The hub is the part where the axle is installed in the center of the wheel, which is what people often call "rims" or "steel ring". The wheel hub is easily stained with dirt. If it is not cleaned for a long time, it may be corroded and deformed, causing safety hazards. Therefore, special attention should be paid to the maintenance of the wheel hub. The transmission shaft is connected to the hub and is tightened by a large screw. The hub cover not only looks beautiful after installation, but also has a protective effect of anti-rust and waterproofing.

Functional contribution of mica powder in automotive hub cover materials:

1. The energy-saving effect of lightweight rotating parts such as wheels is equivalent to 1.5 times that of non-rotating parts, which effectively helps lightweight.

4. Improve material dimensional stability and reduce abnormal driving noise.
