What is Polyether Ether Ketone PEEK

Invibio® PEEK-Optima ® LT1 is a polyether ether ketone PEEK material specifically developed for medical implants and nursing devices.
It combines a pure chemical structure, stable biological inertness and excellent mechanical toughness. After decades of clinical verification, it has become a reliable alternative metal material recognized in the medical industry.

01 | Core Material Properties

Biocompatibility and low extract characteristics

PEEK-OPTIMA® LT1 strictly controls the content of organic residues and ionic impurities during the polymerization and purification process to ensure low extract and low residue.
The material has been certified by ISO 10993 series biological assessment and can be in long-term contact with human tissues without causing inflammation or degradation reactions.

High purity and chemical stability

This polyether ether ketone PEEK resin can resist the erosion of body fluids, drugs and cleaning agents for a long time. Even under repeated sterilization or high-temperature conditions, its molecular structure can still remain stable and no soluble substances are precipitated.

Multiple sterilization compatibility

PEEK-OPTIMA® LT1 supports the following sterilization methods:

  ・Ethylene oxide (EO)

  ・Gamma-ray irradiation

  ・High-temperature steam (Autoclave)

  ・Plasma and Dry Heat

Its molecular stability ensures that its mechanical properties remain unchanged after hundreds of sterilization cycles, making it an ideal material for highly reusable medical components.

Excellent mechanical and physical properties

PEEK-OPTIMA® LT1 combines high strength, good ductility and low moisture absorption.
This performance balance enables it to maintain structural stability even when subjected to impact, bending or long-term loads, making it particularly suitable for load-bearing implants.

03 | Trends in Medical Applications and Alternatives

This material is widely used in:

  ・Spinal and orthopedic implants: fusion cages, intervertebral support blocks, fixation plates

  ・Dental restoration structures: bases, dental implant connectors

  ・Surgical instrument components: Structural parts, sleeves and handles that require repeated sterilization

Compared with metallic materials, polyether ether ketone PEEK has the following alternative advantages:

  ・The elastic modulus is close to that of human bones, reducing the stress shielding effect

  ・Non-conductive and non-heat-conductive, enhancing patient comfort

  ・No metal artifacts, facilitating postoperative CT/MRI imaging

04 | Flexibility in processing and design

  ・Invibio PEEK-OPTIMA® LT1 is suitable for injection molding, extrusion and calendering.

  ・Under the conditions of precision molds, complex-structured parts can be achieved, with stable thermal stability and flow performance, ensuring the accuracy and surface quality of the parts.

  ・Its low shrinkage rate and low hygroscopicity make it suitable for multi-cavity molds and long-cycle mass production.
