Activated alumina, also known as reactive alumina, is a highly porous material made from aluminum hydroxide. With advantages such as many micro pores, large surface area, and good dispersion performance, activated alumina has a high affinity for water, impurity and activated catalyst. By the applications of balls, it can be divided into three types, including activated alumina adsorbent, activated alumina desiccant and activated alumina catalyst carrier.
Champack is a Chinese activated alumina manufacturer and supplier. We provide high quality activated alumina adsorbent for defluorination, activated alumina adsorbent for drying, activated alumina for hydrogen peroxide to customers all over the world. Our products are used for a wide range of adsorbent, descant, and catalyst applications. Due to their reliable quality, stable performance and economical prices, they are highly sought after in the petrochemical, chemical and fertilizer industries.
