Magnesium Hydroxide for Flame Retardardant MAGSEEDS Series

Magseeds is a halogen-free flame retardant with low smoke emission.
Magseeds is an appropriate product for obtaining a polymeric material of LSZH (Low Smoke Zero Halogen) because it not only renders a polymeric material flame retardant but also greatly suppresses smoking.

Magseeds N / S

Magseeds N / S is made of monodispersed particles in the form of approx. 1um. It can be used for resin applications that require high flame retardancy and superior physical properties.
Magseeds N / S has excellent dispersibility in resins because it is uniformly surface-coated.
Since Magseeds comes in different grades that are surface-treated with higher fatty acid based agents and silane coupling agents, it can meet various resin compositions.
Since the raw material is seawater, the resource is limitless, thereby enabling stable supply.

Magseeds EP

Magseeds EP is made of monodisperse particles of approx. 3um and has excellent flowability when formulated in resins.
As Magseeds EP is surface-treated with inorganic treatment agents, Magseeds EP can be used in fields requiring water resistance and acid resistance.

Magseeds W

Magseeds W is a product manufactured by pulverizing and surface-treating of brucite ores by our original method.
