PEEK Polymer | Medical Grade
PEEK(poly ether ether ketone) is confirmed biocompatibility material three decades ago.By the
late 1990s, medical grade PEEK polymer had emerged as the leading high-performance
thermoplastic candidate for replacing metal implant components, especially in orthopedics
and trauma devices.Unfilled PEEK biomaterials can exhibit an elastic modulus ranging between
3 and 4 GPa, the modulus can be tailored to closely match cortical bone (18 GPa) or titanium
alloy (110 GPa) by preparing carbon fiber-reinforced (CFR) composites with varying fiber
length and orientation.Medical PEEK is increasingly used as biomaterials for the medical
products.
Plus, for medical device parts,PEEK provides a great benefit: It saves weight,allows more
design dom and a greater functional integration, it also scores with X-ray transparency
and elasticity which corresponds approximately to bone.
Knockout Product of JUNHUA PEEK
PEEK and PPSU is used in many different areas of the medical industry, from implantable devices that have to be both strong and biocompatible to reusable medical instruments that have to be sterilized repeatedly using harsh processes such as autoclaving. PEEK and PPSU is an good choice for medical applications for numerous reasons, including its excellent fatigue/wear properties, high strength-to-weight ratio, and biocompatibility.
PEEK Medical Tubing
Polyether Ether-Ketone (PEEK) is an engineering grade thermoplastic polymer with
characteristics that are uniquely suited to many medical tubing applications. PEEK is a high
purity, semi-crystalline, organic polymer with excellent resistance to thermal degradation
at high temperatures. PEEK tubing exhibits high column strength, as well as high tensile
strength and high flexural modulus, making it perfect for catheters and other tubing
applications requiring good torque response and pushability.
Extruded PEEK tubing is used in medical applications where exceptionally high rigidity is
needed. Due to PEEK's excellent biocompatibility, it is a suitable choice for long-term
implants. With a modulus similar to bone, PEEK is commonly used in orthopedic implant
applications. PEEK tubing can also be found in medical applications requiring high vacuum or
pressure holding capability. The material can serve as an effective alternative to steel,
aluminum, glass, and other polymers, including use as a composite structure in reinforced
catheter shafts.
Medical PEEK for Trauma Device
30% Carbon Filled PEEK has been reinforced with carbon fibers that improve PEEK's compressive strength and stiffness, while also reducing its expansion rate. This grade of PEEK offers the best wear resistance and load bearing capabilities, while also offering 3.5 times higher thermal conductivity than Unfilled PEEK. This improves bearing life and capability. 30% Carbon Filled PEEK ( PEEK5600CF30) is available in sheet and rod in a black color. PEEK5600CF30 is also can be made the injection Trauma PEEK Targeting Device.
Medical PEEK for Sport Medicine
As the fifth category of orthopedics , sports medicine has been widely used in
orthopedics with its two core characteristics of minimally invasive surgery and reduction of
soft tissue damage.The market share of the global orthopaedic industry is as high as over
1%, with a rapid growth rate of 30% every year, which is the fastest growing segment of the
orthopaedic industry in the future.At present, more than 90% of the market share of sports
medicine is occupied by foreign medical giants. At present, medical transport is
still in the early stage of development.However, with the development of domestic orthopedic
industry, the replacement of import is an inevitable trend.In the next 3-5 years, domestic
sports medicine will focus on the development of registration, involving mold opening and
injection molding foundry, and the demand for implant-grade particles will also increase
rapidly. There are huge demands and opportunities.
Junhua Medical is always at the forefront of the market. Since the middle of 2020 year,
Junhua PEEK has started to work with dozens of trauma device manufactures to develop the
implantable intramedullary nail. The implantable PEEK material is provided by the medical
partner, and Junhua company provide the OEM service.

What is PEEK?
PEEK(Poly ether ether ketone) is the most well known and important member of the PAEK(Poly
aryl ether ketone) group. This high-performance polymer material combines high-termperature
resistance,good wear, and excellent mechanical properties. For instance, the glass
transition temperature of PEEK is around 143 °C (289 °F) ,and melts around 343 °C (662 °F).
The carbon fiber filled PEEK or glass fiber PEEK material have a useful operating
temperature of up to 250 °C (482 °F).
PEEK material is the best comprehensive performance of special engineering plastics. PEEK
shows excellent overall performance due to its large amount of benezene ring structure in
its molecule. At present, medical grade PEEK material made by Junhua PEEK is widely used in
high-end medical device.

Kinds of Medical Grade PEEK Material
What Kinds of Medical Grade PEEK Material You Have?
I. Unfilled PEEK
PEEK5600G is one of unfilled or natural PEEK.It is a high performance, high temperature, semi crystalline thermoplastic material manufactured by JUNHUA PEEK. Outstanding chemical resistance and a high operating temperature (up to 250℃/480F) round out PEEK profile.PEEK plastic has excellent dimensional stability combined with high creep stability, ensuring the suitability of PEEK for the most sophisticated machined parts. Besides, the unfilled black PEEK or black PEEK is also available.
II. 30% Carbon fiber filled PEEK
PEEK5600CF30 is a 30% carbon filled PEEK material that is manufactured by JUNHUA PEEK. Its carbon fiber reinforcement supports the material a high level of rigidity. Carbon fiber reinforced PEEK demonstrates very high mechanical strength values.However,30% carbon fiber reinforced PEEK(PEEK5600CF30,1.4±0.02g/cm3)presents lower density than 30% glass fiber filled peek(PEEK5600GF30,1.5±0.02g/cm3).Besides,carbon fiber composites tend to be less abrasive than glass fibers while simultaneously resulting in improved wear and friction properties. The addition of carbon fibers also ensures a significantly higher level of heat conductivity which is also beneficial for increasing part life in sliding applications. Carbon filled PEEK has also an excellent resistance to hydrolysis in boiling water and super heated steam.
III. CF/PEEK
CF/PEEK is obtained by thick gauge thermoforming of thin layers of previously impregnated fibres to form fully consolidated sheets, whose main difference to custom-made composite plates lies in the standardized orientation of the reinforcing fibres, standardized weight content of the polymer and standardized sheet thicknesses, thus allowing easy design and post-processing using identical or similar tools as commonly used when working with metallic light-weight materials like aluminium, titanium and steel.
IV. Customized PEEK
The customized size or shape or color of PEEK products is made by Junhua PEEK as your product designing requirement.
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.
