Our Calcium Carbonate (CaCO3) Powder has been exported to many countries such as Japan, Korea, India, Bangladesh, UAE, Pakistan, Saudi Arabia, Nepal, Sri Lanka, Indonesia, Philippines… Our products are available in various particle sizes and can be used for different industries:
- Plastic: cable, pipe, master batch, film, sheet…
- Paint & coating: interior, exterior emulsion paint…
- Paper, water treatment, environment
- Construction: Tiles, Asphalt, Ceramic, Concrete
- Food & pharma…




The company’s CACO3 products are made by fully automatic production lines under the most current modern technology with a closed ball-mill grinding system and an advanced classifier which can easily modify the particle size of products. The control system is fully computerised by dedicated software makes particle size stable.
The material source is pure white stone directly exploited from our company’s quarry. Limestone is carefully selected right inside the quarry during initial exploitation process and is brought to plant’s ground. After that, it will be cleaned by vibrating sieve system and automatic washing system before sending to jaw crusher for grinding.
