click to resize photo The 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 ® TS is a composite engineering thermoplastic based upon a mixture of PolyEtherEtherKetone (PEEK) or PolyArylEtherKetone (PAEK) polymer blended with a technical ceramic.

TecaPEEK TS 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 TS offers the second generation property profile for test socket applications: improved hardness combined with good toughness to create the necessary creep strength in the application and support a long life time. These properties are reflected by an excellent machinability with low burrs even with the finest structures. A high dimensional stability is given over a wide temperature range. Due to the extrusion technology, homogeneity is given in the whole stock shape so that finest parts can be taken at any position throughout the plate. Because of the unique blue-grey color, reflections in imaging systems are reduced and excellent contrast can be achieved with laser marking equipment for part identification.

•  Outstanding thermal stability
•  Very good hardness and rigidity
•  Good machinability, very low burring
•  Good dimensional stability
•  Low water absorption
•  Good corrosion resistance
•  High thermal resistance
•  Good dielectric properties

TecaPEEK TS is available in pre-molded plate / sheet shape only and is  BLUE-GREY  in color.
