What is Filler Masterbatch?
Masterbatch filler, sometimes called calcium carbonate filler, is a popular choice for many plastics. The exact proportions of CaCO3, the main plastic resin, and any other additives requested by the client are all carefully considered.
There are four stages to making filler masterbatches:
- A high-speed mixer is used to combine the CaCO3, additives, and plastic resin in the first step.
- Melt the aforementioned combination thoroughly over high heat.
- After the mixture has cooled, it is loaded into a screw extruder, advanced, and pressed into the mold.
- The extruder’s output is then chopped into uniformly sized pieces. They are a type of filler masterbatch used in the production of plastics.
How is Filler Masterbatch applied in the plastic industry?
Many sectors have begun using filler masterbatch because of its great price-to-function ratio.
Injection Molding
The two primary steps of the widely used method known as injection molding are pushing the molten plastic mixture into the mold and then extruding it. Countless plastic items, such as lids for rice cookers and toilets, as well as buckets, baskets, boxes, toothbrushes, toys, and more, are made using this technique.
The injection-molded goods benefit from filler masterbatch in the following ways:
- Reduced production time because of CaCO3’s high heat conductivity.
- Due to CaCO3’s reasonable price, which is much cheaper than main plastic, input material expenses are reduced.
- Saved energy as a result of shorter production times.
- As the product is being formed, its stability is enhanced.
- The substitution of CaCO3 for basic plastic results in a smaller carbon footprint.
- An improvement in the product’s mechanical characteristics (hardness, pliability, etc.)
- The tear resistance of a product is proportional to its thickness.
- The printability of the product is enhanced.
Extrusion
In the plastics industry, extrusion is a common and widely used process. The hopper is where the combined ingredients go into the extruder. A mold-clamping cylinder extrudes the mixture as fibers after it has melted at extremely high temperatures. These often have a square or circular cross section, depending on the shape of the cylinder used to clamp the mold.
- On the production line, the plastic fibers are sliced into little pieces and chilled with water or a fan before packaging.
- The easy technique of extrusion makes it a widespread method for producing plastic goods like PVC pipes, straws, gutters, etc.
When filler masterbatch is used in extrusion, it aids:
- Production costs can be reduced because CaCO3 is more affordable than primary plastic. This, in turn, lowers the product price and increases competitiveness.
- Improving the product’s stiffness and durability, as well as its resistance to bending and twisting.
Blown film
Packaging (thin film, biodegradable paper, packaging roll film, trash, etc.) is a frequent application of blown film, a plastic production technique. The hopper is the entry point for the material mixture into the extruder, which is used to make packaging film. The material is shaped into a narrow tube after it has been melted by passing it through an annular slit die. After cooling in the air ring, the tube continues its ascent and eventually flattens out as it goes through nip rolls. After that, additional rollers lower this lay-flat tube back down. The lay-flat is cut into two flat film sheets by slitting its edges and then wound onto reels.
How does your production utilize filler masterbatch?
- One typical way to make plastic films is using blow molding technology.
- Blown film uses filler masterbatch to control heat, increase turbidity, and, most critically, reduce production costs while improving stiffness.
