PEEK sealing ring has good performance, and stable dimensions, and can be customized in size, high-temperature resistance, wear resistance, and strong mechanical properties.
PEEK has comprehensive properties unmatched by other general-purpose plastics among high-performance polymers and is suitable for various harsh environments. It has been successfully widely used in demanding situations in various industries such as aerospace, automobiles, electronic semiconductors, and electromechanical.
1. High-temperature resistance, US UL certification, long-term use temperature is 260 degree . Even when the temperature reaches as high as 316 degree , it can still maintain good mechanical properties.
2. Wear resistance: In many extremely harsh application environments such as high temperature, high load, strong corrosion, etc., PEEK polymer and its composite materials have good wear resistance.
3. Self-lubricating has a low friction coefficient, can achieve oil-free lubrication work, and can work for a long time in oil, water, steam, weak acid and alkali, and other media.
4. High strength has good mechanical strength among plastics. It also has high rigidity and surface hardness.
5. Easy processing: parts can be directly processed using injection molding technology. It can perform post-processing such as turning, milling, drilling, tapping, bonding, and ultrasonic welding.
6. Flame retardancy Without the use of additives, the flammability level of the 1.45mm thick PEEK sample is UL94V-0.
7. Electrical performance can still maintain stable and excellent electrical properties within a wide temperature and frequency range.
8. Radiation resistance: It has extremely strong resistance to high-dose gamma-ray radiation, and its mechanical properties can be completely retained. It can be used as radiation-resistant parts in nuclear equipment.
