Abstract
Paper properties are affected by the application of filler material in a paper sheet. This research offers an alternative precipitated calcium carbonate (PCC) filler for use in copy paper sheets. The comparison of commercial PCC with a laboratory produced hybrid PCC follows. The hybrid PCC is made from the precipitation reaction between a low grade anhydrous calcium hydroxide and gaseous carbon dioxide. Copy paper is made from Columbian Eucalyptus and 80% Peace River hardwood 20% Domtar Q90 softwood fiber blend. The hybrid PCC and a commercial PCC are added to the paper sheet. The paper properties are analyzed and interpreted. The hybrid PCC has no statistical difference in mechanical strength of the paper sheet against a commercial PCC. Both PCC's researched have a statistical difference in lower mechanical strength when compared to commercial copy paper.
