PEEK has the characteristics of high temperature resistance, high wear resistance, high tensile strength, and good flame retardancy. It also 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.
The hardness of PEEK material depends on whether it is pure material or glass fiber or other additives. Generally, the Shore D of pure PEEK material is generally 88, and the PEEK material reinforced by glass fiber is generally Shore D89, and PEEK reinforced by carbon fiber The material is generally Shaw D91. But different crystallinity will also have different hardness at that time.
PEEK sheet, the Chinese name is polyether ether ketone sheet, is a new type of engineering plastic sheet extruded from PEEK raw materials. PEEK board has good toughness and rigidity, it has excellent fatigue resistance, and maintains good toughness and material stability at high temperatures. With these excellent comprehensive properties, the parts processed by PEEK plates are widely used in automobile connectors, heat exchange parts, valve bushings, deep-sea oilfield parts, and in machinery, petroleum, chemical, nuclear power, rail transit, electronics and medicine, etc. There are a wide range of applications in the field.
The peek material can be injection molded. PEEK is a high-temperature special engineering plastic and needs to be maintained at about 350 degrees. This requires the heating section of the injection molding machine barrel to continuously and stably provide a heating temperature above 350 degrees. The melting temperature of the peek material at high temperature is relatively high, and the viscosity in the molten state is relatively large, and the pressure required for injection molding is higher, and the wear of the screw is greater. In addition, peek injection molding requires heating, which is different from ordinary injection molding. It is recommended to find a manufacturer that specializes in peek injection molding to avoid certain technical risks.
Peek is a special engineering plastic with excellent properties such as high temperature resistance, self-lubricating, easy processing and high mechanical strength. It can be manufactured and processed into various mechanical parts, such as automobile gears, oil screens, gearshift starting disks; aircraft engine zero Parts, automatic washing machine runners, medical equipment parts, etc.
The color of pure PEEK is generally light yellow, modified (carbon fiber, graphite) PEEK is generally black, PEEK with ceramics is generally white, and PEEK with glass fiber is generally brown.
