High Purity Magnesium Hydroxide Used for Cable

Magnesium hydroxide begins to dehydrate at 340 ° C. Magnesium hydroxide has high thermal decomposition temperature, 140 ºC higher than the aluminum hydroxide , magnesium hydroxide can be added to the composite material can withstand higher processing temperatures, which will help speed up the extrusion speed, shorten the molding time, but also help Improve flame retardant efficiency. Magnesium hydroxide small particle size, small wear and tear on the device, which will help prolong the service life of processing equipment.Since magnesium hydroxide has many advantages over aluminum hydroxide, the proportion of magnesium hydroxide is increasing. Compared with similar inorganic flame retardants, magnesium hydroxide has a better smoke suppressing effect. Magnesium hydroxide in the production, use and disposal of non-hazardous substances in emissions, but also to neutralize the combustion process of acid and corrosive gases.
