Product details
1）Tyre: light calcium carbonate and nano calcium carbonate are often used to partially replace low-structure carbon black and silica in the outer rubber (more than 70%) and inner rubber of power car tyres, and in the car tyre carcass cord fabric rubber, airtight ply rubber, inner liner rubber and inner tube rubber to reduce the production cost.
In addition, nano-calcium carbonate and ultra-fine active zinc oxide and replace ordinary zinc oxide can improve the tensile strength, elongation, flexural properties and fatigue resistance of car tyre tread rubber.
(2) Hose and tape: light calcium carbonate and nano-calcium carbonate for hose and tape, one is to play the role of white reinforcing filler, and the second is to improve the dispersion of the rubber. Calcium carbonate in the hose can be used for ordinary hoses, coloured hoses, hydraulic hoses and short-fibre reinforced hoses, etc., in the tape can be used for conveyor belts, transmission belts and timing belts.
(3) rubber shoes: calcium carbonate can adapt to different colour requirements, can improve the rubber mixing and extrusion performance, in the rubber shoes are widely used, often with carbon black, silica, titanium dioxide and clay and used in rubber shoes, uppers, soles and heels and other parts.
(4) wire and cable: calcium carbonate is generally used with carbon black, silica, clay and talc, etc. and used as mining wire and cable, marine wire and cable, high-voltage wire and cable sheathing and electrical wire and cable rubber reinforcement filler.
In the chlorinated rubber, such as CR, chlorinated polyethylene rubber (CM) and chlorinated cis-butadiene rubber as the main material of the wire and cable rubber, calcium carbonate in addition to the role of reinforcing filler, but also to reduce the acidity of the rubber and absorb hydrogen chloride produced during the processing of rubber, thus avoiding the rubber to appear delayed vulcanisation and the role of the phenomenon of the return to the original, and at the same time, to improve the performance of the rubber extrusion.
Key Application Segments Driving Demand
Paper Industry: This remains the single largest application segment, accounting for 34.6% of the market's overall value in 2024 (revenues of $4.13 billion). PCC, in particular, is valued as a cost-effective mineral that enhances paper quality and can serve as an alternative to wood pulp.
Industrial Fillers: This is the dominant application category by revenue share. GCC's properties—special whiteness, light scattering, brightness, and low cost compared to alternatives like wood flour—make it indispensable in plastics, paints, coatings, adhesives, and sealants. The demand is closely tied to construction activity and infrastructure upgrades across the region.
Emerging and Growth Applications:
Rubber Industry: Nano calcium carbonate is gaining traction as a superior and cost-effective substitute for carbon black.
Construction: A critical driver for demand in paints, concrete, asphalt, and plasters. The modest recovery in Eurozone construction activity in early 2025 provided underlying support for consumption.
Diversifying Uses: Applications are expanding into animal feed, food and pharmaceuticals, water treatment, and agriculture

Product method of Bulk Calcium carbonate.
Crushing method will be white stone (natural limestone) first in the jaw crusher coarse crushing, so that the block size of 40 - 60mm, and then lifting machine to Raymond crusher for crushing. The blower will blow the crushed semi-finished products to the cyclone classifier for grading. Coarse products return to the crusher for reprocessing. Qualified products are separated by cyclone separator to get products.
Frequently Asked Questions
Q1: What is the difference between calcium carbonate powder and calcium citrate?
A: Calcium carbonate has a higher calcium content (40% vs 21%) and requires stomach acid for absorption, so it's best taken with meals. Calcium citrate is absorbed well even without meals and is suitable for people with low stomach acid secretion. Calcium carbonate is generally more economical.
Q2: Will calcium carbonate powder cause constipation?
A: Some people may experience mild constipation. This can be alleviated by ensuring adequate water intake, increasing dietary fiber intake, and considering taking smaller doses in divided doses.
Q3: How to determine the quality of calcium carbonate powder?
A: Look for products with USP certification, third-party heavy metal testing reports, and clear labeling as "food grade." High-quality powder should be pure white, fine, and free of impurities.
Q4: Can calcium carbonate powder be heated?
A: Yes, calcium carbonate is heat-stable and suitable for baking applications. However, extremely high temperatures (above 825°C) will cause it to decompose.
Q5: Can children use calcium carbonate powder?
A: Under the guidance of a doctor or nutritionist, it can be used in appropriate amounts. Children's calcium needs vary, and the dosage needs to be adjusted carefully. It is not recommended to supplement children without professional guidance.
Q6: What are the interactions between calcium carbonate powder and medications?
A: Calcium may interfere with the absorption of some medications, such as thyroid medications, bisphosphonates, certain antibiotics, and iron supplements. When taking these medications, calcium supplements should be taken 2-4 hours apart.
