BURGESS OPTIWHITE UF - Technical Data Sheet



BURGESS OPTIWHITE® UF is a state of the art extender with superior brightness, delivering unsurpassed wet and dry opacity. It is derived from ultrapure hydrous feedstock, then further processed using flash calcination. During flash calcination, particles remain separated which prevents the formation of aggregates, allowing for fine particle distribution. These fine particles have internal air voids that cannot be wet out thus achieving superior light refractivity.
