The advantages and related characteristics of PEEK plate and bar are as follows

1. The material has excellent dielectric properties up to 260 ℃. It can resist the irradiation of energy rays and corrosion.

2. It is a high temperature resistant thermoplastic with high glass transition temperature (155 ℃) and melting point (334 ℃). The loading thermal deformation temperature is as high as 335 ℃ (30% glass fiber or carbon fiber reinforced brand) ）Compared with other high-temperature resistant plastics such as PTFE and PPO, peek rod not only has excellent heat resistance, but also has 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 is about 24MPa at 200 ℃, and its bending strength and compressive strength are still 12-13mpa at 250 ℃; peek resin has large rigidity, good dimensional stability, small linear expansion coefficient, which is very close to aluminum; it has excellent chemical resistance, and only concentrated sulfuric acid is used in common chemicals It can dissolve or destroy it. Its corrosion resistance is similar to that of nickel steel. At the same time, it has flame retardancy. It can release less smoke and toxic gas in flame condition, and has strong radiation resistance;

4. Peek bar has good toughness, excellent fatigue resistance to alternating stress, which is comparable with alloy materials; peek bar has outstanding tribological characteristics, excellent sliding wear resistance and fretting wear resistance, especially can maintain high wear resistance and low friction coefficient at 260 ℃ It has comprehensive properties, good mechanical properties, high temperature resistance and chemical resistance, making it the most common advanced plastics.
