Compared with gears made of other materials, what are the advantages of PEEK gears?

The main properties of PEEK material are as follows:

1. High temperature resistance, good thermal stability, ultra-high heat resistance, HDT above 315 degrees Celsius, UL continuous use temperature of 260 degrees Celsius.

2. Mechanical properties PEEK is a balanced plastic with both toughness and rigidity. In particular, its excellent fatigue resistance to alternating stress is the most outstanding among all plastics, comparable to alloy materials.

3. Self-lubricating PEEK has outstanding sliding properties among all plastics, and is suitable for applications that strictly require low friction coefficient and wear resistance. In particular, the self-lubricating performance of PEEK modified by mixing carbon fiber and graphite in a certain proportion is better.

4. Chemical resistance (corrosion resistance) PEEK has excellent chemical resistance. Among common chemicals, only concentrated sulfuric acid can dissolve or destroy it, and its corrosion resistance is similar to that of nickel steel.

5. Flame retardant PEEK is a very stable polymer. A sample with a thickness of 1.45mm can reach the highest flame retardant standard without adding any flame retardant.

6. Peeling resistance PEEK has good peeling resistance, so it can be made into thinly coated wires or electromagnetic wires, and can be used under harsh conditions.

7. Radiation resistance The ability to withstand high radiation is very strong, surpassing the Polystyrene with the best radiation resistance among general resins. It can be made into a high-performance product that can still maintain good insulation ability when the gamma irradiation dose reaches 1100 Mrad.

8. Hydrolysis resistance PEEK and its composite materials are not chemically affected by water and high-pressure water vapor. Products made of this material can still maintain excellent characteristics in continuous use in high-temperature and high-pressure water.
