Vietnam CaCO3 Calcium Carbonate Powder: A Global Industrial Essential

Vietnam CaCO3 Calcium Carbonate Powder is more than just a local resource. It has become a vital industrial material globally. Thanks to its exceptional purity, brilliant whiteness, and cost-effectiveness, it is widely used in plastics, paper, paints, and coatings. Manufacturers turn to this versatile filler not only to enhance product performance but also to reduce raw material costs.

What Makes Vietnam CaCO3 Unique in the Global Market?

This powder is made from natural limestone found in Yên Bái and Nghệ An, two regions well known for having some of the world’s purest limestone. As a result, the CaCO3 content above 98%, very low impurities, and bright white color, it meets even the most demanding production standards. Moreover, its consistent performance makes it a preferred material for high-quality outputs.

Key Specifications: 

Property	Value
CaCO₃ Content	>98%
Whiteness	>98%
Particle Size (D97)	5–20 microns
Forms Available	Coated / Uncoated
Certifications	ISO, SGS, RoHS, REACH

Global Positioning: Why Vietnam’s CaCO3 Stands Out

Vietnam’s CaCO3 competes globally thanks to its low heavy metal content (<0.01%), which is significantly safer than some other sources where levels exceed 0.05%. Its superior whiteness and uniform particle shape lead to better dispersion in polymer matrices, improving surface finish and processing stability.

According to OEC.world (2023), Vietnam ranked among the top 3 exporters of CaCO3 globally, with an export value of over $102 million. Shipment data from Volza (Oct 2022 to Sep 2024) reports more than 131,000 shipments of CaCO3, with India, China, and Indonesia being key markets. This reflects the growing global reliance on Vietnam’s high-quality mineral fillers.

Technical Performance: Coated vs. Uncoated

Vietnam CaCO3 is available in both coated and uncoated forms:

• Coated CaCO3 is treated with stearic acid, enhancing compatibility with polymers such as PE and PP. It improves melt flow, reduces processing temperatures, and ensures smoother dispersion.
• Uncoated CaCO3 is ideal for water-based applications such as paper manufacturing or paint formulations.

These characteristics allow manufacturers to tailor their choice based on performance and production needs.

Why Choose Vietnam CaCO₃ Calcium Carbonate Powder? 

Beyond its quality, Vietnam CaCO3 stands out for consistency. For example, companies in Turkey, India, and across Europe are switching to Vietnamese sources—and with good reason. In 2023, a Turkish packaging company reduced production costs by 15% after replacing local CaCO₃ with Vietnam’s. Likewise, in 2024, a European paint manufacturer reported improved opacity and saved 12% on raw materials.

Top Benefits of Using Vietnam CaCO3 in Manufacturing

Thanks to its fine particle size (D97: 5–20 microns) and brilliant whiteness, Vietnam CaCO₃ ensures excellent dispersion and visual improvement. Consequently, manufacturers experience smoother surfaces in film and paper, brighter paint finishes, and reduced use of expensive materials like resin and titanium dioxide.

Main advantages of Vietnam CaCO₃:

• 98% CaCO₃ purity for consistent results
• High brightness (≥ 98%) and low moisture content
• Excellent compatibility with polymers and coatings
• Cost-effective substitute for resin and TiO₂
• Faster dispersion during production

Applications Of Vietnam CaCO3 Calcium Carbonate Powder

Vietnam CaCO₃ is widely used across key industries because of its flexibility and performance. Not only does it improve product quality, but it also offers significant cost advantages.

Common applications include:

• Plastics: Enhances strength and reduces polymer usage in film blowing, injection molding, and extrusion.
  
• Paper: Increases brightness and smoothness for high-grade printing and writing paper.
• Paint & Coating: Improves opacity and lowers titanium dioxide consumption.
