The profile of relationship between particle size and performance of ATH

The particle size of aluminum hydroxide has a great relationship with the performance. With good dispersion in the polymer, the smaller the particle size, the larger the specific surface area and the better the flame retardant effect. How to guarantee the small particle size of aluminum hydroxide crystals itself and the consistency of the product during the drying, depolymerization and classification process. This will be challenging for both powder process and equipment. At present, AVANT's ultra-fine high white series products have a D50 of 1.2-2.0 microns and a narrow particle size distribution, which are suitable for the production of various rubber and plastic products.
