Description
PEEK Rod is a high-performance engineering plastic known for its exceptional mechanical properties and temperature resistance. Ideal for use in aerospace, medical, and chemical industries.
Material Properties
PEEK, or Polyetheretherketone, is a semi-crystalline thermoplastic that exhibits outstanding mechanical strength and temperature stability. It can withstand temperatures ranging from -50°C to +250°C, with a short-term operating temperature of up to 300°C. Its melting point is 343°C, making it suitable for high-temperature applications.
Performance and Applications
PEEK Rod is utilized in demanding environments, including seals, backup rings, valves, and components in the aerospace and medical sectors. Its excellent chemical resistance and biocompatibility make it a preferred choice in applications requiring durability and reliability.
Machining and Handling
Machining PEEK Rod requires careful handling to prevent surface cracks and internal stresses. It is recommended to use silicon carbide cutting tools and to machine dry, with pure water as the best coolant to maintain biocompatibility.
Advantages and Limitations
PEEK Rod offers high tensile strength, chemical resistance, and low flammability. However, its relatively high cost may limit its use to high-value applications. It is not suitable for close tolerance bearings at temperatures exceeding 150°C.

FAQ
Q: Is PEEK Rod suitable for food applications?
A: Yes, natural PEEK grades comply with FDA regulations for extensive food contact.
Q: Can PEEK Rod be glued or bonded?
A: PEEK Rod is difficult to bond due to its low surface energy; surface roughening may help.
Q: What are the unique characteristics of PEEK Rod?
A: PEEK has high radiation resistance and can absorb over 1000 units of radiation without losing mechanical properties.
