Advanced PEEK
Filament Solutions
Engineered for extreme performance. From medical implants to aerospace components, our PEEK and PEKK filaments define the future of additive manufacturing and industrial weaving.
Why Choose Our PEEK Materials?
Replacing metal with high-performance polymers reduces weight without compromising strength.
Thermal Resistance
Withstands continuous use up to 260°C and short-term exposure up to 300°C. Ideal for engine parts and sterilization.
Metal Replacement
80% lighter than stainless steel with excellent fatigue resistance and mechanical strength. Perfect for aerospace.
Biocompatible
Our implant-grade PEEK meets YYT0660-2008 standards with a modulus close to cortical bone. X-ray transparent.
3D Printing PEEK Filament
Our high-toughness, high-strength PEEK filaments are produced via continuous extrusion, ensuring dimensional stability for kilometers of printing without breakage. Designed for medical and industrial applications where failure is not an option.
Key Applications
- ● Medical Implants: Customizable structures matching patient needs, X-ray transparent, and chemically stable.
- ● Aerospace & Auto: Lightweight components resistant to hydrolysis and flame.
- ● Oil & Gas: Excellent chemical resistance for complex parts.
PEKK: Polyetherketoneketone
Higher thermal performance and rigidity than standard PEEK due to a unique E/K ratio.
Why upgrade to PEKK?
PEKK contains more rigid benzene rings and ketone groups (Ratio 2:1) compared to PEEK. This unique molecular structure results in higher melting points, better glass transition temperatures, and superior compressive strength.
Extreme Heat
Short-term exposure up to 300℃. Pure resin HDT 150-175℃.
Chemical Proof
Resistant to almost all organics/inorganics except specialized acids.
Flame Retardant
Inherently low smoke and low toxicity.
Aerospace Ready
Used in Boeing's Starliner space capsule.
PEKK Chemical Structure & Filament
Applications: Filter Cloth & Cable Insulation
PEEK Monofilament (Fiber)
Extruded from PEEK 5602G specialized raw material, our monofilaments break traditional process limitations. They offer exceptional insulation, strength, and biocompatibility for weaving and filtration industries.

PEEK Filament
Polyether ether ketone, or PEEK, is one of the highest performing polymer plastics available.
This high-purity and high-temperature polymer has excellent dielectric properties, a very
low coefficient of friction, and withstands the most rigorous physical and mechanical
stresses.
JUNHUA ChinaPEEK manufactures PEEK tubing by extrusion，precision PEEK tubing are mainly used
in HPLC and medical industry, all PEEK tubing is extruded in JUNHUA's GMP standard clean
room. JUNHUA ChinaPEEK can ensure OD & ID ±0.03mm tolerance in our standard extruded tubing.
Colored PEEK tubing, color stripped PEEK tubing and special modified PEEK tubing is also
available.
Main Advantages of PEEK Filament
- ● Good wearing performance with or without load
- ● High service temperature(long term 260C
- ● Good mechanical strength
- ● Good chemical resistance & Hydrosis resistance
- ● FDA approved
