Magnesium oxide powder for electric heating rack

It means that the fused crystalline magnesium oxide blocks are crushed and matched with different particle sizes or numbers in a certain proportion, and directly or modified to be used in tubular electric heating elements as an insulating medium for heat conduction at high temperatures. In the electric heating tube, it mainly plays the role of fixing the central position of the resistance wire, ensuring that the metal shell is not charged (insulation), and conducting the heat emitted by the resistance wire.
