GENERAL DESCRIPTIONThe continuing reduction of component sizes in semiconductor production has placed increasing demands on materials which will satisfy these high standards. Thin-walled and miniaturised components require materials with a pronounced degree of dimensional stability and excellent machinability.
TECAPEEK ® CMF is a composite engineering thermoplastic based upon a mixture of PolyEtherEtherKetone (PEEK) or PolyArylEtherKetone (PAEK) polymer blended with a technical ceramic.
TecaPEEK CMF fully complies with the exacting standards demanded by the semiconductor industry. The proven and tested thermal stability and machinability of unfilled TecaPEEK have been retained, but the addition of the ceramic filler offers exceptionally low water absorption, outstanding hardness and rigidity combined with excellent dimensional stability. The even distribution of the incorporated silicate ceramic discs also offers a high barrier to permeation by gases and liquids.
TECAPEEK CMF is available in pre-molded sheet shape only and is WHITE in color or GREY upon request.
