Aluminum hydroxide filler – Catalyst carrier Catalyst Support Alumina Catalyst support Activated alumian balls

Aluminum hydroxide filler

The aluminum hydroxide filler is a white powder, which is easily soluble in a strong alkali strong acid solution, and is stable below 200 ° C. It decomposes into alumina and releases moisture when it exceeds 200 ° C. This product is mainly used as a filler in low-voltage insulation devices, such as artificial marble, BMC, grille, plastic, SMC sheet and FRP, etc. It is mainly used as fire-retardant insulation products. The company’s product size is evenly matched, using the most advanced equipment and technology, so that the product particle shape is closer to the spherical shape, so that the viscosity oil absorption rate is greatly reduced, and the product affinity and flame retardancy are improved.
