Defining Filler Masterbatch

Filler masterbatch, also known as calcium carbonate filler, ranks among the most prevalent plastic additives. It is composed of CaCO3, primary plastic resin, and specific additives tailored to customer requirements. The manufacturing of filler masterbatch involves four key steps: Step 1: A high-speed mixer combines CaCO3, additives, and plastic resin. Step 2: The resulting mixture is melted at high temperatures. Step 3: This molten mixture is then cooled and fed into a screw extruder, where it is pushed forward and molded. Step 4: The extruder’s output is cut into small, similar pieces, which are then employed in plastic production as filler masterbatch.

  1. First and foremost, primary plastic is crafted from high molecular polymers, comprising monomers and a blend of natural elements like cellulose, rubber, or ethylene, benzene, and ethene gases, with kerosene playing a crucial role. Consequently, employing 100% primary plastic in manufacturing has the following drawbacks:

  • Primary plastic is non-environmentally friendly and requires centuries to fully decompose naturally.
  • Heavy reliance on foreign kerosene suppliers results in higher product costs and vulnerability to international market fluctuations.
  • Kerosene, a non-renewable resource, contributes to the unsustainable and precarious development of businesses relying on it as their primary input material.
  1. So, how does filler masterbatch benefit plastic manufacturers?
  • Cost Reduction: Filler masterbatch contains CaCO3, a globally renowned, high-quality resource. This lowers production costs, stabilizes input material quantities, and enhances product competitiveness.
  • Improved Physical Properties: Filler masterbatch boosts rigidity, plasticity, and reduces shrinkage.
  • Versatile Applications: Thanks to its suitable toughness and stable chemical attributes, filler masterbatch can be easily cut into small pieces, crushed into powder, or blended with other plastic resins to create more functional products.
  • Enhanced Forming: Filler masterbatch facilitates proper heat distribution in processes like blow film and raffia, eliminating surface imperfections in plastic products.
  1. Due to its outstanding functional and cost advantages, filler masterbatch has found extensive application in numerous industries.

Injection Molding: This widely used technology involves extruding molten plastic mixtures and molding them. It is employed to manufacture diverse plastic products, such as rice cooker lids, toilet lids, buckets, baskets, boxes, toothbrushes, and plastic toys. When filler masterbatch is utilized, the advantages include:

  • Reduced manufacturing lead times due to CaCO3’s excellent thermal conductivity.
  • Lower input material costs, as CaCO3 is significantly more cost-effective than primary plastic.
  • Energy savings from decreased production times.
  • Enhanced stability during the product forming process.
  • Reduced carbon footprint through the replacement of primary plastic with CaCO3.
  • Improved physical properties (flexibility, rigidity, etc.).
  • Enhanced tear resistance, regardless of product thickness.
  • Enhanced printability of products.

Extrusion: Extrusion, a prevalent plastic manufacturing method, involves combining input materials, melting them at high temperatures, and shaping them into fibers through a molding cylinder. The choice to include filler masterbatch helps:

  • Decrease production costs, thanks to the cost-effectiveness of CaCO3 compared to primary plastic, which subsequently leads to more competitive product pricing.

Blown Film: Blown film technology, frequently used for producing various types of packaging, utilizes filler masterbatch to enhance rigidity, control heat, improve turbidity, and ultimately reduce production expenses.

  1. Owing to its compelling benefits, filler masterbatch has seen widespread adoption across various industries, leading to enhanced cost-efficiency and product competitiveness.
