It is chemically combined with three water molecules and has a high melting temperature. Due to the physical properties of this mineral, it has become a basic raw material in the formulation of a multitude of composite materials: rubbers, polyurethanes, polyester, silicones, thermoplastics, cables, etc&#8230; when it comes to improving fire resistance.<\/p>\n<p>The advantages of using aluminium trihydrate are:<\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li><strong>important properties as fire retardant and smoke suppressor.<\/strong>\u00a0Under fire conditions, water vapour is released through an endothermic reaction that acts to cool the surface and displace the oxygen required for combustion. The resulting aluminum oxide carbon barrier makes combustion even more difficult and reduces the smoke density. That is the reason why aluminium trihydrate is becoming the most widely used flame retardant on the market. It is an environmentally friendly mineral. Its thermal decomposition occurs at about 200 \u00b0C, making it suitable for a wide range of plastics and rubber applications.<\/li>\n<li><strong>excelent chemical resistance and physical properties.<\/strong>\u00a0In combination with boehmite it allows us to improve scratch, gloss and stain resistance. It is especially resistant to acids.
