Calcium Filler Masterbatch

Masterbatch is a solid additive that is encapsulated in a carrier resin through a heat process, then cooled and cut into granular shapes. It is a mixture of polymer and calcium carbonate that is widely used in plastic-based product manufacturing. It has a good percentage of calcium carbonate powder (82%) combined with the resin (18%) and appropriate additives.

The addition of calcium carbonate in plastics can improve processing, performance, sustainability, and the finish impact of the final product. The use of calcium carbonate as a filler is 100% FDA approved, making it versatile in applications, including critical ones like food and medical packaging. Filler Masterbatches are cost-effective, save production costs, and enhance multiple properties of the final products.

Masterbatch is used as a filler in the manufacturing of products like Blown HDPE Film, Raffia tapes, Tarpaulins, High-density and Low-density PP/PE fabric, LDPE, LLDPE, and HDPE films, and plastic furniture.

Adding calcium carbonate filler helps improve product surfaces by:

•  Reducing luster, making the surface more matte and opaquer
•  Giving natural white color with limited yellowness
•  Creating more micro areas for air filtration and oil absorption
•  Increasing thermal conductivity and physical strength
•  Reducing processing temperature, hence the manufacturers can achieve higher productivity as well as save energy and producing costs in general.
•  Easily cooperated with multiple base resins (thanks to good dispersion ability) and processed by various methods
