Most fillers used are inorganic and are usually based on naturally occurring mined minerals that are beneficiated in some cases. Some fillers are made synthetically, usually by precipitation from a solution of soluble salts.
Particle size varies with the filler's specific grade, but can range from relatively coarse particles-- a median particle size of 15 microns or more with 1 to 2 percent retained on a 45 micron screen. Some fillers are sized to very fine particles with a median particle size of well below 1 micron. The precipitated fillers usually have a finer and more narrow particle size distribution than the ground fillers.
1) Widely used in coating powder formulations to modify functional properties, such as hardness, modulus, permeability, corrosion, abrasion, chip resistance, gloss, texture, flammability, and electrical characteristics.
2) Agricultural firms use MINERAL FILLERS in seed coatings to fend off pests and to help improve plant health
