Opacitex™ calcined kaolin
Product Description
Opacitex™ is a calcined kaolin specifically designed for filling uncoated groundwood papers. The pore structure of Opacitex™ has been optimized to yield maximum light scatter and to control ink vehicle penetration. The result is improved opacity and sheet gloss, as well as reduced ink strike through and print show through in lightweight groundwood grades. It also has higher light absorption for higher opacity and slightly larger particle size which contributes to its enhanced retention compared to conventional calcined kaolin.
Application
Groundwood grades such as newsprint, lightweight directory and groundwood specialties, can be improved by using 2-6% of Opacitex™ as filler.
Shipping
Opacitex™ is available in dry bulk, sparger and bag forms. For more information regarding shipping or
