TECAPEEK CMF white

Ceramic filled PEEK

TECAPEEK CMF is a composite material based on Victrex® PEEK 450G polymer, that is filled with ceramic. This materials has been specifically designed with the requirements of the semiconductor industry in mind. Because of the often intricate designs necessary for parts such as test sockets, TECAPEEK CMF has been designed with ceramic fillers to be very dimensionally stable and machinable with tightest tolerances. Ceramic filled PEEK resists the formation of burrs during machining and does not absorb moisture, allowing for more accurate and precise dimensions of even the smallest geometries, without the necessity of secondary de-burring operations. The characteristic profile of this ceramic filled PEEK is unique. Besides providing outstanding hardness and rigidity, the silicate ceramic within the plastic material also provides an effective barrier against gas and fluid permeation. The ceramic platelets distributed evenly in the material extend the diffusion path for fluids and gases. The outstanding properties of PEEK natural such as excellent thermal resistance and good processing properties are retained by TECAPEEK CMF. TECAPEEK CMF with ceramic filler is offered in white or grey pigment to allow for a choice if color is part of the design criteria.
