Advantages of PEEK gears: reduce noise, low density, lightweight; reduce inertia force distance; excellent chemical corrosion resistance; outstanding resistance to grease and automotive fuel performance; low moisture absorption, no expansion, reduced strength; high wear resistance, longer service life; better technology for bonding with metals and other plastics; injection molding processing reduces costs. PEEK has the heat resistance of thermosetting plastics, chemical stability, and the molding processability of thermoplastic plastics. The long-term use temperature of PEEK is about 260-280℃, the short-term use temperature can reach 330℃, and it can withstand high pressure up to 30MPa, making it a good material for high temperature seals. PEEK products are suitable for use in various harsh working conditions. PEEK also has excellent properties such as good self-lubrication, easy processing, stable insulation, and resistance to hydrolysis, making it widely used in aerospace, automotive manufacturing, electronics, medical, and food processing industries.
