About Calcium Carbonate for Sheet
Calcium Carbonate for Sheet
Shivish Microns LLP Calcium Carbonate (CaCO3) is one of the most widely used mineral fillers in the plastics industry, and its use in rigid packaging has increased significantly over the years. Once thought of simply as a resin extender, the addition of calcium carbonate in plastics has been shown to contribute to increased performance, improved processing, and improved sustainability of the finished part. Check out five great reasons why you should consider using
Shivish Microns LLP calcium carbonate filled polypropylene sheet for your next project: 1.Improved Performance: The addition of calcium carbonate to polypropylene sheet has been shown to improve the performance of the plastic across the board. At just an 18% loading, studies showed that the calcium carbonate improved several key properties. Improvements in heat deflection temperature, impact strength, stiffness, barrier properties, and print quality were all observed. In fact, even greater gains were realized at higher loading levels. Calcium carbonate is currently being used in commercial applications at up to a 40% fill rate all while improving part function. 2.Improved Processing: The use of calcium carbonate in polypropylene sheet can help streamline thermoforming applications by allowing the plastic to heat up and cool down faster. The improved thermal conductivity allows for significant energy savings through improved productivity, higher outputs, and faster conversion rates. In addition, faster cooling helps to reduce shrinkage and results in less warping, allowing for greater predictability in the finished part. 3.Economic Advantages: The resin market can be volatile, and integrating calcium carbonate can protect consumers against unpredictable price fluctuations. The displacement of resin allows for significant raw material cost savings by replacing up to 40% of plastic with price-stable calcium carbonate. In addition, the improved thermal conductivity, higher output rates and improved conversion rates result in increased operating efficiencies, all of which positively impact the bottom line. 4.Sustainability: For all of the benefits that plastics afford us in modern society, it comes at a cost and studies have shown that consumers and brand owners are becoming increasingly more concerned with the sustainability of their packaging. Studies conducted by Heritage Plastics have shown that using a 40% loaded calcium carbonate filled polypropylene can generate a Green House Gas savings of approximately 23% - and this is before taking into consideration the increased productivity mentioned. 5.FDA Approved: Calcium carbonate as a plastics additive is 100% FDA approved, allowing for versatility among applications and use in critical applications in the food packaging foodservice packaging and medical packaging markets.

FAQs of Calcium Carbonate for Sheet:
Q: How is calcium carbonate used as a filler in sheet manufacturing?
A: Calcium carbonate is incorporated into plastic, PVC, and foam sheets to improve their mechanical properties, such as strength and dimensional stability. Its fine particle size (210 microns) and high whiteness ensure a smooth, uniform surface and enhanced visual appeal.
Q: What are the primary benefits of using this calcium carbonate in sheet production?
A: This grade of calcium carbonate provides improved mechanical strength, high dimensional stability, excellent surface finish, and low thermal conductivity for better insulation. Its very low porosity enhances the uniformity of sheet surfaces.
Q: When should calcium carbonate be added during the sheet manufacturing process?
A: Calcium carbonate should be mixed with polymer resins during the compounding or blending stage, before extrusion or molding, to ensure optimal dispersion and performance in the finished sheets.
Q: Where can this calcium carbonate be applied aside from sheet manufacturing?
A: Apart from plastic and PVC sheet manufacturing, this calcium carbonate is also used in paper production, paints, coatings, and rubber industries, owing to its high purity and customizable particle size.
Q: What process ensures the stability and purity of this calcium carbonate product?
A: This product undergoes rigorous processing to maintain a minimum 98% CaCO3 content, low moisture (max 0.2%), and stable chemical reactivity. Careful packaging in HDPE bags preserves these attributes during storage and transport.
Q: How does the low thermal conductivity of this calcium carbonate benefit sheet applications?
A: The low thermal conductivity enhances the insulation properties of sheets made with this filler, making them suitable for applications requiring temperature stability and energy efficiency.
