What is PEEK?

PEEK is a high performance plastic, which is used in industry versatile, z. B. in the automotive, petroleum or chemical industries. In medicine, PEEK has been proven for several years, including as a material for dentures.

The term PEEK is an abbreviation for PolyEtherEtherKeton. PEEK is a high-temperature polymer characterized in particular by a high temperature resistance, very good mechanical strength and good chemical resistance distinguished.

Why is PEEK used for coating surfaces?

Compared to the conventional materials for coatings, such as fluoropolymers, PEEK can be exposed to higher temperatureswithout losing its mechanical and physical properties. It's about a very strong polymer; the Resistance to abrasion or wear is much higher as that of fluoropolymers.

The very good mechanical properties are also due to a excellent creep resistance and fatigue resistance approved. In addition, PEEK has one excellent hydrolysis and chemical resistance (but not resistant to sulfuric and concentrated nitric acid). Low flammability and optional electrical conductivity complete this 'HighTec' plastic and make it a perfect base for producing functional coating systems for industrial applications.

Development of non-stick coatings with PEEK

Intensive research and development work has enabled the Rhenotherm team to to combine the positive properties of PEEK polymers with the excellent non-stick properties of fluoropolymers. The result is innovative Non-stick coatings based on PEEK.

The PEEK coating includes a special layer structure with the high-performance plastic PEEK, which is applied directly to the surface of the workpiece to be coated in combination with fluoropolymers and possibly other additives.

Advantages of non-stick coatings with PEEK

Compared to conventional non-stick coatings, Rhenotherm's PEEK coating systems stand out

  • improved scratch resistance,
  • longer lifetime,
  • higher temperature resistance,
  • better water vapor tightness,
  • improved Corrosion Protection.

Application examples

Non-stick coatings based on PEEK are particularly suitable for the Food, adhesives, rubber and paint industry, They are particularly suitable for components or surface areas which are exposed to a relatively high temperature load and to which food, adhesives or molten plastics should not adhere.

  • Sealing strips or sealing plates
  • Lötwellenrahmen
  • Sliding plates or slide rails

All coating systems based on PEEK have the Color dark brown to black, are to FDA approved for food and chemically resistant (except against sulfuric and concentrated nitric acid). If necessary, all systems can additionally with a electrical conductivity (in the area <106 Ohm).
