Mineral fillers and functional fillers are a variety of solid particulate materials that may be irregular, acicular, fibrous or plate-like in shape and which are typically used in reasonably large volume loadings.
The most commonly used particulate fillers are industrial minerals such as silica, talc, calcium carbonate, mica, kaolin, wollastonite, feldspar and barytes.
The choice of filler used in a specific application depends on the physical attributes of the mineral. For example, clay fillers used in polymer systems share some common features because of the plate-like shape of their particles, which results in some stiffening of the rubber compound. This gives much better extrusion and calendering properties (exhibiting low die swell and good dimensional stability) than can be obtained from most other mineral fillers.
