Magnesium hydroxide is a new type of filled flame retardant. It releases bound water when it is thermally decomposed absorbs a large amount of latent heat to reduce the surface temperature of the synthetic material it is filled in the flame. The generated combustible gas cools. Magnesium oxide produced by decomposition is a good refractory material can also help improve the fire resistance of synthetic materials. At the same time, the water vapor it emits can also be used as a smoke suppressant. Talc Masterbatch
Magnesium hydroxide is recognized as a flame retardant with three functions of flame retardancy, smoke suppression filling in the rubber plastic industry. It is widely used in rubber, chemicals, building materials, plastics electronics, unsaturated polyester (SMC, BMC), paints, coatings other polymer materials.
Especially for mine air duct coating cloth, PVC whole core conveyor belt, flame-retardant aluminum-plastic plate, flame-retardant tarpaulin, PVC wire cable material, flame-retardant, smoke-eliminating anti-static of mining cable sheath, cable accessories , Can replace aluminum hydroxide, has excellent flame retardant effect. Magnesium hydroxide has been widely used in EPDM, chlorinated polyethylene (CPE), polypropylene PP, polyvinyl chloride PVC, polyolefin material (EVA thermoplastic material), unsaturated polyester, flame retardant Master batches, fire-retardant cables, flame-retardant cables, flame-retardant conveyor belts, flame-retardant rubber strips, flame-retardant aluminum-plastic panels, electrical insulation materials, flame-retardant rubber products flame-retardant engineering plastics.
Magnesium hydroxide has no harmful emissions during production, use disposal, it can also neutralize acid corrosive gases generated during combustion. When used alone, the dosage is generally 40%~60%. It has good compatibility with the base resin is an excellent flame retardant for thermoplastic resins rubber products. It is often used as an additive flame retardant flame retardant filler in adhesives. The reference dosage is 40 parts. Industrially used to manufacture magnesium salts, activated magnesium oxide, medicines, fine ceramics, thermal insulation materials, sugar refining, flue gas desulfurizers, oil anticorrosive additives, acid-containing wastewater neutralizers, color TV tube cone glass coatings, etc.
The market growth is mainly due to the increased demand for plastics in LED lights, light radiators, electric vehicles, medical equipment light vehicles. Currently, the thermal conductivity additives used in the thermally modified plastics industry generally include zinc oxide, aluminum oxide, magnesium oxide, boron nitride.
