Magnesium Oxide (MGO)

KYOWAMAG® is general grade brand of lightly calcined magnesium oxide, and the reaction will be different by degree of grade. It is used in the vulcanizing agent of synthetic rubber, acid acceptor and formulation of adhesive.

KYOWAMAGⓇ150 is a Magnesium Oxide grade that has a fine particle size and high activity. It is used in synthetic rubbers, including CR and CSM formulations, to improve vulcanization, anti-scorching and acid neutralization. KYOWAMAGⓇ150 can also be used as an additive for polymers.
