PEEK RODS
PEEK Rods are cylindrical, solid stock forms precision-crafted from Polyether Ether Ketone (PEEK)—a high-performance semi-crystalline thermoplastic celebrated for its exceptional mechanical strength, superior thermal stability, and robust resistance to harsh environments. PEEK rods, which offer a special blend of lightweight design, corrosion resistance, and machinability, are designed for harsh environments where metals or conventional plastics fail. They are widely utilized in industrial, automotive, medical, and aerospace applications and are made via compression molding or extrusion.
What are the key features of PEEK Rods?
1.UL94 V-0 rated flame retardancy (self-extinguishing).
2.Extreme Thermal Resistance: Short-term exposure to 300°C (572°F); continuous use up to 250°C (482°F).
3.Low Toxicity & Smoke: Meets FAA and railroad fire safety regulations.
4. High mechanical strength (tensile strength up to 170 MPa for reinforced grades): Maintains stiffness under high loads.
5.Radiation Resistance: Resistant to sterilizing by electron and gamma beams.
6.Chemical Resistance: Resists steam, acids, bases, hydrocarbons, and automotive fluids (such as diesel and brake fluid).
7.Self-Lubricating: Wear in moving parts is decreased by a low coefficient of friction (0.3–0.4).
8.Biocompatibility: For surgical implants and instruments, medical grades satisfy USP Class VI and ISO 10993.
How many types of PEEK Rods are there?
1.PEEK Rods Filled with PTFE
Used in tribological (friction and wear) applications such as seals and sliding components; blended with PTFE (Teflon) to enhance lubrication and wear resistance.
2. Unfilled PEEK Rods, or virgin PEEK
Constructed from filler-free, pure PEEK resin.
Optimal mechanical, thermal, and chemical property balancing.
Appropriate for general engineering, food, and medical applications.
3. ESD-Safe and Conductive PEEK Rods
Used in electronics, semiconductor, and aerospace applications needing electrostatic discharge (ESD) protection; contains carbon additions for electrical conductivity.
4. PEEK Rods Filled with Glass
Higher strength, stiffness, and dimensional stability than virgin PEEK; used in mechanical, load-bearing, and structural applications; 30% glass fiber reinforcement.
5.PEEK Rods Filled with Carbon
30% carbon fiber is used for reinforcement.
Higher rigidity, wear resistance, and a lower coefficient of friction make it perfect for high-load, high-friction applications including bushings, bearings, and gears.
