PTFE coatings possess a range of distinguished properties that set them apart. These coatings offer exceptional non-stick properties, making them a preferred choice for various applications. With a very low friction coefficient, resistance to many chemicals and suitability for both low and high temperatures, PTFE is a versatile material.
We apply PTFE coatings to both new parts and components that have previously been coated. As there are several types of fluoropolymer coatings, there is no universal solution for every problem. That is why we always select the most suitable coating based on your application and operating conditions. Most coatings in our range are also FDA-certified for direct contact with food (FDA 21 CFR 177.1550).
Properties per coating type
PTFE Coating
- Offers excellent non-stick properties (non-stick)
- With a very low friction coefficient ranging from 0.04 to 0.08, this product is well-suited for applications requiring minimal friction.
- However, its limited chemical resistance due to its microporous nature means it may not be the optimal choice as a chemical barrier.
- It is designed to withstand temperatures ranging from -200 °C to +280 °C, making it suitable for a wide range of applications.
- The material is certified as physiologically inert and approved by the FDA, ensuring its safety for various uses.
- Please note the maximum layer thickness to ensure optimal performance.
- 30–40 µm, sintering temperature +380 to +430 °C Heat transfer coefficient 0.25 W/m·K
PFA Coating
- Good anti-adhesive properties (non-stick) Excellent chemical resistance thanks to a pore-tight structure
- This product is suitable for temperatures ranging from -200 °C to +260 °C.
- It is physiologically inert and FDA approved.
- It is often used in combination with FEP: PFA as a base layer, FEP as a top layer, for a very dense and wear-resistant coating.
- The maximum layer thickness is 50–150 µm, and the sintering temperature is +360 to +390 °C
- Heat transfer coefficient: 0.19 W/m·K
FEP Coating
- Offers excellent non-stick properties and outstanding chemical resistance.
- Suitable for extreme temperatures ranging from –200 °C to +205 °C.
- This product is physiologically inert and has FDA approval.
- Its wear-resistant and mechanically strong coating has a maximum layer thickness of 40–100 µm.
- The sintering temperature is +350 to +400 °C, and the heat transfer coefficient is 0.20 W/m·K.
