"STARMAG" is Konoshima's light-burned Magnesium oxide produced from natural raw materials, seawater and limestone.
They are the highest quality products with fine particles by our particle control technology. We can offer various grades for diverse applications.
high-reactive grade mainly used for vulcanizing agent for chloroprene rubber.
middle/low-reactive grades mainly used for compounding agent or chemical raw material.
High-reactive grade with fine particles.
It has higher purity and whiteness than other grades
Granular grade with easy handling and good workability.
high-reactive grade with surface coating to improve dispersibility in polymer and less adherent on mixing roller.
