Magnesium Hydroxide for Flame Retardant [MAGSEEDS®]

"MAGSEEDS" is Konoshima's Maganesium hydroxide for flame retardant.
This product is produced from sea water and has been used as HFFR(Halogen Free Flame Retardant) with great reputation.
It can also be used as smoke suppressant in LSZH(Low Smoke Zero Halogen) formula.
We can offer various products depending on surface treatment and particle size.

MAGSEEDS N

MAGSEEDS N is surface treated product by fatty acids.

MAGSEEDS S

MAGSEEDS S is surface treated product by silane coupling agent.
It is suitable for high flame retardance formula for good mechanical properties such as tensile strength, scratch resistance with coss-linked resin.

MAGSEEDS EP

MAGSEEDS EP is the product with special surface treatment to improve acid/water resistance.
Especially suitable for Epoxy molding compounds.

MAGSEEDS W

MAGSEEDS W is produced from Brucite with our original process of pulverising and surface treatment.
