PEEK Tubing|Medical Grade
PEEK is a high–performance material with one of the highest strength–to–weight ratios of any engineered
polymer. This material is a very rigid plastic with excellent lubricity and boasts a continuous working temperature
of 500 °F / 260°C. PEEK tubing exhibits high column strength, as well as high tensile strength and high flexural modulus, making it perfect for catheters and minimally invasive devices.
Why is PEEK a good fit for medical applications?
PEEK is polyether ether ketone, a thermoplastic, a high-performance polymer, and a critical biomaterial for many medical applications.PEEK medical catheter is different from the traditional medical catheter, the biggest characteristic is not only good toughness but also fixed rigidity.PEEK tubing has excellent fatigue resistance and good insulation among all materials at present. The insulation strength can reach 5KV with 0.2mm on one side.
Meanwhile,high-temperature resistant PEEK, medical catheter can keep excellent mechanical properties under 160°C for a long time, good dimensional stability, high strength, wear resistance, excellent chemical resistance, good impact resistance, and flame retardant, in a humid environment or high-temperature cooking will not affect its insulation strength. It can adapt to all the disinfection methods in medical treatment at present.
PEEK offers enhanced properties that make it an attractive tubing application material for medical device designers and engineers. Its high strength, resistance to the most extreme chemicals, and high-temperature dimensional stability work well in devices designed for cutting-edge neurovascular and orthopedic procedures as well as for mechanical components of medical and access devices.
PEEK Polymer advantages:
●Engineering-grade thermoplastic polymer
●Highly resistant to thermal degradation at high temperatures
●High column strength & tensile strength
●High flexural modulus & torsional stability
●Good torque transference for catheter applications
●Very high rigidity
●Excellent abrasion resistance
●Highly resistant to most chemicals
●Low moisture absorption
●Good for high vacuum or pressure applications
PEEK medical tubing is widely used in interventional and minimally invasive surgical instruments. Such as intravenous radiofrequency ablation catheters, cardiac radiofrequency ablation catheters, abdominal surgical instruments, endoscopes, etc.
PEEK Capillary Tubing|Made in China
China's medical catheter industry has begun to take shape and the overall pattern of export-oriented. This catheter is widely used for the domestic market, and also mainly exported to other countries. Meanwhile, China also imports a large number of medical catheters every year to meet the demand for different products.PEEK medical catheter belongs to a basic medical device product, which is widely used in diagnosis, treatment, monitoring, first aid, drainage, perfusion, gas transport, blood transport, and rehabilitation.
With the development of modern science and technology, as well as the increasing average life expectancy of the world population and the aggravation of the aging trend, the application scope of the medical catheter in modern medical diagnosis and treatment and home care will continue to expand, and the importance will continue to rise, and the industry has great potential for future development.
There are strict environmental requirements on the production process of PEEK medical catheters. All of the production equipment and raw materials must conform to ISO13485 standard, strict sterilization, and disinfection. Plus, PEEK catheters should be completed after the multichannel working procedure manufacture, such as ring seals, sealing side, bilge, punching, forming, etc. Junhua PEEK is the premier manufacturer in this medical tubing field.
PEEK Medical Tubing|Made by Junhua PEEK
Junhua PEEK sets up a medical-grade clean workshop to ensure the cleanliness of PEEK extrusion equipment and maximize the dust-free environment of the workshop, and control the internal cleanliness of products from a details degree, to meet the harsh standards of the medical industry.
The columnar stiffness and small bending radius of the thin wall of the medical catheter help to manipulate the catheter's tortuous path through the body. The material can be sterilized using γ-ray, ethylene oxide (EO or EtO), electron beam, or autoclave.
PEEK(Poly Ether Ether Ketone) has the advantages of high-temperature resistance, corrosion resistance, high strength, X-ray transmission, resistance to repeated disinfection, and good biocompatibility. It has been widely used in the medical industry and has been equipped with many well-known medical treatments domestic and foreign. The unit is developed and produced and successfully applied to the clinic.
