PEEK pepper ball is a kind of high temperature-resistant thermoplastic ball with high glass transition temperature. PEEK pepper ball can run in high temperature environment for a long time without deformation and cracking, and is applied to many special fields.PEEK pepper ball main features and advantages:

1: High temperature resistance. The long-term use temperature is 260℃. Even when the temperature reaches 300℃, it can still maintain excellent mechanical properties

.2. Wear resistance In many extremely harsh application environments such as high temperature, high load and strong corrosion, PEEK polymer and its composites have good wear resistance.

3. Self-lubrication has a low friction coefficient, can realize oil-free lubrication, and can work in oil, water, steam, weak acid and alkali and other media for a long time.

4: Corrosion-resistant, insoluble in common solvents, and has good corrosion resistance to various organic and inorganic chemical reagents.

5. High strength has good mechanical strength in plastics. At the same time, it also has high rigidity and surface hardness

.6. Easy to process. Parts can be directly processed by injection molding process. It can be used for post-processing such as turning, milling, drilling, tapping, bonding and ultrasonic welding.

7: Hydrolysis resistance. PEEK products can still work continuously for thousands of hours without obvious performance degradation when soaked in steam with temperature exceeding 250℃ or in high-pressure water.

8: Flame Retardancy Without using any additives, the flammability grade of 1.45㎜ thick PEEK sample is UL94V-0.

9: The amount of smoke and toxic gas is particularly low when low-smoke and non-toxic combustion occurs.

10: The electrical performance can still maintain stable and excellent electrical performance in a wide temperature and frequency range.

11: Radiation resistance has strong resistance to high-dose gamma-ray radiation, and its mechanical properties can be completely preserved, so it can be used as radiation-resistant parts in nuclear equipment.12: Dimensional stability
