According to its shape, it can be divided into powder, globular, flake, columnar, needle-shaped and fibrous fillers.

The fillers used in plastics are classified according to their chemical composition as follows:

 

Oxides: silica, diatomite, alumina, titanium dioxide, iron oxide, zinc oxide, magnesium oxide, antimony trioxide, barium ferrate, strontium ferrate, beryllium oxide, alumina fiber.

 

Hydroxides: aluminum hydroxide, magnesium hydroxide, base magnesium carbonate.

 

Carbonate: calcium carbonate, magnesium carbonate, dolomite, aluminum carbonate basic.

 

Sulfite: barium sulfate, calcium sulfate, ammonium sulfate, calcium sulfite.

 

Silicate: talc, clay, mica, asbestos, calcium silicate, montmorillonite, bentonite, glass bead, glass fiber.

 

Carbon: carbon black, graphite, carbon hollow ball, carbon fiber.

 

Others: zinc borate, calcium borate, sodium borate, barium metaborate, potassium titanate.
