Fumed Aluminium Oxide ALuna-80 

Characteristics  

HIFULL ALuna-80 is 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
