Ceramic filled PEEK TECAPEEK CMF grey

TECAPEEK CMF grey is a composite material based on Victrex® PEEK 450G polymer, that is filled with ceramic and grey pigment. TECAPEEK CMF grey is a colour alternative with the same properties as TECAPEEK CMF white, thus, is suitable for applications where the white colour can cause reflections that distort optical systems, or for applications where grey colour is visually preferred.

The TECAPEEK CMF series has been designed with ceramic fillers to offer the highest level of dimensional stability and micro machinability of tight tolerances, which are key properties needed for machining fine features of IC test sockets and electronic fixtures.

The ceramic filler system allows for high accuracy and precise dimensions of microstructures by resisting burr formation and deformations during machining, as well as minimising moisture absorption. Reducing the necessity of secondary deburring operations lowers fabrication costs. The right level of stiffness and elongations allows machinability of micro holes smaller than 0,1 mm with high hole position accuracy.

Elevated level of rigidity also enables one to resist bending of parts with thin cross sections. TECAPEEK CMF grey retains the outstanding characteristics of PEEK natural such as high temperature resistance (260 °C), low thermal expansion, low moisture uptake, and excellent strength.

Compared to fibre-reinforced plastics, ceramic filled peek offers reduced drill bit deflection, enabling higher hole position accuracy. Reduced drill bit wearing compared to fibre-reinforced plastics result in longer drill bit lifetime, impacting machining costs. Compared to injection molded plates, TECAPEEK CMF is produced via an extrusion molding technology resulting in less residual stresses, warpage, and bending during machining. Low internal stress and warpage is crucial for realising the stringent flatness tolerances of contact plates with thin cross sections. Moreover, lower internal stress enables faster speeds and feeds during machining, resulting in faster part production and better yield, which reduces fabrication cost and time.

TECAPEEK CMF grey is included in Ensinger's semiconductor grade portfolio, that is produced with stringent contamination controls and offering copy exact compliance. In this way, Ensinger ensures the highest level of cleanliness and quality performance consistency of this unique property profile. With TECAPEEK SD black, Ensinger also offers a ESD version with comparable properties for enhanced micro machinability.

As with all Ensinger semiconductor grade materials, we can confirm that TECAPEEK CMF grey 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.
