PEEK-CLASSIX BC2 Granules

High performance biocompatible thermoplastic material, PolyEtherEtherKetone (PEEK), semi crystalline. Granules for injection moulding and extrusion, medium flow, suitable for medical devices that will be in contact with human tissue for 30 days or less. Colour natural/beige.

Typical Application Areas
For use in applications requiring high strength, high stiffness, and high ductility. Suitable for medical devices that will be in contact with human tissue for 30 days or less. As PEEK is hygroscopic, drying before use is recommended. Further information is available upon request.

PEEK-CLASSIX™ offers a high-performance polymer solution with a low level of extractables and leachables, and chemical resistance to drug concentrates, and the extremes found within the human body.

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: >1 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.
