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
