I. Reliable Sealing Solutions – Mascot PEEK Sealing Rings / PEEK Sealing Rings**
Mascot PEEK sealing rings offer excellent performance, stable dimensions, and customizable specifications. They are resistant to high temperatures and wear, and possess strong mechanical properties. High-temperature PEEK has a high glass transition temperature and melting point (343°C), which is one of the reasons for its reliable application in situations with heat resistance requirements. Its heat deflection temperature under load reaches 316°C, with a continuous service temperature of 260°C. PEEK exhibits comprehensive properties among high-performance polymers that are unmatched by other general-purpose plastics, making it suitable for various harsh environments. It has been successfully and widely used in demanding applications across industries such as aerospace, automotive, electronics, semiconductors, and electromechanics. It is an ideal material for customers developing new products and aiming to improve product lifespan and reliability.
II. Main Characteristics and Advantages of PEEK**
1. **High Temperature Resistance:** Certified by UL (USA) for long-term service up to 260°C. Even at temperatures as high as 316°C, it can still maintain good mechanical properties.
2. **Wear Resistance:** In many extremely harsh application environments involving high temperatures, high loads, and strong corrosion, PEEK polymers and their composites exhibit excellent wear resistance.
3. **Self-Lubrication:** Possesses a low friction coefficient, enabling oil-free lubrication and long-term operation in media such as oil, water, steam, and weak acids and alkalis.
4. **Corrosion Resistance:** Insoluble in common solvents and demonstrates good resistance to various organic and inorganic chemical reagents.
5. **High Strength:** Offers excellent mechanical strength among plastics, along with high rigidity and surface hardness.
6. **Ease of Processing:** Parts can be manufactured directly through injection molding. Post-processing such as turning, milling, drilling, tapping, bonding, and ultrasonic welding is also feasible.
7. **Hydrolysis Resistance:** PEEK products can operate continuously for thousands of hours in steam exceeding 250°C or immersed in high-pressure water without significant performance degradation.
8. **Flame Retardancy:** Without using additives, a 1.45mm thick PEEK sample achieves a UL94 V-0 flammability rating.
9. **Low Smoke and Non-Toxic:** Emits particularly low levels of smoke and toxic gases during combustion.
10. **Electrical Properties:** Maintains stable and excellent electrical performance across a wide range of temperatures and frequencies.
11. **Radiation Resistance:** Possesses极强的 resistance to high-dose gamma radiation, retaining its mechanical properties fully, making it suitable for radiation-resistant components.
12. **Dimensional Stability**
