PEEK valve seat gasket

HONYPLAS®PEEK has the heat resistance and chemical stability of thermosetting plastics and the molding processability of thermoplastics. The long-term use temperature of PEEK is about 260-280°C, the short-term use temperature can reach 330°C, and the high pressure resistance can reach 30MPa. It is a good material for high-temperature sealing rings. PEEK products are suitable for use in a variety of harsh working conditions. PEEK also has excellent properties such as good self-lubricity, easy processing, stable insulation, and hydrolysis resistance, making it widely used in aerospace, automobile manufacturing, electronic and electrical, medical and food processing fields. Because of the unique performance advantages of PEEK materials, PEEK products can be widely used in many fields such as petrochemical, electronic and electrical, instrumentation, machinery and automobiles, medical and health, aerospace, military nuclear energy and so on.

The blending of PEEK and polyether can obtain better mechanical properties and flame retardancy; the blending of PEEK and PTFE to make composite materials has outstanding wear resistance and can be used to manufacture sliding bearings, dynamic seal rings and other parts; for PEEK Carbon fiber is filled and modified to make reinforced PEEK composite material, which can greatly improve the hardness, rigidity and dimensional stability of the material.

After adding carbon fiber, PEEK has more outstanding high temperature and thermal resistance. It can be used at 300°C for a long time, and the instantaneous use temperature can reach 360°C. Its rigidity, dimensional stability, and linear expansion coefficient are small, which is close to that of metal aluminum. Carbon fiber has good chemical stability, has strong corrosion resistance to acids, alkalis and almost all organic solvents, and has flame retardant and radiation resistance properties; PEEK plus carbon fiber has excellent sliding wear and fretting wear resistance, especially It can maintain high wear resistance and low friction factor at 300℃; with these excellent comprehensive properties, PEEK plus carbon fiber plastic raw materials are mainly used in automobile and aerospace engine boxes, headlight reflectors, heat exchange parts, valve linings Sets and deep-sea oilfield parts, machinery, petroleum, chemical, nuclear power, rail transit, electronics and medicine have a wide range of applications.
