We are the manufacturer of the below products: 1. Brucite Mg(OH)2 (use in ACP as Flame Retardant additives, fertilizer, flue gas desulfurization, waste water treatment, etc ) with MgO53%-64% , 2. Magnesium oxide 80%-96% ï¼?used in flue gas desulfurization, fertilizer, animal feeds,etc), it is also called Caustic Calcined Magnesite , with own brucite and magnesite mine with lower SIO2 and Fe2O3 content. Brucite Mg(OH)2 can be used in Alumium composite panel as flame retardant additive. Magnesium hydroxide environmental protection halogen-free flame retardant is a common flame retardant, in addition to flame retardant and smoke elimination performance, and high dehydration temperature, suitable for processing high temperature PP and other polymer flame retardant modification, but also make flame retardant plastic easy to reuse. Representatives of the application of inorganic flame retardant type magnesium hydroxide by chemical decomposition heat absorption and put hot water dilution mass fraction of oxygen in the air, forming insulating layer on the surface of a polymer flame retardant effect of magnesium oxide play are formed by decomposition with non-toxic, smoke, and decomposition product inhibition (aluminum oxide, magnesium oxide) series of chemical stability, so do not produce secondary damage. Aluminum-plastic composite board, referred to as aluminum-plastic board, refers to a 3-layer composite board with plastic as the core layer and aluminum on both sides, and the surface of the product is covered with decorative and protective coating or film (otherwise known as coating) as the decorative surface of the product. Selecting flame retardant core material, the combustion performance of the product reaches the non-combustible grade (B1) or non-combustible grade (A); At the same time, other performance indicators must meet the technical requirements of aluminum - plastic board. So brucite (natural magnesium hydroxide) is the best flame retardant additive.
