MAGNESIUM HYDROXIDE

'Magnesium Hydroxide "STAR BRAND" is a high purity product manufactured directly from seawater by our original technology based
on the longtime experiences.

STAR BRAND #200 is technical grade, contains a little impurity and has high surface activity and so good reactivity.

Magnesium Hydroxide P is pharmaceutical grade, is a product of best purity as raw material.

Magnesium Hydroxide Granular is granular type, so it shows good workability and improves productivity.
