Paper Industry

Kaolin is the most extensively used additive in the manufacturing of paper, primarily as a filler and coating. Kaolin is combined with wood pulp or fiber to generate substantially more paper filler, and thus more paper. It is a cost effective alternative to all wood paper filler, which has become more expensive as demand for paper increases and supply of wood decreases. Kaolin’s primary competition in fillers is calcium carbonate which, though more affordable, has less dramatic results. The particle size of kaolin plays an important role in fillers and coatings as larger particles provide added strength to paper. Kaolin coatings improve paper appearance, giving it varying degrees of gloss, smoothness, brightness, opacity and most importantly printability. Three aspects of kaolin that shape these characteristics are purity, rheology and particle geometry. Kaolin improves printability by providing added ink absorption, ink pigment holdout, lowering linting tendency and increasing roughness.
