Product Usage
Oil drilling, packing materials, radiation shielding materials, etc.
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.
Extra thin composite flakes with 0.2mm thickness for ultra-premium coating finishes. Lightweight formulation reduces coating weight by 25% while maintaining superior stone simulation effect. Ideal for delicate surfaces and detailed applications.
Horticultural expanded perlite for professional gardening and agriculture. Improves soil aeration, drainage, and moisture retention. Sterile, pH neutral, and ideal for soilless growing mixes.
Raw vermiculite is a natural, layered silicate mineral, typically appearing as brownish or golden flakes. It’s lightweight, absorbent, and heat-resistant, widely used in horticulture (soil amendment), construction (insulation), and packaging (cushioning), with good expandability when heated.
Rather than elaborate artificial carving, pebbles preserve the marks formed by time and natural forces to the greatest degree. Available in various colors and complete sizes, they’re extensively applied in landscape and construction sectors due to their natural properties, water permeability, wear resistance and abundant natural appeal—such as paving, garden paths, water feature design, cultural stone, stone cladding and filter media.
Titanium dioxide is a high-performance white pigment with excellent opacity, brightness, and UV resistance. It’s widely used in paints, plastics, and coatings for vivid, durable finishes.
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.
Glass flakes are high-performance flaky glass fillers designed to boost anti-corrosion, wear resistance and barrier capabilities. Featuring a typical thickness of 2–10μm and diameter of 100–3000μm, they form a "labyrinth effect" in coatings/linings, which effectively stops corrosive media from penetrating and prolongs the service life of industrial equipment and structures.
