Paper & Pulp


Talc are used in the pulp, paper and board industry as a pitch and
sticky control agent,
as runnability aid, as a coating pigment in
paper industry, and as a multifunctional filler.
In certain specialty papers such as colored papers and labels, talc’s
special properties improve quality and productivity.
Talc reduces paper surface friction,crepe wrinkles and core burst
problems, prevent wear and abrasion on reels / cutters and other
converting equipment and give paper a smooth softer feel by
improving paper touch.
1. Virgin pulp & Paper production:
Pulp cleanliness is critical for runnability in both pulp and paper production. In virgin pulp production, the main cause of
runnability problems is wood pitch which forms deposits in screens, filters, pipes and storage tanks leading to excessive
broke and bad dewatering.
Talc can be used in both the pulp and paper production process to adsorb pitch, preventing agglomerations that form
deposits in operating systems.
Talc keeps the process and the finished pulp clean thus improving pulp quality, preventing deposits in the equipment,
reducing downtime and broke on the paper machine. Talc is also worked as a cost effective fiber substitute, extending wire
and machine fabric life.
Talc is chemically inert, allowing producers to work with closed water circuits, reducing water consumption and river
pollution.
Talc is also an excellent, cost-effective TiO2 extender, improving opacity and the quality of the finished paper.
2. Recycled Fiber (RCF) & Deinked Pulp (DIP) production:
In RCF and DIP pulp production, the main cause of runnability problems are ‘stickies’ such as wood resin, adhesives,
inks, plastics, binders and hotmelts, which forms deposits in screens, filters, pipes and storage tanks leading to excessive
broke and bad dewatering.
Talc are natural stickies control agents which can be used to remove and neutralize stickies throughout the pulp and paper
production process. Also, by using talc, mills can work with closed water circuits – reducing river pollution and water
consumption.
Talc is also used as pitch and stickies control agent in Newsprint, Tissue Papers production, printing and writing paper
production and packaging applications (like container board, solid board, kraft paper, wrapping paper) etc.
