Magnesium hydroxide has good flame retardant effect
Share to:
Heat absorption: Magnesium hydroxide decomposes when heated (340-490°C), absorbing a large amount of heat energy, thereby reducing the temperature of the surface of the material and playing a flame retardant role
The application of ultrafine magnesium hydroxide powder in electronic materials has some significant advantages,
Advantages:
Thermal stability: Magnesium hydroxide ultrafine powder has high thermal stability, suitable for electronic materials, can be used as a heat stabilizer
.
Flame retardant: In electronic and electrical equipment, magnesium hydroxide ultrafine powder can be used as a flame retardant material to improve product safety
.
Electrical insulation: Due to its good electrical insulation properties, magnesium hydroxide ultrafine powder can be used as an insulating material for electronic equipment.
