Polyetheretherketone is a high-performance thermoplastic engineering plastic. Its English name is: Polyether Ether Ketone, referred to as PEEK. In practical applications, it will be directly called PEEK. For example, in the medical field: "PEEK implant", in the engineering field: "PEEK plastic" "PEEK engineering plastic" and so on.
Polyetheretherketone is named by its chemical structure.
Poly: indicates that it is a polymer (polymer compound).
Etheretherketone: -(-C₆H₄-O-C₆H₄-CO-)ₙ- The repeating unit contains two benzene rings, two ether bonds and one ketone bond.
PEEK material has excellent comprehensive performance and is widely used in high-end fields such as aerospace, medical, automobile, nuclear power, etc.
Thanks to its outstanding thermal, chemical, and mechanical properties, PEEK is used in a wide range of industries:
Medical field: spinal fusion cages, orthopedic implants, dental abutments
Aerospace industry: aircraft brackets, wire coatings, and thermal insulators
Automotive: transmission components, seals, and thrust washers
Oil & Gas: downhole tool components and sealing parts
Semiconductor: wafer carriers, insulation parts
1. High temperature resistance: PEEK resin material melting point temperature: 334℃, glass transition temperature: 143℃, continuous use temperature: 260℃, short-term working temperature: 330℃. If carbon fiber or glass fiber is added for modification, its high temperature resistance will be better.
2. High strength and high rigidity: PEEK resin has good toughness and rigidity, with a tensile strength of 90-100MPa and a bending strength of 140-165MPa. It has excellent fatigue resistance to alternating stress comparable to alloy materials.
3. Chemical resistance: PEEK's corrosion resistance is similar to that of nickel steel. PEEK has good chemical resistance, especially under high temperature conditions, it is more acid-resistant and alkali-resistant than PI (polyimide). The corrosion resistance can reach Class A (this grade is divided by weight change rate. Plastics, rubber and other polymer materials are usually evaluated by the weight change rate after acid and alkali immersion. The weight change rate of Class A needs to be <±1%). It has strong resistance to acids, alkalis, and organic solvents (such as gasoline, engine oil, and ketones), which is better than most engineering plastics.
4. Self-lubricating: PEEK resin has excellent sliding properties and is suitable for use in high-load and high-speed friction scenarios.
5. Excellent electrical properties: good insulation, stable dielectric constant, can be used in high-frequency electronic devices.
6. Biocompatibility: PEEK material is very close to the modulus of the bone itself, and is biologically inert and MRI compatible. It has passed FAD certification, is non-toxic and non-sensitizing, can be implanted in the human body, and is suitable for medical implants (such as spinal fusion devices and artificial joints).
7. Flame retardancy: PEEK resin is a very stable polymer. A 1.45mm thick sample can reach the highest flame retardant standard without adding any flame retardant.
8. Radiation resistance: It has strong resistance to gamma rays and X-rays, and is suitable for aerospace and nuclear industry environments.
PEEK material is known as "plastic gold" for its unique advantages of "high temperature resistance, high strength, corrosion resistance, and biocompatibility"!
