PEEK-OPTIMA™ Natural LT1 (Medium Rods)

PEEK-OPTIMA™ Natural LT1 (Medium Rods Ø 20-60 mm)

High performance biocompatible thermoplastic material, PolyEtherEtherKetone (PEEK), semi crystalline. Stockshape rod diameters between 20–60 mm for machining, for use in long term human implantation. Colour natural/beige.

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.

PEEK-OPTIMA™ is known for its outstanding biocompatibility, chemical resistance, and mechanical strength. PEEK-OPTIMA™ Natural provides a reliable and versatile solution for short and long-term implants.
