PEEK open seal ring

1. Overview of PEEK sealing ring/PEEK sealing ring

PEEK sealing ring has good performance, stable size, customizable specifications, high temperature resistance, wear resistance, and strong mechanical properties. High temperature resistant PEEK has a high glass transition temperature and melting point (334℃), which is one of the reasons why it can be reliably used in applications with heat resistance requirements. Its load thermal deformation temperature is as high as 316℃, and the continuous use temperature is 260℃. PEEK has comprehensive properties that other general plastics cannot match in high-performance polymers. It has the performance to be suitable for various harsh environments. It has been successfully and widely used in various industries such as aerospace, automobiles, electronic semiconductors, and electromechanical, which are more demanding occasions. It is a material for users to develop new products and improve product service life and reliability.

2. Main characteristics and advantages of PEEK

1: High temperature resistant The long-term use temperature of the US UL certification is 260℃. Even when the temperature reaches 316℃, it can still maintain good mechanical properties.

2: Wear resistance In many extremely harsh application environments such as high temperature, high load, and strong corrosion, PEEK polymers and their composite materials have good wear resistance.

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

4: Corrosion resistance is 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. It also has high rigidity and surface hardness.

6: Easy to process. Parts can be directly processed by injection molding. Post-processing such as turning, milling, drilling, tapping, bonding and ultrasonic welding can be performed.

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

8: Flame retardancy Without the use of additives, the flammability rating of the 1.45mm thick PEEK sample is UL94V-0.

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

10: Electrical properties can still maintain stable and excellent electrical properties over a wide temperature and frequency range.

11: Radiation resistance It has extremely strong resistance to high-dose gamma-ray radiation, and the mechanical properties can be fully retained, and can be used as radiation-resistant parts.

12: Dimensional stability
