FillerTEK® Technology
Engineered Filler
Addressing the concerns of today’s paper producer, FillerTEK technology delivers an increase in filler content of up to five units, while preserving the critical strength and optical attributes of the final sheet. This new technology effectively delivers cost-efficiency to paper producers by allowing them to utilize less expensive raw materials.
Nalco's FillerTEK technology combines several aspects of wet-end chemistry and filler pre-flocculation to make higher filler content achievable. FillerTEK technology is based on increasing the particle size of the filler through a unique method of pre-flocculation, with the net outcome being reduced interference of the filler with fiber-fiber bonding. The filler treatment is carried out on-site with a mill’s existing filler slurry. FillerTEK technology is an ideal fit for paper producers utilizing precipitated or ground calcium carbonate (PCC or GCC), or a blend of the two carbonates as their filler source. Through utilizing the technology, paper producers can expect to achieve a high Return on Investment (ROI). Benefits have been identified in several areas including:
- Reducing fiber cost by 5%
- Maintaining strength properties
- Decreased steam usage at higher filler loadings
