PEEK wire anchor is made of PEEK material and is suitable for repairing soft tissue injuries in joints such as shoulder, ankle, knee, hip, and wrist.
Excellent properties of PEEK
PEEK material is a new type of implant-grade material. Its scientific name is polyetheretherketone. After injection molding, it is suitable for repairing soft tissue injuries in joints such as shoulder joints, ankle joints, knee joints, hip joints, and wrist joints.
Features:
(1) The anchor is made of PEEK material, which is high in strength and radiolucent. The image during CT examination will be clearer, and the repair condition after treatment can be seen.
(2) Special thread design makes it easy to knock in, has higher pull-out resistance and is securely fixed.
(3) The thread surface is specially designed to facilitate bone ingrowth.
(4) Resistant to high temperatures and poor heat conduction, it is more comfortable after peek material repair.
(5) PEEK material has good biocompatibility and its modulus is similar to that of human bone.
(6) The matching suture has a good feel and is easy to tie, and its tensile strength is 15% higher than similar products.

What is PEEK？
PEEK and its modified composite materials show excellent performance under high temperature and high humidity conditions. PEEK have excellent chemical corrosion resistance, self-lubricating, and wear-resistant properties, so it has become the most ideal material to replace copper alloys and ordinary rubber. Compared with them, PEEK has longer service life which can reduce equipment operating costs, improve equipment operating reliability.
High Temperature Performance
PEEK’s performance can remain stable in the temperature range from -196°C to 260°C. Under extreme working conditions, it can withstand 300″C for a short time. The performance of PEEK is still reliable even in high temperatures of several kilometers underground work environment.
High Strength and Wear Resistance
Compared with other plastics, PEEK is resistant to compression, impact and also have good fatigue resistance. PEEK is durable in mechanical equipment and wear-resistant environments.
Double the Service Life
PEEK sealing solutions can improve the part service life. Some domestic chemical companies use the PEEK5600FE20 polytetrafluoroethylene modified material designed by JUNHUA PEEK to replace the original material, the service life of the wear parts can even be extended by 1.3-3 times.
Corrosion Resistance
PEEK is chemically inert, and has no reaction to most acids, oils, greases and all other organic and inorganic solvents or enzymes, and can still maintain good strength and dimensional stability.
Self-lubricating
PEEK has low friction coefficient, low running resistance, can be used without oil in some working conditions. The equipment is cleaner, thus improving process reliability, improving energy efficiency and saving costs.
More dom in Design
Injection molds can be used for rapid injection molding of large quantities of complex special-shaped parts, and the cost is low compared to machining.

Common PEEK Grades and Properties
1. PEEK5600G (brown-gray/khaki) is made from pure polyetheretherketone resin and offers the best toughness and impact resistance of all PEEK grades. Pure PEEK can be sterilized using convenient methods (steam, dry heat, ethanol, and gamma-rays), and the raw materials used in its manufacture comply with EU and US FDA food compatibility regulations. These characteristics make it widely used in the medical, pharmaceutical, and food processing industries.
2. PEEK5600LF30 (black) The addition of PTFE, graphite, and carbon fiber makes PEEK5600LF30 a bearing-grade plastic. Its superior tribological properties (low coefficient of friction, wear resistance, and high peak pressure limit) make it an ideal material for this class of friction applications.
3. PEEK5600GF30 (Brown-Gray): This material is a reinforced grade of plastic filled with 30% glass fiber. It offers superior rigidity, creep resistance, and dimensional stability compared to PEEK, making it ideal for structural parts. It can withstand fixed loads for extended periods at high temperatures. If PEEK5600GF30 is used as a sliding component, its suitability should be carefully verified, as the glass fiber can scratch mating surfaces.
4. PEEK5600CF30 (Black): This material is reinforced with 30% carbon fiber. It offers superior mechanical properties (higher elastic modulus, mechanical strength, and creep resistance) and wear resistance compared to PEEK5600GF30. Furthermore, carbon fiber-reinforced plastic has 3.5 times the thermal conductivity of unreinforced PEEK, dissipating heat more quickly from the bearing surface.
