October 23, 2024 – Japanese Nano-Calcium Carbonate Industry Demonstrates Robust Strength, with Multiple Companies Leading the Global Market
Japanese companies such as Shiroishi Kogyo Co., Ltd., Maruo Calcium, and Takehara Chemical have established a prominent presence in the nano-calcium carbonate sector, thanks to their advanced technologies and extensive experience. Shiroishi Kogyo, a pioneer in the industry with a history spanning over a century, boasts a total production capacity of 250,000 tons across its factories in Japan and Austria. Its products find widespread application across various industries.

In the rubber and plastic industries, nano-calcium carbonate stands out for its unique properties that enhance product quality. It not only improves the processability, softness, and smoothness of rubber and plastic products but also significantly boosts the strength, rigidity, and durability of items like tires and automotive parts. Furthermore, in the coatings and inks sector, the addition of nano-calcium carbonate results in clearer and more durable paint films, as well as more elegant and uniform ink printing, while reducing costs.
According to AsiaMB’s sources, nano-calcium carbonate also exhibits exceptional performance in sealants and adhesives. Its excellent particle size stability and uniform dispersion provide sealants with outstanding elasticity, waterproofing, air tightness, and rheological properties. Shiroishi Kogyo’s main products sold in the Chinese market, such as Hakugen CCR and CC, cater to diverse customer needs.
The paper industry shows a strong demand for nano-calcium carbonate, as it significantly enhances paper’s brightness, opacity, gloss, and ink absorbency while reducing costs. Compared to domestic products, Japanese manufacturers’ nano-calcium carbonate is subject to stricter control over crystal shape and particle size distribution, resulting in lower oil absorption and a focus on customer usage effectiveness.
Moreover, nano-calcium carbonate offers broad application prospects in the food, ceramics, and engineering plastics sectors. In the food industry, it can increase the calcium content of dairy beverages and inhibit sedimentation, while also improving the texture and taste of seafood sauces. In ceramics, uniformly distributed cubic calcium carbonate particles are used to produce low-temperature densified ceramics. In engineering plastics, nano-calcium carbonate prepared through a new double-layer modification technique enables the production of highly white and heat-resistant finished products.
Notably, Japanese companies have also developed new products such as lightweight fillers and high-purity calcium carbonate. Lightweight fillers, characterized by their low specific gravity and resistance to fragmentation, are suitable for applications in rubber and plastics. High-purity calcium carbonate, mainly used in life sciences, electronics, and optics, boasts high added value.
Domestic manufacturers can draw inspiration from Japanese companies’ experience and technology, either by independently developing or introducing relevant technologies. This will help expand the application scope of calcium carbonate, enhance product added value, and secure a more favorable position in the global market.
