PEEK cable has super strong mechanical properties, good toughness and rigidity, fatigue resistance, flame retardancy, and can be used in special environments such as radiation, irradiation, salt spray, high humidity, and oil stains. TST CABLES PEEK cable is often used in aerospace, petrochemical, nuclear industry, rail transportation and other fields due to its excellent performance.
1. Halogen-free performance
PEEK material molecules do not contain halogen atoms, and the material does not produce acidic and toxic gases after combustion. It meets the EU RoSH and other environmental protection requirements and is an environmentally friendly material.
2. Volume resistance
Over a wide temperature range, ordinary PEEK polymers can still maintain a high volume resistivity value. 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 with excellent insulation properties.
3. Surface resistance
The surface resistivity of PEEK at 25°C and 50% humidity reaches 2. 0 × 1016 Ω, which is better than plastics such as fluoroplastics, polyamides, and polyimides.
4. Dielectric constant and dielectric loss factor
The dielectric constant of PEEK5600G is only 3.2, slightly higher than polyethylene (PE) and fluoroplastics, but much lower than polyvinyl chloride (PVC). In the frequency range of 109 Hz, ordinary PEEK polymers have good electrical properties. Many of the electrical properties of this material meet the typical properties of thermoplastic materials, and PEEK polymer also maintains these excellent insulation properties over a wide range of temperature and frequency. PEEK material has a small tan δ loss below 140°C. PPS is polyphenylene sulfide, PES is polyether sulfone, PC is polycarbonate, and PSU is bisphenol A type polysulfone.
5. Heat resistance
PEEK polymer has a glass transition temperature of 143°C. Since it is a semi-crystalline thermoplastic material, it can still maintain excellent mechanical properties near the melting point of 343°C. Fatigue resistance and creep resistance are higher among thermoplastics.
6. Flame retardancy
PEEK is self-extinguishing. Without adding flame retardants, the UL standard is measured to reach 94V-1 (thickness 0.3 mm), 94V-0 (thickness 1.5 mm), and 94V-5 (thickness 3.2 mm). In addition, the amount of smoke generated during combustion is also very small.
7. Environmental resistance
PEEK is only soluble in concentrated sulfuric acid and has good chemical resistance, especially at high temperatures, it is much better than polyimide in terms of acid and alkali resistance. At the same time, PEEK has a very low water absorption rate, and the saturated water absorption rate at 23°C is only 0.5%. It also has good hot water resistance and can be used in pressurized hot water or steam at 300°C.
8. Radiation resistance
It has strong resistance to γ radiation, which exceeds the radiation-resistant polystyrene among general resins. It can be made into wires that can still maintain good insulation performance when the γ irradiation dose reaches 850KGy.
