Filler masterbatch is widely applied in many aspects in the plastic industry. So what exactly is filler masterbatch and how is it applied into plastic manufacture? Let’s discover in the article below!
Filler masterbatch is the combination of CaCO3, primary plastic resin and other special additives in accordance with customer’s demand. The production of filler masterbatch includes 4 steps:
First of all, primary plastic is made up of high molecular polymers, which are constituted of monomers. To create primary plastic, humans combine natural components including cellulose, rubber,… or Ethin, Benzol, Ethene gas, and most importantly – kerosene together. Thus, using 100% primary plastic in plastic manufacture has the following disadvantages:
Firstly, primary plastic is non eco-friendly. It takes hundreds of years for products made of primary plastic to be completely decomposed under natural conditions.
Secondly, kerosene – the main component of primary plastic largely depends on foreign suppliers, which ends up with a relatively high price of finished products. Besides, due to the instability of kerosene supply, primary plastic is easily influenced by negative effects of foreign market.
Thirdly, kerosene is a non-renewable resource, thus contributing to the unsustainable and unstable development of firms which takes kerosene as the main input material.
With a view to providing customers with an appropriate solution to address the root of the production expense problem, filler masterbatch was born.
So, how exactly plastic firms benefit from filler masterbatch?
Thanks to its outstanding advantages regarding functionality and price, filler masterbatch has been widely applied into many industries.
Injection molding is a common technology based on two main phases: extruding melted plastic mixture and pressing it into the mold for forming. This method is used to create many plastic products including rice cooker lid, toilet lid, buckets, baskets, boxes, toothbrush, plastic toys,…
The injection molding products have these following advantages:

One of the most popular plastic manufacturing methods is extrusion. After being mixed together, input materials go into the extruder through the hopper. This combination is then melted under extremely high temperature and extruded by a mould clamping cylinder in the form of fibers. The cross section of these depends on the form of the mould clamping cylinder (commonly square or round). The plastic fibers are then cooled by water or fan on the assembly line and cut into small pieces for packaging.
Extrusion is a common method to produce plastic products such as PVC pipes, straws, gutters,… thanks to its simple technology. The application of filler masterbatch into extrusion helps:
Blown molding is a common plastic manufacturing technology, especially in producing packaging (thin-film packaging, biodegradable packaging, paper packaging, packaging roll film, waste packaging,…). To create packaging film, materials mixture enters the extruder through the hopper. After being melted, it goes through an annular slit die and is formed as a thin tube. The tube is then cooled by the air ring and continues moving upwards until it passes through nip rolls, where it is flattened. This lay-flat tube is then taken back down via more rollers. The edges of the lay-flat are slit off to produce two flat film sheets and wound up onto reels.
Filler masterbatch is used in blow molding to improve the rigidity, control heat, enhance the turbidity and most importantly, cut production expense.
Thanks to its advantages, this component has been widely applied in many fields with a view to optimizing production cost and to enhancing product’s competitiveness as well. Our most popular products including:
