Calcium carbonate is the most commonly used filler in the plastic industry (specifically, the production of plastic additives); the purpose is to replace the final product using 100% virgin plastic. Although processing technologies have been studied and applied over the years, CaC03 is still considered the primary raw material and cannot be changed.
So why is natural calcium carbonate powder widely used in the production of Filler masterbatch?
Effect of calcium carbonate powder on the production of Filler masterbatch
• When using CaCO3 powder as a plastic additive and replacing a part of raw materials, the plastic resin manufacturer can also reduce the production cost to the maximum for customers.
• Calcium carbonate powder also has the function of helping plastic products increase hardness, durability, adhesion as well as impact resistance. The aesthetics of the final product is also significantly increased.
• CaCO3 powder also reduces the melting pressure of plastic when shaping plastic into product forms. When used in production, calcium carbonate masterbatch is a relatively good stabilizer, which can help to improve the bubbles in the resin production process. So we can allow the product to achieve a smooth and delicate surface.
• Calcium carbonate powder improves and corrects the gloss and opacity of the product surface.
• Adding calcium carbonate powder to plastic products also increases the printability on its surface.
In the manufacturing field, calcium carbonate filler is used to produce a variety of plastic granules applied to rigid, flexible thermoplastic resins. Applications created through injection molding with CaCO3 filler masterbatches include supermarket food wraps, shopping bags, garbage bags, agricultural films, etc.
CaCO3 powder is also widely used in other industries
Not only for the plastic & resin industry, but calcium carbonate powder is also widely used in many other industrial productions for the following reasons:
• This raw material is highly abundant and available in many regions around the world. Large reserves allow unrestricted extraction of the substance, resulting in low cost and stable supply in the long run.
• Calcium carbonate has a moderate hardness, not too soft but not too hard, so it’s easy to process and can be milled into powder or larger sizes.
• Finally, calcium carbonate powder has the right chemistry to combine with many other substances so that manufacturers can combine this substance with a variety of resins and polymers.
