Industrial Applications - Magnesium Oxide
MagChem 10
Combines low reactivity, high purity and fine particle size and is used to make magnesium salts . . .
MagChem 30
Used extensively as a magnesia source because of its high purity, controlled reactivity and relative economy . . . (U.S. Distributor: Premier Chemicals, LLC)
MagChem 35
Used in the manufacture of construction products, fuel additives and rubber compounding due to its intermediate surface area and fine particle size . . .(U.S. Distributor: Premier Chemicals, LLC)
MagChem 40
Well suited for rubber formulations, particularly neoprene, as a filler, anti-caking agent, and pigment extender . . .(U.S. Distributor: Premier Chemicals, LLC)
MagChem 50
Ideal for chemical reactions where reactivity and rapid conversion to Mg(OH)2 are required due to its very high surface area . . .(U.S. Distributor: Premier Chemicals, LLC)
MagChem P-98
Due to slow reactivity, MagChem P-98 is ideal for use in refractory and ceramic applications where a slow, controlled chemical rate is required . . .
