PAEK (Polyaryletherketone)
PAEK is a family of high-temperature materials with excellent strength and chemical resistance. The materials exhibit low moisture absorption and have very good wear properties. With higher Glass Transition temperatures than standard PEEK, PAEK materials have better creep resistance and strength at elevated temperatures.
PAEK shapes can be produced by utilizing Extrusion or Injection Molding methods. They can also be filled with a variety of materials to enhance their performance.
What are the Benefits of PAEK?
- High Strength
- Increased temperature range
- Excellent Chemical Resistance
- Good performance in Steam
- Outstanding Wear Resistance
- Very good Abrasion Resistance
