Biomedical materials are a high-tech industry with the most interdisciplinary and knowledge-intensive industries, including metals, polymer materials, composite materials, etc. Among them, medical polymer materials are the earliest developed, most widely used, and most used materials in biomedical materials. A rapidly developing field. With the development of the implant market, PEEK (polyether ether ketone) as a new type of medical implant material is used in plastic surgery, cardiovascular, artificial spine and other fields.
PEEK has a modulus very close to that of the bone itself, and has excellent toughness and fatigue resistance. In the application of intervertebral equipment, PEEK has more advantages than titanium and cobalt-chromium alloy metal materials. It has many advantages such as biocompatibility, chemical stability, and elastic modulus similar to bone itself. With the development of the implant market, PEEK is used in more other fields: such as plastic surgery, cardiovascular, pharmaceutical and so on.
Because PEEK has electrical insulation properties and excellent mechanical properties, the cardiovascular field is using PEEK as assembly components and independent implants. In the pharmaceutical field, PEEK is the preferred material with chemical resistance to body fluids compared to other plastics. When used in injection molding, the material is light in weight, highly integrated in parts, and has greater design freedom
