High purity magnesium hydroxide for flame retardant
High purity magnesium hydroxide is generally used in flame retardants, and can also be widely used in chemical industry, metallurgy, home appliances, plastics, rubber, electronics, ceramics, as well as medicine, food and other industries.
Among them, the demand is relatively high in the flame retardant industry, and in the wave-absorbing material industry, because high purity magnesium oxide has high activity and high dispersibility, so it can be easily compounded with polymers or other materials. This composite material has good microwave absorption properties, while not so much as to make the raw material strength, toughness and other indicators of the reduction, and adding fibrous magnesium oxide has a reinforcing effect.
