PEEK MDP

HPMs – High-performance materials

PEEK MDP

PEEK MDP is a polyether ether ketone that can be detected with metal detectors. A metal additive has been added to it to make it easier to detect in pharmaceutical and food production processes. Even the smallest particles of the material can be detected with standard metal detectors. Thanks to its blue colour, it is also visible with optical detectors. All the additives used in the material are of food grade.
