Fumed Aluminium Oxide ALuna-100

Characteristics  

HIFULL ALuna-100 are fine-particulate, fumed aluminium oxide (AL2O3) powder

with high specific surface area. The positive surface charge of fumed alumina enables it can be used in many applications with special properties and functions.

Applications 

※ Ceramic coating for separators in Liion batteries to

increase thermal stability & safety; Improve conductivity & reversible capacitance when applied in anode of Li-battery;

※ Improve chargeability & flow ability for powder coatings & printing ink;

※ Applied in different types of thermal board

※ Enhance charge adsorption of meltblown electret masterbatch;

※ Applied in fluorescent coating powders in lighting industry to uniform light output, reduce light attenuation and UV harms;

※ Super fine powder enables to improve gloss & ink absorption of papers

Properties & Functions

※ High specific surface area and high purity

※ Low bulk density

※ super fine particle size & good dispersion performance

※ Positive surface charge
