Metal replacement-engineering plastics PEEK
Nowadays, aluminum and titanium alloys are commonly used as light metal materials in the machining industry, but in large machines, the lighter the material is, the more energy can be saved. The engineering plastic PEEK, which is comparable to aluminum in mechanical strength, temperature resistance and processing performance, has become the preferred material for mechanical designers.PEEK is a thermoplastic polymer. It is a special engineering plastic with excellent properties such as high temperature resistance, self-lubrication, easy processing and high mechanical strength. It can be manufactured and processed into various mechanical parts, such as automobile gears, oil screens, gear shift starting discs; Aircraft engine parts, automatic washing machine runner, medical equipment parts, etc. It was first applied in the aerospace field to replace aluminum and other metal materials to manufacture various aircraft parts.
The main application of PEEK include:
1. In the field of transportation machinery such as automobiles, especially in the European market, the growth is the fastest. As the automobile industry adapts to the requirements of miniaturization, lightweight and cost reduction, the demand for PEEK resin will continue to grow. There are 44 parts of a European car model that use PEEK plastic instead of traditional metal products.
2. In the field of office machinery parts, when PEEK resin is used to replace metal as their material for the separation claw, special heat-resistant bearing, chain, gear, etc. of the copier, it can make the parts lightweight, fatigue-resistant and oil-free.
3. In the field of medical analysis instruments, PEEK has successfully replaced the traditional titanium metal as an artificial bone material due to its good compatibility with the human body.
