The hardness of PEEK material depends on whether it is pure material, added with glass fiber or other additives. Generally, the Shore D of pure PEEK is 88, the Shore D of glass fiber reinforced PEEK is generally D89, and the Shore D of carbon fiber reinforced PEEK is generally D91. However, different degrees of crystallinity can also result in varying degrees of hardness.

PEEK plastic exhibits excellent mechanical properties and is highly resistant to chemicals and thermal degradation, making it an ideal material for injection molded products. PEEK plastic can resist high temperatures and long-term liquid immersion well, and is very durable in harsh environments. In many special fields, it can replace traditional materials such as metals and ceramics.

PEEK board is a new type of engineering plastic board extruded from PEEK raw materials. PEEK board has good toughness and rigidity, excellent fatigue resistance, and maintains good toughness and material stability at high temperatures. With these excellent comprehensive properties, PEEK board processed components are widely used in automotive connectors, heat exchange parts, valve bushings, deep-sea oilfield parts, and have a wide range of applications in machinery, petroleum, chemical, nuclear power, rail transportation, electronics, and medicine.

PEEK materials have good aging resistance, and will not become brittle and aging like ordinary plastics after long-term exposure storage. The packaging is intact and the storage conditions are suitable. PEEK material will not deteriorate and has a long shelf life, so there is no need to worry about shelf life issues.

PEEK carbon fiber can be stored at room temperature, which allows for the production of large structures without time constraints. PEEK carbon fiber has a high impact damage tolerance, and its residual compressive strength after impact is greater than that of thermosetting composite materials. Thermoplastic composite materials also have good thermal compression strength and can replace thermosetting composite materials to a certain extent

PEEK polyether ether ketone is a special engineering plastic used in automobiles, aviation, machinery, etc. It has high mechanical properties, excellent dimensional stability, high wear resistance, high temperature resistance, chemical resistance, hydrolysis resistance, and so on.
