PEEK Cage
The PEEK Cage is made of PEEK material and can be implanted in the cervical or
lumbosacral vertebral space or used for thoracic and lumbar vertebral body replacement
and restoration of lost height due to damaged vertebral body lesions.
Why PEEK polymer is ideal material for medical device?
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
freedom and a greater functional integration, it also scores with X-ray transparency and elasticity
which corresponds approximately to bone.
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℃ (289℉), and melts around 343℃ (662℉). The carbon fiber
filled PEEK or glass fiber PEEK material have a useful operating temperature of up to 250℃ (482℉).
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 is widely used in high-end medical device.
PEEK Benefits
Small specific weight
Gravity replaces titanium alloy (4.5 g/cm³) and aluminum alloy (4.5 g/cm³) to achieve light weight.
High welding strength
The melting point is 343°C, the long-term application at 260°C, the thermal deformation temperature of
the composite material about 330°C and a higher temperature resistance.
High strength
The mechanical properties of PEEK modified by chopped fibers are slightly lower than those of aluminum alloys.
Corrosion resistance
It has corrosion resistance to most organic solvents such as acids and alkalis. It is corroded by halogens
and strong acids at high temperatures and soluble in concentrated sulfuric acid at room temperature.
Thermoplastic material
Fatigue resistance and impact resistance are significantly better than thermoset materials, have a longer
service life, are environmentally friendly and recyclable.
Material stability
It better reflects the characteristics of low gas release in space and vacuum coating environment.
Wear resistance
High hardness and low coefficient of friction.
Stable dimension
PEEK reduces the expansion coefficient and thus radically reduces the risk of swelling.

Knockout Product
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 a 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 in China, 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 in China 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.
JUNDE Medical is always at the forefront of the market. Since the middle of 2020 year, JUNDE 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 JUNDE company provide the
OEM service.
Implantable PEEK
AKSOPEEK is the registrated brand for implantable PEEK. The authority license is under the process
and it will be gained in the end of 2022 as plan. AKSO is the representative of the goddess of health
in ancient Greek mythology. AKSO is the medical grade long-termed implantable PEEK by JUNDE medical.
Four kinds of implantable PEEK will be available:
AKSOPEEK Natural、AKSOPEEK HA、AKSOPEEK CF、AKSOPEEK LCF
