Thanks to its outstanding mechanical properties, chemical resistance and, above all, exceptional heat resistance, PEEK has become indispensable. Its full name is polyether ether ketone or polyether ether ketone, a member of the PAEK family of materials. It was introduced to the market in the 1980s and 1990s by the British company Victrex.

It is characterised by excellent wear resistance, slip properties, dimensional stability and machinability, which put it above the general engineering plastics, even if we do not mention the fact that it can be used up to about 300 degrees Celsius. In the combination of all these properties, it has no rival.

Available in a wide range of finishes - you can find the right material from the PEEK range for the most specific applications. We offer glass fibre (GF or GF30), carbon fibre (CF, CF30 or CA), carbon fibre, graphite and Teflon reinforced (MOD or PVX), anti-static (ESD) and electrically conductive (ELS), detectable PEEK for food applications, and also medical and pharmaceutical PEEK in a range of colours.

They are also available in sheet, rod and tube formats in a wide range of sizes, for example, natural PEEK sheets from 1.25 mm to 130 mm thick, and rods from 4 mm to 200 mm diameter.

Some important features

• High mechanical strength (75 - 130 MPa) and hardness
• High upper application temperature limit (250-310 °C)
• High load capacity even at high temperatures
• Excellent wear resistance in a wide range of operating conditions, especially for composites
• High dimensional stability and rigidity at high temperatures
• Durable flame resistance and low smoke formation in case of fire
• The base material is a good electrical insulator and has a favourable dielectric behaviour (if it does not contain carbon fibre, graphite)
• Good resistance to strong radioactive radiation
• Ageing resistance
