The Properties Of Polyetheretherketone Bars Or PEEK Rods
The material has excellent dielectric properties until the temperature reaches 260 degrees. And can resist energy ray irradiation, anti-corrosion and other important properties. It is a high temperature resistant thermoplastic with high glass transition temperature (155°C) and melting point (334°C), and the thermal deformation temperature under load is up to 335°C (30% glass fiber or carbon fiber reinforced grade), and can be used for a long time at 250°C Compared with other high-temperature-resistant plastics such as PTFE, PPO, etc.,
The upper limit of the operating temperature is nearly 50 °C higher;PEEK rods not only have better heat resistance than other high-temperature-resistant plastics, but also have high strength, high modulus, high fracture toughness and Excellent dimensional stability and radiation resistance; PEEK bar can maintain high strength at high temperature, its bending strength at 200℃ is about 24MPa, and its bending strength and compressive strength are still 12-13MPa at 250℃; PEEK resin has high rigidity, good dimensional stability, small coefficient of linear expansion, and is very close to metal aluminum materials; it has excellent chemical resistance.
Among common chemicals, only concentrated sulfuric acid can dissolve or destroy it. Its corrosion resistance is similar to that of nickel steel, and at the same time, it has flame retardancy, releases less smoke and toxic gases under flame conditions, and has strong radiation resistance; PEEK rods have good toughness and excellent fatigue resistance to alternating stress. It is the most outstanding of all plastics, comparable to alloy materials;PEEK rods have outstanding tribological properties, excellent resistance to sliding wear and fretting wear, especially at 260 ° C to maintain high wear resistance and low Coefficient of friction; PEEK has excellent comprehensive properties, good mechanical properties, high temperature resistance, and superior chemical resistance, making it the most versatile high-grade plastic.
