fillers are applied in glue and sealant formulation to fill voids. this occupied space is a very important factor in final product quality. fillers used in various applications are: Calcium carbonate, Aluminum trihydrate, barium sulfate, silica, Kaolin clay, soot, Titanium dioxide, graphite, zinc oxide, iron oxide, ballast, saw dust, glass fiber, Mica, copper powder and silver powder.
in addition to price reduction, fillers make gelating tissue stronger and improve adhesive strength. it can be said that fillers are applied in all adhesives production.
in polymer adhesive production, fillers reduce polymer threads shrinkage when hadrening and prevent any stress in gelatin line. in fact, these materials change flow properties before hardening, so they improve ultimate mechanical properties.
