I. Introduction to PEEK (Polyether Ether Ketone) Cables

PEEK insulated wires, with their outstanding resistance to high and low temperatures, flame retardancy, radiation resistance, and excellent mechanical properties, can be used as ultra-high temperature wires in the aviation industry; in the petroleum industry, they can serve as winding wires and connecting wires for submersible pump motors; in nuclear power plants, they can be used as winding coils for nuclear island drive mechanisms under long-term irradiation conditions. The excellent properties of PEEK insulated wires, such as seawater resistance, light weight, small volume, and flame retardancy, make them suitable for use in ships and high-speed traction locomotives.

  1. Halogen-free PerformancePEEK material molecules do not contain halogen atoms. When burned, the material does not produce acidic gases or toxic gases, meeting environmental requirements such as the EU RoSH, and is an environmentally friendly material.
  2. Volume ResistanceWithin a wide temperature range, ordinary PEEK polymers can still maintain a high volume resistivity. At 23°C, the volume resistivity of PEEK is above 6 × 10¹³ Ωm; at 140°C, its volume resistivity is above 8 × 10¹² Ωm; and at 200°C, its volume resistivity is above 6 × 10⁹ Ωm, still maintaining excellent insulating properties.
  3. Surface ResistanceThe surface resistivity of PEEK reaches 2.0 × 10¹⁶ Ω at 25°C and 50% humidity, which is better than that of fluoroplastics, polyamides, polyimides, and other plastics.
  4. Dielectric Constant and Dielectric Loss FactorThe dielectric constant of PEEK5600G is only 3.2, slightly higher than that of polyethylene (PE) and fluoroplastics, but much lower than that of polyvinyl chloride (PVC). Within the frequency range of 10⁹ Hz, ordinary PEEK polymers have good electrical properties. Many electrical properties of this material conform to the typical properties of thermoplastic materials, and at the same time, PEEK polymers maintain these excellent insulating properties over an extremely wide range of temperatures and frequencies. The tan δ loss of PEEK material is small below 140°C. PPS is polyphenylene sulfide, PES is polyethersulfone, PC is polycarbonate, and PSU is bisphenol A polysulfone.
  5. Heat ResistancePEEK polymer has a glass transition temperature of 143°C. As a semi-crystalline thermoplastic material, it can still maintain excellent mechanical properties near its melting point of 343°C. Its fatigue resistance and creep resistance are relatively high among thermoplastic plastics.
  6. Flame RetardancyPEEK is self-extinguishing. Without adding flame retardants, it reaches 94V-1 (thickness 0.3 mm), 94V-0 (thickness 1.5 mm), and 94V-5 (thickness 3.2 mm) when tested according to UL standards. In addition, the amount of smoke generated during combustion is very small.
  7. Environmental ResistancePEEK is only soluble in concentrated sulfuric acid and has good chemical resistance, especially in terms of acid and alkali resistance at high temperatures, which is much better than that of polyimide. At the same time, the water absorption rate of PEEK is very low, with a saturated water absorption rate of only 0.5% at 23°C. Moreover, it has good hot water resistance and can be used in pressurized hot water or steam at 300°C.
  8. Radiation ResistanceIt has strong resistance to γ radiation, exceeding polystyrene, which has good radiation resistance among general-purpose resins. It can be made into wires that still maintain good insulating properties when the γ radiation dose reaches 850 kGy.
