TECAPEEK ELS nano black
ELECTRICALLY CONDUCTIVE PEEK WITH CARBON NANO TUBE FILLER
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 450 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 low levels of filler content. As a result, TECAPEEK ELS nano provides consistent surface resistivity between 102 – 104 Ω/sq, while offering significantly reduced residual stresses compared to carbon fibre reinforced grades, enabling less warpage, and bending during machining. Enhanced dimensional stability is key for achieving the tight tolerances required for semiconductor manufacturing equipment components. In addition, lower internal stress enables faster speeds and feeds, results in faster part production and better yield, which reduces fabrication costs. The outstanding properties of PEEK natural such as excellent thermal resistance (up to 260 °C), low CLTE, low moisture absorption, and high strength are retained by TECAPEEK ELS nano black.
TECAPEEK ELS nano black is included in Ensinger's semiconductor grade portfolio, thus, is produced with stringent contamination controls and offering copy exact compliance. Therefore, Ensinger ensures the highest level of quality performance consistency of this unique property profile. Moreover, the low level of ionic impurity content in the filler, as well as the low filler content, enables TECAPEEK ELS nano black to provide higher ionic purity compared to standard carbon fibre reinforced materials.
Thus, TECAPEEK ELS nano black is the perfect choice for semiconductor and electronics manufacturing equipment parts, requiring high dimensional stability and cleanliness, while protecting semiconductor devices from damaging electrostatic discharges (ESD). Throughout the various manufacturing stages, TECAPEEK ELS nano can reduce the risk of charging and subsequent ESD damages, contributing to yield, quality, and output improvements.
Where the application requires higher strength and stiffness, Ensinger also offers a conductive PEEK grade with carbon fibre reinforcement under the tradename TECAPEEK ELS CF30 black. For applications requiring a slower rate of decay of static charge in a controlled manner, Ensinger offers TECAPEEK SD black with a surface resistivity between 106 – 109 Ω/sq. For applications with temperatures not exceeding 100 °C and lower mechanical property requirements, Ensinger also offers a conductive POM-C grade under the tradename TECAFORM AH ELS black.
As with all Ensinger semiconductor grade materials, we can confirm that TECAPEEK ELS nano black meets the limitations imposed by RoHS Directive 2011/65/EU Restriction of Hazardous Substances in electrical equipment, and can also provide further conformity declarations on request.
