Magnesium hydroxide
for flame retardant Magseeds series

Magseeds is a halogen-free flame retardant with low smoke emission. Magseeds is an appropriate product to obtain a polymeric material
of LSZH (Low Smoke Zero Halogen) because Magseeds renders a polymeric material flame retardant and also has a great effect on
smoke suppression.


(Magsseds N / S)
* Magseeds N / S is made of monodisperse particles shaped like hexagonal plates of approx. 1um, and Magseeds N / S can be used for
applications requiring high flame retardancy or high resin properties.
* Magseeds N / S has excellent dispersibility in resins because it is uniformly surface-coated.
* As Magseeds has different grades which are surface-treated with higher fatty acid based agents and Silane coupling agents, it can
meet various resin compositions.
* As the raw material is seawater, the resource is limitless, thereby enabling a stable supply.

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

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