Medical PEEK carbon fibre reinforced

Ensinger's PEEK CF30, otherwise known as TECAPEEK CF30 black, can also be supplied in a version that is suitable for medical applications. For this PEEK CF 30 medical grade, special carbon fibres are combined with Victrex® PEEK polymer in order to fulfil the requirements for biocompatibility according to ISO 10993, which are tested on the stock shape. Additional information on USP Class VI is available. Ensinger will issue the relevant certification on an order related basis.
