01 Domestication of raw materials

Current situation: PEEK raw materials were originally imported from Enbon, Evonik, and Victrex. Now Jida, Zhongyan, and Junhao have started mass production and sales.

02 Physical and chemical properties of PEEK materials

(1) A lower elastic modulus close to that of bone (PEEK about 3.8 GPa, cancellous bone 3.2-7.8 GPa, cortical bone 17-20 GPa, titanium alloy TC4 about 110 GPa) can prevent stress shielding effect and maintain the original strength of the surrounding bone.(3) Excellent corrosion resistance and hydrolysis resistance. Even if exposed to hot steam, ethylene oxide and gamma rays for a long time, it can still maintain its original properties. It can be used for a long time at a harsh temperature of 250°C, and the instantaneous use temperature can reach 300°C.

(5) Mechanical properties can be adjusted by adding different additives, including carbon fiber, barium sulfate and glass fiber, to meet different specific application requirements.Current applications in orthopedic medical devices:Currently, companies involved in this field, such as MDT, Depuy, Jiangsu Junhua, Smith & Nephew and other manufacturers, are all engaged in research and development and production.

02 Production of PEEK catheters

The production of PEEK medical catheters has high requirements on the environment. The equipment and raw materials must comply with ISO13485 standards and be strictly sterilized. At the same time, the catheters must undergo a lot of post-processing such as ring printing, end sealing, expansion, punching, and fixed bending. Currently, domestic manufacturers of PEEK catheters include Junhua PEEK and Fujian Anping.ConclusionPEEK is an indispensable key material for the development of high-end science and technology. What fields to apply it in and how to better apply it will be what needs to be explored for future development.
