Products - Coloured Masterbatches

Black Masterbatch  

The BLS DARK-BRIGHT Black Masterbatches contain highly dispersed carbon particles in resin matrix. High flow LLDPE carrier resin base specially formulated masterbatches with highly-dispersed carbon particles has been achieved to overcome the force of attraction between the carbon black particles and making the carbon particles uniformly wetted by the resin. This brings rheological improvement in masterbatches, thus easy flowability.

Exposure to ultraviolet rays from sunlight degrades polymers and thereby reducing their strength. Carbon Black is the cheapest and one of the excellent UV stabilizers. Uniform dispersion of small inorganic Carbon Black particles in organic polymer matrix is an important factor to impart effective UV stabilization. Higher the loading of Carbon Black particles, difficult to disperse in Polymer matrix.

The BLS Black Masterbatches are highly filled using special dispersing agent in place of low molecular weight waxes. The low molecular weight waxes in the black masterbatches will result in lowering of some properties like tensile strength and elongation percentage of the final product. Due to higher loading of Carbon Black, MFI of the masterbatches would be less than 1.0 gm/10 min and density should be in the range of 1.0 to 1.2 gm/cc.

Depending on product thickness and colour intensity, the concentration of masterbatch will vary. Dispersion technology, coupled with specific base raw materials allows processors to achieve the highest degree of opacity using minimum quantities of masterbatch. Our products are engineered to provide greater synergies with wide varieties of additive packages.

Product Highlights:

  • Ultra dispersion
  • Ease of processability
  • Resistant to ultra violet (UV) light
  • Durability against extreme weather conditions
  • Easy flow / Low viscosity products


In our quest to expand with new product range, we require sincere business partners. We are interested to appoint forward looking with proven track record Sales Agents across the country.
