3D Printed PEEK Filament
Medical implanted PEEK pure material: It has mechanical properties such as excellent rigidity,
toughness and durability. The modulus is close to natural leather bone. It has passed the various
test requirements of YYT0660-2008 and obtained a third-party verification report.
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-temperature
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 benzene 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.
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.
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.
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.
AKSOPEEK is the registered brand for implantable PEEK. The authority license is under
