Magnesium Hydroxide with larger diameter |
Chinese |
[Characteristic]
* As coarse magnesium hydroxide is a heavy powder with low specific surface area, coarse magnesium hydroxide has
excellent flowability.
* As coarse magnesium hydroxide consists of coarse particles with a low aspect ratio, coarse magnesium hydroxide has
high acid resistance and excellent filling properties in resins
* Coarse magnesium hydroxide is highly pure as the total impurities are less than 500 ppm.
* Coarse magnesium hydroxide has excellent insulation performance as especially ionic impurities are low
