Many types of fillers, aluminum powder, zinc powder, silver powder and other metal powder may be used as the conductive filler. Cement, fly ash, etc. can be used as fillers. Wood flour, starch and other plant powder can be used as a filler. A small amount of calcium fluoride can be used in polyurethane adhesive and sealant systems; both carbon dioxide absorbing effect.

In general, a fine powder filler or modified fine filler, and a fibrous, platy fillers, the use of a small amount can improve its overall performance, e.g., of an elastomeric polymer (e.g. rubber, polyurethane elastomer _) have a reinforcement effect, increase the modulus, strength, wear resistance, heat resistance, improved dimensional stability, for hard products can suitably improve strength, resistance to aging. However, excessive use of such material is reduced, and the operation difficulty filler content is large. Fillers are the following: Depending on the filling mode can be divided into bulk packing and structured packing. Bulk Packing is one with a certain geometry and size of granules, generally stacked in a random manner in the tower, also known as random packing or particulate filler.
