In many industries, The most suitable grade of calcium carbonate blended with specialty additives is used to form many product ranges of masterbatches. To avoid the impact of coal or oil prices on the production of plastics, many manufacturers use calcium carbonate. They usually mix this powder in primary plastic while making filler masterbatch or compound. The purpose of this action is to make the final products replace using 100% primary plastic.

Calcium Carbonate has been the most commonly used filler in the plastic industry and their position has never declined during the years despite the processing and modifying technologies that have been researched and applied more and years. Not only in the plastics industry, but calcium carbonate filler also functions as filler that is widely utilized in other industries and production worldwide. the reason CaCO3 is favored because

• Firstly, this material source is extremely abundant and available in many areas and regions around the world. The abundance of reserves allows the exploitation of this substance to be unrestricted, leading to low cost and stable supply for a long time.
• Secondly, calcium carbonate has moderate hardness, isn't too soft but still not too hard, making it easy to process and the process can grind into powder or larger sizes.
• Thirdly, CaCO3 also works in reducing plastic melting pressure when shaping plastic into product forms. When utilized in production, calcium carbonate masterbatch is a relatively good stabilizer, which can help improve bubble floatation within the production of plastic beads. This helps the product achieve a smooth and exquisite surface.
• Finally, Calcium carbonate powder is chemically suitable for combination with many other substances, so manufacturers can combine this substance with many different forms of plastics and polymers.

Effect of calcium carbonate filler on the Plastic Industry

• When used as a plastic additive, in addition to replacing a part of raw materials, and helps manufacturers to reduce production costs as much as possible.
• Calcium carbonate powder also functions helping plastic products increase hardness, durability, adhesion as well as impact resistance. The aesthetics of the final product also increased significantly
• Thirdly, CaCO3 also works in reducing plastic melting pressure when shaping plastic into product forms. When utilized in production, calcium carbonate masterbatch is a relatively good stabilizer, which can help improve bubble floatation within the production of plastic beads. This helps the product achieve a smooth and exquisite surface.
• Calcium carbonate improves and adjusts the glossiness and opacity of the product’s surface.
• Adding Calcium carbonate powder to plastic products also increases its surface printability.

In the production field, calcium carbonate filler is used in combination with a wide variety of plastics, from rigid plastic, flexible plastic to thermoplastic. Applications of calcium carbonate masterbatch are numerous. Applications generated through the injection molding methods with this type of masterbatch includes food wraps used in supermarkets, shopping bags, garbage bags, agricultural films, etc. Thus, calcium carbonate filler brings a lot of economic value to producers, both in quantity, production capacity, and product quality.
