This kind of high whiteness alumina trihydrate can be soluble in strong base or acid solution.It is stable in the environment under 200 Celsius degree .But it can decompose into alumina and release water when the temperature is going high above that temperature of 200 degree.
It is widely used as flame retardant filler to be making products like solid surface,BMC(bulk molding compound),SMC(sheet molding comound),glassfiber reinforced plastics products,etc.Our products have uniform granularity and are made with advanced equipments and technology.The particle shape is much more close a ball size with the benefits of low viscosity,low oil absorption volume.It can also improve affinity with the high polymer system and flame retardance of the products.
