What is PEEK？
PEEK and its modified composite materials show excellent performance under high temperature and high humidity conditions. PEEK have excellent chemical corrosion resistance, self-lubricating, and wear-resistant properties, so it has become the most ideal material to replace copper alloys and ordinary rubber. Compared with them, PEEK has longer service life which can reduce equipment operating costs, improve equipment operating reliability.
High Temperature Performance
PEEK’s performance can remain stable in the temperature range from -196°C to 260°C. Under extreme working conditions, it can withstand 300″C for a short time. The performance of PEEK is still reliable even in high temperatures of several kilometers underground work environment.
High Strength and Wear Resistance
Compared with other plastics, PEEK is resistant to compression, impact and also have good fatigue resistance. PEEK is durable in mechanical equipment and wear-resistant environments.
Double the Service Life
PEEK sealing solutions can improve the part service life. Some domestic chemical companies use the PEEK5600FE20 polytetrafluoroethylene modified material designed by JUNHUA PEEK to replace the original material, the service life of the wear parts can even be extended by 1.3-3 times.
Corrosion Resistance
PEEK is chemically inert, and has no reaction to most acids, oils, greases and all other organic and inorganic solvents or enzymes, and can still maintain good strength and dimensional stability.
Self-lubricating
PEEK has low friction coefficient, low running resistance, can be used without oil in some working conditions. The equipment is cleaner, thus improving process reliability, improving energy efficiency and saving costs.
More dom in Design
Injection molds can be used for rapid injection molding of large quantities of complex special-shaped parts, and the cost is low compared to machining.
