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.
At Shivam we offer variousl grades of CaCO3 filler mastrebatch for non-woven fabric.
There are a number of benefits of use of CaCO3 fillers in non-woven fabric intended for hygiene, medical, personal care, geotextile, industrial and many other applications.
Adding filler CaCO3 masterbatch into nonwoven materials can improve matte, enhance opacity, increase strength, and provide a cotton-soft feel for comfort, all while reducing your carbon footprint.
A filler masterbatch disperses well in resins and incorporates easily during extrusion.
Calcium carbonate masterbatches based on PP are widely used in plastics industry for manufacturing furniture and household appliances, containers, boxes, buckets and so on.
Among the main processing and product quality benefits of use of CaCO3 Filler masterbatch in injection-moulded products are
As a new market trend, calcium carbonate filled PP Masterbatch proved to be a good substitute for polystyrene and ABS in applications where scratch-resistance is not a requirement. There is no need to modify existing injection molding machines or significantly change machine settings. Depending on existing formulation and specific product application plastic processor can add up to 50% of filler masterbatch into PP resin.
Adding CaCO3 into original polymer formulations is the most economical way to improve the properties of LDPE, LLDPE and HDPE films and sheeting.
The following product benefits will be achieved:
Many interesting developments have taken place in the film industry over the past few years due to new improved resins and the increased capability of extrusion lines.
Technical progress must however be subject to the cost factor and the use of mineral modifiers, especially calcium carbonate can play an important role. Most polymers are ductile but may become brittle under certain circumstances.
One of the main issues the producers of weaving tapes (yarn) and twine face during production is a so called fibrillation effect – an uncontrolled splitting of stretched PP/PE yarn (tape). Using calcium carbonate in the composition helps to reduce or completely avoid fibrillation. Slight modification of your original formula by adding 3-4% of calcium carbonate filler masterbatch is enough to solve the problem.
