Shivam Polychem Colors Filler masterbatches are concentrates of Calcium Carbonate (CaCO3) or Talc in a polymer base. They offer a convenient way of incorporating CaCO3 and Talc in thermoplastics without contamination by dust. They have perfect dispersion and optimized flow properties ensuring easy processing. The CaCO3 and talc grades used in our filler masterbatches are of excellent quality allowing much higher loading compared to conventional filler masterbatches.
Among main benefits of calcium carbonate concentrates are cost savings, productivity gains, better products quality and environmental advantages.
Calcium carbonate (CaCO3) filler masterbatch or filler master batch is a concentrated mixture of calcium carbonate and other additives which is processed through a heat process into a carrier polymer resin such as PP , LD , LLDPE, or other which is then cooled and cut into granules (pellets) making CaCO3 masterbatch a solid additive for plastics. Opaque Filler /Milky Filler Masterbatches are Calcium Carbonate based Filler Masterbatches for Raffia Tapes (woven sacks), lamination, Moulding, Blown film.
Usage of Calcium Carbonate Masterbatch
The main use of filler masterbatches lies in tapes, which is to provide anti-fibrillation (also known as anti-splitting) properties. There are other advantages as
Calcium carbonate masterbatch alone is normally not used for coloring plastics and, thus, is different from white masterbatches and color masterbatches. However when used together with white TiO2 based masterbatch it not only increases whiteness due to its natural color but also facilitates white pigment dispersion in the polymer matrix contributing to higher opacity.
