it has remarkable chemical resistance and can operate at increasingly high temperatures. Its film can provide a superb durable finish. It comes in powder form alone.
Teflon One Coat
Composed of different blends of fluoroplastics and high quality resins, One Coat is a type of solvent-based coating that enhances the toughness and abrasion resistance. The coating works fine when applied to clean metals. Its components stratify during the process of baking and hence the material can retain its fluoroplastic properties like low friction.
Teflon Dry Lubricant
Dry lubricant is perfect for conditions that involve high pressures and velocities. Just like One Coat, this type of coating is also solvent-based. However, they are designed a bit differently to account for high pressures and velocities.
