What is PEEK board, PEEK board application
PEEK board It is a high-temperature thermoplastic, has a high glass transition temperature (162 ° C) and melting point (358 ° C), load thermal deformation temperature up to 332 ° C (30% glass fiber or carbon fiber reinforced trademark), can be used at 260 ° C for a long time, Compared with other high temperature resistant plastics such as PI, PPS, PTFE, PAI, PPO, etc., the upper limit of operating temperature is nearly 60℃ higher;
PEEK resin not only has better heat resistance than other high temperature resistant plastics, but also has high strength, high modulus, high fracture resistance and excellent standard stability. PEEK resin can maintain high strength at high temperature, its bending strength at 200℃ reached about 24MPa, PEEK plate bending strength and compression strength at 260℃ still have 15 ~ 19MPa; The rigidity of PEEK resin is large, the standard stability is good, the linear expansion coefficient is small, and it is very close to the metal aluminum material.
Has excellent chemical resistance character, in general chemicals, only concentrated sulfuric acid can dissolve or destroy it, its corrosion resistance is similar to nickel steel, together with its own flame retardant, less smoke and toxic gases released under flame conditions, strong anti-radiation ability; PEEK resin has good resistance, excellent fatigue resistance to alternating stress is the best in all plastics, and can be compared with alloy materials;
PEEK resin has excellent conflict characteristics, excellent resistance to sliding wear and fretting wear, especially PEEK board can maintain high wear resistance and low conflict coefficient at 256℃; PEEK resin is easy to extrusion and injection molding, processing function is excellent, high molding efficiency. In addition, PEEK also has good self-lubrication, easy processing, stable insulation, hydrolysis resistance and other excellent functions, PEEK board has excellent induction function, good mechanical function, high temperature resistance, chemical resistance, making it the most common high-grade plastic.
