Founded in Switzerland in 1884, OMYA is a world-leading multinational manufacturer of industrial mineral products. Its main products are calcium carbonate, functional calcium carbonate, activated calcium carbonate, lightweight hollow spheres, etc. . In 1996, Omiya came to China, and its products serve various industries such as plastics, paints, coatings, sealants and inks.
As we all know, Omiya can be called "excellent" in the calcium carbonate industry, and its technology and quality have always been recognized by the industry in terms of calcium carbonate manufacturing and application.
1In recent years, Omya has published patent technology analysis
Omiya announced 32 invention patents related to calcium carbonate from 2016 to 2021
Omiya's patent distribution of calcium carbonate in different fields from 2016 to 2021
In addition, in terms of product functionalization, there are 1 item each of anti-caking agent, plastic film pore-forming agent, and odor adsorbent. In other aspects, 1 item of filler flotation, 1 item of method to improve particle size distribution, 3 items of suspended filler system, 1 item of flocculation filler system, and 1 item of flotation equipment.
According to the above distribution and changes in the application fields of calcium carbonate, coatings, medicines, catalysts, fiber materials, plastics, general products and other fields, as well as functional products and new filler systems are more important. However, the editor of Powder Network found in various patent technical abstracts that particle size distribution, surface modification, high dispersion, porous and irregular morphology, compounding, inorganic/organic blending, etc. have repeatedly become the "core" of invention patents. . We can understand that a company has ended the mission of calcium carbonate as a "common filler".
2 Omiya "new products" have come
After reviewing the patented technologies published in recent years, the editor of Powder Network made a new discovery on Omya's official website. A "Omyanutra300" was launched, occupying a large page.

What is Omyanutra300? Actually, it is, a nutritional excipient. It is essentially a porous compressible carrier composed of calcium carbonate and tribasic calcium phosphate. Due to the high amount of active ingredients in nutraceuticals, these actives are often difficult to tighten, making tableting a challenge. In addition, formulators must select appropriate tablet processing aids - excipients - to optimize formulation compressibility and disintegration time. Performance-wise, liquids such as natural oils or herbal extracts can be converted into directly compressible powders by impregnating up to 40% crystalline actives and 60% liquids.
Why calcium carbonate? Omyanutra 300DC has superior compaction performance compared to benchmarks such as lactose and microcrystalline cellulose (MCC). In addition, the minerals provide rapid disintegration due to the porous structure of the particles, and this porosity also enables easy entrainment and release of active ingredients.
Whether it is Omya's published patents or new excipients, the value of calcium carbonate products has been greatly explored. Some people think that domestic calcium carbonate is leading in technology, equipment, scientific research environment and development history. That's all true, but at least it's not comprehensive. At present, the domestic market has been advocating the functional and high-value application of calcium carbonate products, but the use of fillers is still the main direction of calcium carbonate application. The number of domestic enterprises that can produce "fine", "new" and "special" calcium acid calcium products has gradually increased, but the number of shallow processing enterprises is still large, and they also occupy most of the resources. There are many enterprises that "do not plan" to innovate their products, and their sense of responsibility is not strong. "Weak" key.
write at the end
The editor of Powder Network believes that everyone can see that the era of calcium carbonate as a functional product has come a long time ago, but some people also pray that the era of calcium carbonate as a filler will not end. Of course, we hope and expect that there will be more powerful enterprises that will develop high-quality and distinctive calcium carbonate products from the starting point of taking on social responsibilities. It can be said that it is for the sake of the future of our company and the future of our industry.
