Magnesium hydroxide is a new type of environmentally friendly flame retardant filling type, through thermal decomposition releases combined water, absorb a large number of latent heat, in order to reduce its fill of synthetic materials in the surface temperature of flame, can inhibit polymer decomposition and the combustible gas generated by the effect of cooling. Decomposition of magnesium oxide is good refractory material, can also help improve the fire resistance performance of composite material, at the same time it also can be used as a release of water vapor smoke suppression agent. Magnesium hydroxide is recognized in the rubber industry which has the function of flame retardant and smoke suppression, filling the triple excellent flame retardant. Widely used in rubber, chemical industry, building materials, plastics and electronics, unsaturated polyester and paint, paint and other polymer. Especially for mine air duct, PVC coated cloth whole core conveyor belt, flame retardant aluminous model board, tarpaulin, PVC wire and cable, mine cable sheath, cable accessories smoke flame retardant, antistatic, but instead of aluminium hydroxide, it has excellent flame retardant effect. Compared with other inorganic flame retardant type magnesium hydroxide, a better smoke suppression effect. Magnesium hydroxide in the process of production, use and waste no harmful substances emissions, but also can neutralize acid and the corrosive gas generated in combustion process. With the base resin has good compatibility, is excellent flame retardant thermoplastic resin and rubber products, adhesive often used to add flame retardant agent or flame retardant filler. Industry used in the manufacture of magnesium salt, active magnesium oxide, medicine, fine ceramics, insulation materials, refined sugar, flue gas desulfurization agent, oil anticorrosive additive, acid waste water neutralization agent, color TV picture tube cone glass coating, etc.

Magnesium hydroxide flame retardant in reducing the amount of smoke burning plastic is very effective. Some important factor of magnesium hydroxide flame retardant performance summarized below:

1. The decomposition of magnesium hydroxide flame retardant endothermic temperature about 330 ℃ (and trihydrate alumina endothermic decomposition temperature about 220 ℃), isolating heat from the combustion matrix, slow down the speed of plastic pyrolysis.

2. The magnesium hydroxide flame retardant absorbing material water starts to decompose the easy burning material for the existence of gas phase transfer.

3. Magnesium hydroxide and its decomposition product relatively high heat capacity to reduce the thermal energy can be used for degradable plastics.

4. The thermal decomposition of magnesium hydroxide product through the formation of carbon increases the isolation effects of plastic from the heat source.

5. Add processing of magnesium hydroxide flame retardant plastic related high filler content usually as a solid diluent.

Our company is specialized in the production of small inorganic flame retardant - magnesium hydroxide granularity (200-8000 mesh), particle size uniform, high hematocrit Peng Hua degree good, easy to mix in all, the advantages of the flame retardant effect is good, can significantly improve the flame retardant and smoke suppression of polymer, effect of melt drop resistance, and at the same time have the filling effect. Suitable for rubber, nylon, plastic, paint, paint, paper industry such as flame retardant filler
