PEEK
PEEK (polyetheretherketone) is a high-performance, semi-crystalline thermoplastic with excellent mechanical strength and chemical resistance, even at elevated temperatures. Its outstanding dimensional stability, wear resistance and radiation resistance make PEEK suitable for the most demanding applications.
PEEK combines the low weight of plastics with mechanical properties close to those of metal, without corrosion issues.
Vanéflon supplies PEEK in rods, tubes, sheets and precision-machined parts.
Key properties
- High temperature resistance: -40/+260°C (short term +300°C)
- Very high stiffness
- Very high compressive strength
- Food contact : FDA compliant – EU 10/2011
- Low coefficient of thermal expansion
- Excellent dimensional stability
- Flame retardant
- Good chemical resistance
