It can adapt to all the sterilization methods commonly used in medicine. Because of its columnar stiffness and thin wall, the bending radius is very small, which helps to manipulate the tortuous path of the catheter through the body. The material can be sterilized using gamma, ethylene oxide (EO or EtO), electron beam or autoclave.

These include: cardiac puncture surgery, varicose vein radiofrequency ablation, cardiac radiofrequency ablation, minimally invasive abdominal devices, etc.

3. Catheter drilling: round hole, elliptical hole, through hole, single-sided hole, square hole, special-shaped hole (aperture range 0.1-10mm)

PEEK Introduction and Characteristics
Polyetheretherketone resin (PEEK resin for short) is a new type of semi-crystalline aromatic thermoplastic engineering plastic made by condensation reaction of 4,4′-difluorobenzophenone and hydroquinone in the presence of alkali metal carbonate and diphenyl sulfone as solvent. It is a high temperature resistant thermoplastic plastic with a high glass transition temperature (143℃) and melting point (343℃), and a load heat deformation temperature of up to 316℃ (30% glass fiber or carbon fiber reinforced grade). It can be used for a long time at 250℃. Compared with other high temperature resistant plastics such as PI, PPS, PTFE, PPO, etc., the upper limit of the use temperature is nearly 50℃ higher;

1. High temperature resistance PEEK has a high glass transition temperature and melting point (343°C), which is one of the reasons why it can be reliably used in applications requiring heat resistance. Its load heat deformation temperature is as high as 316°C, and the continuous use temperature is 260°C.
2. Wear resistance PEEK materials have good wear resistance in harsh environments such as high temperature, high load, and strong corrosion.
3. High strength PEEK has good mechanical strength, toughness and rigidity and is a balanced plastic. In particular, its excellent fatigue resistance to alternating stress is outstanding among all plastics and comparable to alloy materials.
4. Self-lubricating property PEEK has outstanding sliding properties among all plastics and is suitable for use in applications that strictly require low friction coefficient and wear resistance. In particular, PEEK modified by mixing carbon fiber and graphite in a certain proportion has better self-lubricating properties.
5. Chemical resistance (corrosion resistance) PEEK has excellent chemical resistance. Among common chemicals, only concentrated sulfuric acid can dissolve or destroy it. Its corrosion resistance is similar to that of nickel steel.
6. Flame retardancy : PEEK is a very stable polymer. A 1.45 mm thick sample can reach a high flame retardant standard without adding any flame retardant.
7. Peel resistance : PEEK has good peel resistance, so it can be made into thinly coated wires or electromagnetic wires and can be used under harsh conditions.
8. Fatigue resistance : PEEK has the best fatigue resistance among all resins.
9. Electrical properties PEEK can maintain stable and excellent electrical properties over a wide range of temperature and frequency.
10. Radiation resistance : It has a strong ability to resist gamma radiation, which exceeds that of polystyrene, which has good radiation resistance among general resins. It can be made into high-performance wires that can still maintain good insulation ability when the gamma radiation dose reaches 1100 Mrad.
11. Hydrolysis resistance PEEK and its composite materials are not chemically affected by water and high-pressure steam. Products made of this material can still maintain excellent properties after continuous use in high-temperature and high-pressure water.
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.
