Filling SC Papers with PCC; A Holistic Approach
Evans, B., Wright, R., Haskins, W., Laakso, A-P.
PIRA Conference, Fillers and Pigments for Papermakers, November 9-10, 2005, Atlanta, GA
Topic: Many North American and European supercalendered paper manufacturers are now using precipitated calcium carbonate (PCC) fillers for optical and bulk advantages as well as overall cost savings. To be most effective, the entire paper manufacturing operation should be examined from the pulp/bleach plant to the paper machine to the printing press.
Fillers for Papermakers
Gill, R.; Tappi Wet-End Chemistry Short Course, 2005
Topic: A review of paper fillers, properties and uses with emphasis on functionality.
Assisting Market Growth & Profitability in Both Established and Emerging Markets: The Future Role of Mineral Additives in Improving Company Margins
Mueller, K.; Pulp & Paper Chemicals Outlook, New Orleans, LA February 24-25, 2005
Topic: Overview of coated and uncoated calcium carbonate containing papers; current status and prognosis.
Neutral Groundwood Papers: Practical and Chemical Aspects
Evans, B., Slozer, M.; 5th International Paper Coating Chemical Symposium Proceedings, p 43, 2003
Topic: Minimizing alkaline darkening via the use of a weak/acid chelant (WAC) in the papermaking system allows papermakers to take advantage of the superior brightness and light scattering ability of precipitated calcium carbonates.
Effects of Filler Pigment Type on the Offset Printability of Supercalendered Paper
Ain, R., Cantino, J., Fan. J., Stevens, S., Wright, R.; Pulp & Paper Canada, v 103, No. 3, p 40-44, 2002
Topic: This paper describes the print quality and press runnability of SC papers incorporating scalenohedral PCC, as observed during a commercial scale heatset offset printing trial.
PCC Application Strategies to Improve Papermaking Profitability. Part 1. Thick Stock Precipitated Calcium Carbonate Addition
Haller, T. M., Janson, J. A., Stryker L. J.; 2001 Papermakers Conference, Cincinnati, Ohio, March 11-14, 2001, p 1119-1128, Tappi Press
Topic: In freesheet, precipitated calcium carbonate filler levels now average over 15%. This paper describes options to optimize fiber usage, maximize paper strength and increase machine runnability.
Use of Precipitated Calcium Carbonate (PCC) Fillers to Improve the Brightness and Opacity of Woodfree and Wood Containing Papers.
Gill, R.; Use of Minerals In Papermaking, p 113-132, February 1997
Topic: Paper discusses how precipitated calcium carbonate can affect brightness and opacity of woodfree papers, wood containing SC papers, and paper coatings.
Effect of Papermaking Additives on Sizing
Gill, R.; 1997 Sizing Short Course (Tappi): Course Notes, Session 9,15 p, April 14, 1997
Topic: Course examines the relationship between paper porosity, hydrophobicity, and addition of papermaking additives on internal sizing. Good sizing efficiency requires a balance between maximizing first-pass retention of all additives and minimizing filler/fines agglomeration.

Mill Experience with AT® Precipitated Calcium Carbonate (PCC) in Papers Containing Mechanical Pulp
Ain, R.L., Laleg, M.; Pulp & Paper Canada v 98 n 12 Dec 1997, p 172-176,1997
Topic: Acid-tolerant chemistry, as provided by AT® technology from SMI, allows the use of PCC at neutral pH in mechanical papermaking systems with minimal carbonate dissolution and fiber darkening. The paper includes discussions on techniques and experiences of using PCC with emphasis on paper machine operation, mill processes and quality improvement.
