PEEK – Polyetheretherketone

Trade names: Ketron, Hostatec, Ultrapek…

Polyetheretherketone - PEEK can be used at very high temperatures (about +260 °C) and it shows an extraordinary mechanical strength, toughness, hardness, flexural strength, torsional strength. PEEK exhibits excellent chemical resistance, very good dielectric properties up to +260 °C and a very good resistance to all kinds of radiation. PEEK has self-extinguishing properties according to UL 94.

Types:

• PEEK
• PEEK-30GF
• PEEK-MOD (Reinforced with 10% of each PTFE, graphite and carbonfibre. Very good friction, wear and tear properties)

Properties:

• very high mechanical strength
• very high rigidity (also at low temperature)
• very high thermal stability
• very high creep resistance
• very high dimensional stability
• very high radiation resistance
• very high hydrolysis resistance
• relatively low notch impact-strength
• low resistance to acetone

Application: Bearing shells, piston rings, valve seats, gears, seals, aviation, cog-wheels, pump vanes, fittings, wafer carriers, semiconductor industry…
