Calcium Filler Masterbatches

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.

What is calcium carbonate filler masterbatch?

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

 
  •    RAFFIA TAPES :- A wide range of fillers for raffia is offered by us for different applications
  •    HDPE & PP,Low/High denier Fabric.
  •    Lino Bags
  •    FIBC
  •    Tarpaulins
  •    Blown Film:-Used to make liners/carry bags opaque, increase strength and allows loading upto 60%
  •    Furniture:- Compound of strength and economic results
  •    Blow moulding:- For containers,barrels and other articles.
  •    Injection Moulding

Features

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

 
  •    Higher stiffness
  •    Easier processing
  •    Improved weaving ability
  •    Improved anti-blocking properties
  •    Improved weld ability and printability
  •    Reduction of white masterbatch requirement
  •    Lower raw materials cost, as they are more economic than polymer resins.

Useful effect of Calcium Carbonate Masterbatches

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.

 
  •    Calcium carbonate concentrates usually contain from 60% to as high as 90% of CaCO3 in the polymer matrix and are commonly based on polyolefin (PE or PP) resins, though other polymers (PS, EPS, ABS etc.) can be filled as well.
  •    Calcium carbonate filler masterbatches is the most effective cost-saving solution for worldwide plastic processors.
  •    CaCO3 filler masterbatch not only cuts down plastic production costs by replacing a part of virgin polymer during extrusion, injection and blow molding, but also increases output, improves production conditions as well as a number of physical and chemical properties of finished plastic products.
  •    Today advanced calcium carbonate concentrates not only fill but also impart other properties to (improve) plastics. In this case they rather act as functional additives than simply common fillers, and may be referred to as additive masterbatches.
