TECAPEEK ELS CF30 black

Electrically conductive PEEK with carbon fibre reinforcement

PEEK ELS CF 30 is a 30% conductive carbon fibre filled PEEK material, produced and marketed by Ensinger under the brand name TECAPEEK ELS CF 30 black. This electrically conductive plastic provides a very high stiffness and creep resistance through the conductive carbon fibres. Conventional carbon fibres do not have a defined conductivity, therefore, this special carbon reinforced PEEK ELS was developed as a solution for electronic applications. This material can also be used in ESD applications which require a good electrical conductivity. TECAPEEK ELS CF30 black has enhanced mechanical properties in comparison to TECAPEEK ELS nano black, which is also an electrically conductive PEEK black. Furthermore, carbon fiber modified materials are less abrasive than glass fibre modified materials, while also having enhanced wearing and friction properties.
