In the industrial materials sector, limestone powder (CaCO3) is considered an indispensable functional filler in many manufacturing industries such as plastics, paints, paper, rubber, and construction materials. So, how much does limestone powder cost per kilogram? The price of CaCO3 depends on a number of technical factors such as particle fineness, whiteness, mineral purity, and surface treatment process – parameters that directly determine the performance and quality of the final product.

What is limestone powder?

Limestone powder is a mineral extracted from natural limestone quarries, primarily containing calcium carbonate (CaCO3). It is a fine, white granular material with good dispersion properties in various materials. It is an indispensable raw material in industry.

CaCO3 is used as a filler to improve mechanical properties.

VNAPEX specializes in providing specialized limestone powders, differing in surface treatment technology and particle size:

GCC (Ground Calcium Carbonate): Mechanically ground limestone powder.
PCC (Precipitated Calcium Carbonate): Precipitated limestone powder, with higher whiteness and purity.
Nano Canxi Cacbonat (CaCO3 Nano):Ultrafine particle size (nanometers), used in high-performance engineering plastics.
Activated Calcium Carbonate: Limestone powder is surface-coated (e.g., with stearic acid) to improve dispersion in hydrophobic polymer systems.

Factors affecting the price of limestone powder

So, how much does limestone powder cost per kilogram, and what factors affect its price on the market today?
Each technical specification of the product, such as fineness, whiteness, CaCO3 content, or activated coating technology, directly impacts the commercial value and application scope of limestone powder in various industries.

Smoothness

Fineness is a crucial factor determining the price of limestone powder. The finer the limestone powder, the more complex the production process, requiring advanced grinding and sorting technology, resulting in a higher cost.

Bột đá siêu mịn (Ultrafine): Typically has a size of D97 under 5 microns, is more expensive than coarse limestone powder, and is used in industries requiring high precision such as paint manufacturing, plastic masterbatch, and paper.
Bột đá Nano: Due to the technological requirements for producing PCC and controlling particle size at the nanometer level, nano-sized CaCO3 has the highest cost. It is used in high-end engineering materials, where it improves impact strength and optical properties without reducing transparency.

Whiteness

The degree of whiteness is one of the factors that directly affects the value of limestone powder. Products with high whiteness are often preferred in industries requiring high aesthetics and reflectivity, such as paints, plastics, or coated paper. Limestone powder with medium or lower whiteness is usually used for engineering or construction applications.

Products with high whiteness are preferred in industries requiring high aesthetic standards.

CaCO3 content

How much does limestone powder cost per kilogram? How does the CaCO3 content affect the price? The CaCO3 content in the raw material reflects the purity of the limestone powder. Products with a CaCO₃ content above 97% usually have a higher price, as they meet stringent requirements for purity, dispersion, and chemical stability.

Surface treatment technology (Activated coating)

The price of granulated (coated) limestone powder is significantly higher than that of uncoated powder. Activated limestone powder is treated with chemicals (such as stearic acid) to create a hydrophobic coating on the particle surface. This helps the powder particles disperse more evenly in the polymer matrix and reduces melt viscosity, ensuring consistent quality of both compound and masterbatch.

How much does limestone powder cost per kilogram?

How much does limestone powder cost per kilogram? The current price of limestone powder ranges from 350,000 to 450,000 VND/ton, depending on fineness, whiteness, CaCO₃ content, and surface treatment technology.

Pricing will be based on the technical specifications of each powder type, ensuring that the materials meet technical standards while optimizing input costs for the production process.

Applications of calcium carbonate powder (CaCO3).

Depending on the fineness, CaCO3 content, and surface treatment technology, limestone powder can be used in many different fields. Each application group requires its own technical standards, reflecting the role of CaCO3 not only as a cost-effective filler but also as a functional component that improves the mechanical, optical, and durability properties of the final product.

Plastics and Masterbatch Production

In the plastics industry, limestone powder is a primary filler used to reduce costs and improve properties.

Engineering plastics:Coated limestone powder or nano-sized CaCO3 is used to increase durability, hardness, and reduce cracking and air bubbles in injection molded products, especially in the production of pressure-resistant PVC pipes and fittings.
Masterbatch Filler(Filler Masterbatch): This is the most common application. Ultrafine limestone powder (with a content of 70-90%) is mixed with a polymer matrix (PE, PP) to create masterbatch granules, helping plastic manufacturers significantly reduce production costs by partially replacing expensive virgin plastics.

Paints, coatings, and paper industry

In the field of paints and coatings, limestone powder helps improve the coverage, pigment dispersion, and surface smoothness of the paint layer. Powders with a whiteness of over 95% and ultrafine particle size are often used to enhance color brightness, increase light reflectivity, and reduce production costs compared to using only white pigments such as TiO2.
In the paper industry, limestone pulp, especially precipitated calcium carbonate (PCC), is used as a filler and surface coating agent. PCC helps increase whiteness, smoothness, opacity, and printability, while also improving the mechanical properties of the paper.

Construction and animal husbandry

In the construction industry, coarse and fine limestone powder is used as an additive in the production of asphalt concrete, non-fired bricks, or as wall putty. It is cheaper than nano/activated forms.
In the aquaculture industry, limestone powder is commonly used to balance pH levels, control acidity in ponds, and provide calcium for farmed animals (shrimp, fish). The technical requirements are simpler compared to the plastics industry, resulting in lower prices.
