Product Introduction
Ground calcium carbonate (GCC) is made by grinding natural carbonate minerals such as calcite, marble, and limestone. As a commonly used powdered inorganic filler, it boasts advantages including high chemical purity, strong inertness, resistance to chemical reactions, good thermal stability (no decomposition below 400℃), high whiteness, low oil absorption, low refractive index, soft texture, dryness (free of crystal water), low hardness with small abrasion value, non-toxicity, odorlessness, and excellent dispersibility. Therefore, it is widely applied in industries such as rubber, plastics, paints, water-based coatings, papermaking, concrete, and fireproof ceiling materials.
Specification

Heavy calcium carbonate, produced via physical processing, offers distinct advantages over light calcium carbonate: lower production costs, significantly reduced oil absorption, and a more pronounced boost to the surface gloss of end products. As a result, it has become the preferred filler for the vast majority of manufacturers.
Its applications span key industries including rubber, plastics, papermaking, and coatings. Beyond these, it also sees extensive use in pharmaceuticals, food processing, feed production, and toothpaste manufacturing.
Food-grade expanded perlite for industrial filtration applications. High flow rates, excellent clarity, and consistent performance as filter aid in food, beverage, and pharmaceutical industries.

Sintered colored sand, also known as high-temperature sintered colored sand or ceramic colored sand, is a high-end decorative material that uses a high-temperature ceramic sintering process to color selected quartz sand. Its core lies in using high temperatures (usually above 800℃) to fuse inorganic ceramic glazes with the surface of the quartz sand, forming a strong and dense colored ceramic layer.
With their high strength and chemical stability, solid white glass microspheres excel as precision abrasives, polymer fillers, and reflective agents across aerospace, automotive, and electronics industries.
Vibrant colored rock flakes with superior color fastness. Custom color matching available with RAL system. Excellent weather resistance for long-lasting decorative effects. Minimum order 50kg.
Nakhi Bentonite is a high-quality clay mineral with excellent adsorption and swelling properties. It’s widely used in water treatment, oil drilling, and soil improvement. Its fine particle size and high cation exchange capacity ensure strong performance in various industrial and environmental applications.
High-performance engineered glass flakes: flaky glass fillers enhancing anti-corrosion, wear resistance, and barrier properties. Typical specs: 2–10μm thickness, 100–3000μm diameter. Create a "labyrinth effect" in coatings/linings to block corrosive media and extend industrial equipment/structure lifespan.
