Alumina Trihydrate for Polymer Filler

For Alumina Trihydrate for Polymer Filler, it mainly works in the heating and decomposition these two stages, when the heating temperature exceeds 200 ℃, the Alumina Trihydrate for Polymer Filler began to heat decomposition, the release of three crystal water. The reaction is a strong endothermic reaction, decomposition per gram of A1 (OH), the heat absorption of 878J, and between 300 ~ 380 ℃, the decomposition rate of the largest, and this temperature range is the decomposition of most polymers temperature.

It is based on the decomposition of Alumina Trihydrate for Polymer Filler when a large number of endothermic. Therefore, when the polymer which contain aluminum hydroxide is heated, the Alumina Trihydrate for Polymer Filler is decomposed by endothermic heat, thereby suppressing the increase of the polymer temperature and reducing the decomposition rate. Secondly, it releases the water vapor when it is decomposed by heat, combustible or corrosive gases, while diluting the decomposition of the polymer produced by a variety of combustible gases, so that fire is more difficult.
