In recent periods, foreign trade inquiries for domestically produced Calcium Carbonate (CAS#471-34-1) have maintained an upward trend. Export orders for high-quality ground calcium carbonate and precipitated calcium carbonate keep expanding steadily. Southeast Asia, the Middle East, Europe, Latin America and Africa are core consumption markets. Sustained purchasing demands come from coating manufacturers, plastic masterbatch factories, paper mills, rubber compounding plants, adhesive producers, construction material enterprises and food & pharmaceutical additive workshops. Driven by the recovery of global downstream manufacturing, many end-users increase regular stock replenishment. Most overseas buyers pay close attention to whiteness, particle size distribution, calcium content, moisture, oil absorption value, heavy metal index and complete documents including COA, MSDS and food grade certificates when placing bulk orders. Many buyers place small trial shipments first to test dispersibility, stability and batch consistency before signing long-term framework contracts and repeating large orders.
Calcium Carbonate is an odorless white fine powder, insoluble in water, slightly soluble in ammonium salt solution. It can be divided into ground calcium carbonate (GCC) and precipitated calcium carbonate (PCC) according to production processes. As a versatile inorganic filler and functional additive, it features low cost, high whiteness, stable chemical property and good dispersibility after surface treatment. It is widely used as filling and whitening raw material in multiple industries. Its major applications cover architectural & industrial coatings, plastic profiles, films and injection molding products, paper filling and coating, rubber goods, sealants, putty and building dry mortar. Food grade Calcium Carbonate serves as calcium fortifier, anti-caking agent and processing aid in food industry. Pharmaceutical grade grades are used as tablet excipients and calcium supplement raw materials. It also applies in toothpaste, cosmetics, water treatment and environmental protection fields.
Our supplied calcium carbonate products are produced under standardized production procedures, with controllable particle size and stable quality. Surface modification service is available to improve compatibility with polymer substrates. With the continuous recovery of global manufacturing and packaging, construction and new material sectors, the overseas market demand for Calcium Carbonate is expected to stay robust in the next stage.
