The important role of Magnesium Oxide in brake pads
In the automotive industry, brake pads are one of the key safety components, directly related to the safety of drivers and passengers. The addition of Magnesium Oxide has brought various performance improvements to brake pads.
1. Magnesium oxide can increase the decomposition temperature of resin and reduce thermal degradation.
2. Magnesium oxide can stabilize the friction coefficient.
3. Magnesium oxide can improve the wear resistance of friction materials. Brake pads will constantly rub against the brake disc during use, and good wear resistance can extend the service life of brake pads, reduce replacement frequency, and lower usage costs.
4. Magnesium oxide can also improve the high temperature resistance of brake pads. When driving at high speeds or braking for long periods of time, brake pads generate a large amount of heat, and their high temperature resistance allows them to maintain good performance even at high temperatures, preventing them from failing due to high temperatures.
When selecting magnesium oxide for brake pads, the following details cannot be ignored. Magnesium oxide used for brake pads has high requirements for product content, particle size distribution, heavy metals, fineness, whiteness, etc. For example, the magnesium oxide content for friction material brake pads should be ≥ 93%, CaO ≤ 1.5%, fineness 325 mesh, and the requirement for silicon dioxide should be less than 0.02. Both heavy and light magnesium oxide can be used for brake pads, but the amount of heavy added is greater and the amount of light added is less. Relatively speaking, products made from lightweight magnesium oxide are more stable, have a higher pass rate, and have better quality.
