Magnesium hydroxide is an excellent flame retardant for plastic and rubber products. As an environmental protection, as a flue gas desulfurization agent, it can replace alkali and lime as a neutralized agent and heavy metal adsorption agent for acid wastewater. In addition, it can also be used in the electronics industry, the refining of medicine and sugar, for insulation materials and manufacturing other magnesium salt products. Magnesium hydroxide is used as a smoke discharge desulfurization absorbent. Most of the smoke discharge desulfurization and lime gypsum method were used before the 1970s. Due to the secondary pollution of the by -products to the environment, the hydrogen has been used since the 1980s. Magnesium oxide method; acidic wastewater; combined resin flame retardant, which used to use bromine, phosphorus, chlorine, and inorganic salts in the past. Most of these products were used in these products. Magnesium, mainly because magnesium hydroxide hydroxide in thermal plastic resin can increase the dehydration and decomposition temperature above 350 ° C.
The chemical composition of our products, their particle size distribution, the availability of different types of coatings, and even the mastery of the crystal shape of our products: all these parameters are key to the perfect performance of your formulations. Magnesium hydroxide powder is designed to act as an effective flame retardant and smoke suppression additive, achieving high flame retardancy, low smoke emissions and toxic gas absorption without adversely affecting mechanical properties. Its stable processing allows it to be incorporated into polymers at desired loadings without unduly affecting performance characteristics. On contact with fire, it decomposes according to an endothermic reaction, releasing diluent gases at temperatures close to the decomposition of the polymer. That's why we offer a comprehensive product range for this application. We will be happy to guide you through a successful project.
