minerals is a finely divided inert material (such as pulverized
limestone, silica, or colloidal substances) sometimes added to Portland
cement paint or other materials to reduce shrinkage, improve
workability, or act as an extender.
Physical characteristics of a filler
include mean particle diameter, particle size distribution, aspect
ratio, surface area, dispersibility, and inherent colour.
fillers increase the temperature resistance of polymers such as
polypropylene and polyamides, allowing them to compete with more
expensive materials such as ABS or PBT, respectively, in applications
such as automotive interiors.
company in Atlanta
excited to bring advanced carbon removal technology to the marketplace
because it will allow us to effectively transform coal ash from a ‘waste
byproduct that is landfilled’ into a mineral filler product that can be
recycled into concrete and other products, thereby reducing the solid
waste stream and utilizing a valuable natural resource.
This company intends to
commercialize the technology through development and operation of
facilities across the country that are designed to remove carbon from
the fly ash, rendering a high quality, enhanced fly ash product.

where it improves cold flow properties and cohesion, and stabilizes pH.

in Chinese consumption of kaolin, precipitated calcium carbonate (PCC),
ground calcium carbonate (GCC) and talc has been significant over the
last decade, closely reflecting the booming demand for paper, plastics
and paint in the Chinese economy.
extender and filler mineral consumption for paper applications is
estimated at 26.4 million tonnes, with Western Europe accounting for an
estimated 47% of the total, followed by North America, with an estimated
28% share, and the Asia-Pacific region with 24% of the total.
Competition among mineral fillers continues to be strong in the paper
industry. Precipitated calcium carbonate (PCC) and ground calcium
carbonate (GCC) continue to take market share from kaolin fillers across
most paper grades.
