· Remarks
①MED-3 is Mg0 powder for Aluminum tubes.
②This kind of powder id treated with heavy silicone oil.
③Electrical Grade Magnesium Oxide is non-toxic,but with some dust ,Anti-dust respirator andgloves are proposed to use during operation.
④Mainly used in liquid heating elements with wattage loading less than ≤6w/c㎡.
⑤Elements stuffed with this material are proposed to be annealed at 250℃,and don’t require sealing.
⑥Electrical Grade Magnesium Oxide should be stored in places,and are suggested to be used out withing 6months after delivery.
