· Remarks
①MED-1 is low temperature powder.
②This kind of powder is treated without silicone oil or treated with pretty light silicone oil.
③Electrical Grade Magnesium Oxide is non-toxic, but with some dust.Anti-dust respirator and glovesare proposed to use during operation.
④Mainly used in liquid heating elements with wattage loading less than 6w/c㎡.
⑤The elements can stand high frequency machine annealing but requires immediate sealing.
