high brightness, high dispersion and high cover rate
* Application –
With excellent characteristics of high brightness, high dispersion and high cover rate, Calcined kaolin are widely used in paper, paint, rubber, plastic, printing ink, refractory, electronic, chemical, oil industries, and production of detergent additives, at the same time it can substitute for lithopone and titanium dioxide in part. It can also be modified for the functional requirement as filler.
