Filler Masterbatch is widely used in plastics industry for many economic benefits. Filler Masterbatch (or Calcium carbonate CaCO3 Filler Master batch) is compound of calcium carbonate powder and other additives, based on polymer carrier resin. This raw material normally is used for filling in plastics to replace a part of virgin polymer that is very expensive. It is the reason that Filler master batch brings cost savings solution to plastic manufacturers. Filler Masterbatch not only benefits to plastic manufacturers by keeping production costs down by replacing a part of the virgin polymer , but also improves production conditions, increases output. It increases calcium carbonate loading, make easier pelletization, cleaner manufacturing environment as well as many other physical and chemical properties of ended plastic products.
