Advantages and relevant characteristics of PEEK plate and bar: PC price
1. The material has excellent dielectric properties until the temperature reaches 260 ℃. It can also resist energy radiation, corrosion and other important properties.
2. It is a high temperature resistant thermoplastic with a high glass transition temperature (155 ℃) and melting point (334 ℃). The load thermal deformation temperature is up to 335 ℃ (30% glass fiber or carbon fiber reinforced grade). It can be used for a long time at 250 ℃. Compared with other high temperature resistant plastics such as PTFE, PPO, etc., the upper limit of the use temperature is nearly 50 ℃ higher; PEEK rods not only have excellent heat resistance than other high temperature resistant plastics, but also have high strength, high modulus, high fracture toughness, excellent dimensional stability and radiation resistance;
3. PEEK bar can maintain high strength at high temperature, its bending strength at 200 ℃ is about 24MPa, and its bending strength and compression strength at 250 ℃ are still 12~13MPa; PEEK resin has higher rigidity, better dimensional stability, and smaller linear expansion coefficient, which is very close to the metal aluminum material; It has excellent chemical resistance. Among ordinary chemicals, only concentrated sulfuric acid can dissolve or destroy it. Its corrosion resistance is similar to that of nickel steel. At the same time, it has flame retardancy. It emits less smoke and toxic gas under flame conditions, and has strong radiation resistance;
4. PEEK bar has good toughness and excellent fatigue resistance to alternating stress, which is outstanding among all plastics and comparable to alloy materials; PEEK bar has outstanding tribological properties, excellent sliding wear and fretting wear resistance, especially high wear resistance and low friction coefficient at 260 ℃; PEEK has good comprehensive properties, good mechanical properties, high temperature resistance, and excellent chemical resistance, making it a universal high-grade plastic of zui.
