Is Magnesium Oxide Board An Insulating Material?

Magnesium oxide board can usually be used as an insulation material for the following reasons:

Main component characteristics: The main component of magnesium oxide board is magnesium oxide, which has good insulation properties. Its crystal structure is stable, and electrons are difficult to move freely in it, making it difficult for current to pass through, thus possessing the basic characteristics of insulation.

Insulation performance indicators: In general, the volume resistivity of magnesium oxide board is relatively high, usually reaching 10 ¹⁰Ω· m or more, and the dielectric strength is also relatively high, reaching 10kV/mm or more. These indicators indicate that it has good insulation ability and can effectively prevent current from passing through within a certain voltage range, playing an insulation role.

Insulation performance in applications: In practical applications, magnesium oxide sheets are often used in situations where insulation performance is required, such as insulation components for electronic equipment and lining for electrical control cabinets. In these application scenarios, magnesium oxide plates can reliably isolate current, ensuring the normal operation of equipment and personnel safety.

However, the insulation performance of magnesium oxide board may be affected by some factors, such as moisture, impurity content, production process, etc. If the magnesium oxide board is damp, the moisture will reduce its insulation performance; Excessive impurity content may also form conductive channels inside the board, affecting the insulation effect; Poor production technology may lead to uneven internal structure and defects in the board, thereby reducing insulation performance.
