PEEK bar: Chinese: PEEK bar. It is extruded from English Wiggs PEEK raw material. The material has excellent dielectric properties before the temperature reaches 260 ℃. It can resist energy radiation. It is a high temperature resistant thermoplastic, with a high glass transition temperature (143 ℃) and melting point (334 ℃), a load thermal deformation temperature of up to 316 ℃ (30% glass fiber or carbon fiber reinforced grade), and can be used for a long time at 250 ℃. Compared with other high temperature resistant plastics such as PI, PPS, PTFE, PPO, etc., the upper limit of the use temperature is nearly 50 ℃ higher; PEEK bars not only have excellent heat resistance than other high temperature resistant plastics, but also have high strength, high modulus, high fracture toughness and excellent dimensional stability; 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 sulfur

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; 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 resistance and fretting wear resistance, especially high wear resistance and low friction coefficient at 250 ℃; PEEK has excellent comprehensive properties, good mechanical properties, high temperature resistance, excellent chemical resistance, making it a senior plastic for Z general use.
