PEEK-OPTIMA™ Reinforced LT1CA30PL22 (Plate)

High performance biocompatible thermoplastic material, 30% carbon fibre reinforced PolyEtherEtherKetone (PEEK), semi crystalline. Plate for machining, for use in long term human implantation. Colour black.

Typical Application Areas
For use in applications requiring high strength, high stiffness, and high ductility. 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.

This grade combines the biocompatibility of PEEK with the high strength and stiffness of carbon fiber. It is specifically designed for applications requiring higher strength or stiffness.

Additional Information
Important Notes 1) Processing conditions quoted in our datasheets are typical of those used in our processing laboratories. 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 and processing conditions. Properties may also differ for along flow and across flow directions. 3) Invibio strongly recommend following the PEEK-OPTIMA™ Machining Guidelines prior to machining to reduce stresses and perform optimal machining techniques. 4) The fibre orientation within a machined part can greatly affect its tensile properties. Tensile properties are maximised when fibres are aligned with the test direction (transverse) and significantly reduced when oriented perpendicular (longitudinal). The reason for this is that the extruded melt splits upon entering the plate cavity, causing the fibres to orientate perpendicular to the extrusion direction. Storage Requirements Store in original packaging away from direct sunlight and extremes of temperatures. Do not use if sealing tab is broken prior to opening. Development Material During qualification activities NFHI (Not For Human Implantation) grades are available upon request. Detailed data available on our website www.invibio.com or upon request.
