PEEK-OPTIMA Wear Performance MOTIS Granules

High performance biocompatible thermoplastic material, 30% milled pitch carbon fibre reinforced PolyEtherEtherKetone (PEEK), semi crystalline. Granules for injection moulding and extrusion, standard flow, for use in long term human implantation. Colour black.

Typical Application Areas
Milled pitch carbon fiber composite, specifically designed for tribological applications particularly against a hard counterface such as metal or ceramic whilst maintaining lightweight and radiolucent properties.

Suitable for use in long-term implantable medical devices. Excellent sterilisation resistance. As PEEK is hygroscopic, drying before use is recommended. Further information is available upon request.

Injection Notes
Drying Temperature / Time: 150°C / 3h or 120°C / 5h (residual moisture <0.02%) Runner: Die / Nozzle >3 mm, Manifold >3.5 mm Gate: >2 mm or 0.5 x part thickness Important Notes: 1) Processing conditions quoted in our datasheets are typical of those used in our processing laboratories Data for mould shrinkage should be used for material comparison. Actual mould shrinkage values are highly dependent on part geometry, mould configuration, and processing conditions. Mould shrinkage differs for along flow and across flow directions. “Along flow” direction is taken as the direction the molten material is travelling when it exits the gate and enters the mould. Mould shrinkage is expressed as a percent change in dimension of a specimen in relation to mould dimensions. 2) Data are generated in accordance with prevailing national, international and internal standards, and should be used for material comparison. Actual property values are highly dependent on part geometry, mould configuration and processing conditions. Properties may also differ for along flow and across flow directions.
