Magnesium carbonate

MAGNESIUM CARBONATE

Konoshima's Magnesium carbonate is produced from seawater with our original process.

GOLDSTAR®

Mainly used for natural rubber to improve elasticity as keeping its translucency.

HEAVY

Easy handling because of low bulk density.

GRANULAR

Easy handling and good workability, produced without any binder.
