What is White masterbatch?

es White masterbatch or White masterbatch is a concentrated mixture of titanium dioxide 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 White /Milky White Masterbatches are chemical based White Masterbatches for Raffia Tapes (woven sacks), lamination, Moulding, Blown film, plastic three layer carry bags

Usage of White Masterbatch

 
  •    RAFFIA TAPES :- A wide range of Whites 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 of white masterbatch

The main use of White masterbatches lies in tapes, which is to provide anti-fibrillation (also known as anti-splitting) properties. There are other advantages of white masterbatch 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 White Masterbatches

White 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.
  •     White masterbatches is the most effective cost-saving solution for worldwide plastic processors.
  •    CaCO3 White 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 Whites, and may be referred to as additive masterbatches.

White Masterbatch for nonwoven materials

At Shivam we offer variousl grades of White mastrebatch for non-woven fabric.

There are a number of benefits of use of Whites in non-woven fabric intended for hygiene, medical, personal care, geotextile, industrial and many other applications.

Adding White 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 White masterbatch disperses well in resins and incorporates easily during extrusion.

 
  •     White masterbatch is modifying fiber surface so that containing CaCO3 non-woven material is softer than the one with only polypropylene (PP). Micro roughness reduces surface luster giving a more matte appearance to the fabric.
  •    Calcium carbonate White masterbatch Increases surface area gives improvements in air filtration and oil absorption.
  •    White masterbatches Due to natural whiteness CaCO3 will provide good color in fabrics, with limited yellowness. Increased opacity in fibers leads to improved covering power of the web.
  •    White masterbatch Increases thermal conductivity of CaCO3 allows for faster throughput or reduced processing temperatures leading to increased productivity or energy savings.

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 White masterbatch in injection-moulded products are

 
  •    lower shrinkage
  •    better flexural stiffness,
  •    higher thermal conductivity
  •    higher impact resistance.

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 White masterbatch into PP resin.

White Masterbatch for Extrusion of Films and Sheets

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:

 
  •    Higher blocking and slip resistance.
  •    Greater tensile strength of film after stretching.
  •    Improved mated surface for printing.
  •    Food Contact Use" compliance due to absence of toxic components.
  •    Higher quality of folding and creasing.

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.

White Masterbatch for extrusion of yarn and twine

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 White masterbatch is enough to solve the problem.

Other benefits from using of white masterbatches in flat PP/PE yarn production

 
  • Improved vertical tearing resistance and tensile strength of PP flat yarn in PP woven bags.
  • Anti-slip effect and facilitating winding.
  • Greater tensile strength of the yarn after stretching.
  • Stiffed yarn makes products firmer and more stable.
  • Higher lifetime of cutting blades because the amount of abrasive titanium dioxide as well as anti-blocking and anti-slip additives can be reduced.
  • Self-cleaning of extruder and dies
  • Increased output.
