| Superfine Magnesium Hydroxide |
| This product selects good Brucite, and new fire retardant & anti-smoke compound (annual capacity of the first term project is 10000 tons), which are produced by advanced technics of rubbing classification and surface treatment at home and abroad. After tested by relative authorities, its performance of inflaming retarding, anti-smoke, mechanics, craftwork has been proved to reach similar products standard at home and abroad if filled in rubber & plastic products. It is perfect filling materials of inflaming retarding and anti-smoke without any smoke, halogen and social effects of pollution for rubber & plastic products, which can be widely used in materials of EVE, PE cross linked cable, light smoke PVC cable, mine rubber belt, rubber floor for plane, train vessel, and household appliances shell. It is best used for high anti-impact polystyrene HIPS (building industry), ABS and PVC. It is featured with high temperature of thermal dehydration and good processing performance if mixed with macromolecule materials. its cost is just 50% of Magnesium Hydroxide synthesized by brine, which is perfect substitute with fire retardant & anti-smoke compound |
