TECAPEEK ELS nano black

Electrically conductive PEEK

For applications that require a plastic with the added characteristic of electrical conductivity, Ensinger has developed PEEK ELS under the trade name TECAPEEK ELS nano black, using Victrex® PEEK 450G polymer. This material takes advantage of the addition of carbon nano tubes, which allows for a high degree of conductivity to be achieved while maintaining relatively low levels of filler content. In conjunction with the other excellent properties offered by polyaryletherketones like thermal stability, and chemical resistance, TECAPEEK ELS nano black (PEEK ELS) opens up a world of possibilities and new applications for high performance plastics.
