Magnesium Hydroxide Flame Retardant 85% to 95%, MgO 60% to 66%.
Utilizing the natural raw brucite, we developed magnesium hydroxide superfine powder and flame retardant series. After surface modification, the product keeps well dispersivity and fluidity in resin, and avoids the prolem of poor acid resistance. Also, the mechanical strength and flame retardancy of the material get maintained. We also have various surface treatment methods according to customers' request.
Activity of magnesium hydroxide flame retardants widely used in rubber, chemicals, building materials, plastics (polypropylene, polyethylene, PVC, EPDM rubber) and electronic, unsaturated polyester and paint, coatings and other polymer materials China, especially for mining duct coated fabric, PVC the whole core conveyor belt, fire-retardant blankets, tarpaulins, PVC wire and cable materials, mining cable sheath, cable accessories flame, smoke and anti-static, can replace the aluminum hydroxide with excellent flame-retardant effect.
Attributes
Exellent performance on flame retardancy and smoke abatement.
Good heat stability, decomposition temperature at 330, especially suitable for resin processed in relative high temperature.
Low toxicity, no smell
Large amount of vapor is produced during combustion, the heat is taken away and the temperature drops.
The hardness is less than that of aluminum trihydrate, thus longer equipment life.
