Premium Ceramic Proppant Supplier

Quartz Sand: Processed from natural quartz grains, it offers small density, large porosity, excellent water and air permeability, environmental friendliness, and resistance to decomposition. It's cost-effective and suitable for general applications.

Perlite: A natural volcanic rock rich in trace elements, organic matter, and phosphate. It promotes plant growth, nutrient absorption, and has excellent water retention, ventilation, and fertilizer retention properties.

Coated ceramic sand undergoes surface treatment with a protective film that enhances durability, wear resistance, and compressive strength. This allows it to perform under higher pressure and temperature conditions compared to ordinary ceramic fracturing sand.

The coating increases surface hardness and reduces interaction with fracturing fluids, improving long-term conductivity and stability in deep wells.

The choice depends on specific application requirements and site conditions. Ordinary ceramsite is widely used due to its high strength, low density, wear resistance, and chemical stability—ideal for most fracturing operations.

Coated ceramsite is preferred in high-pressure, high-temperature environments where enhanced performance and reduced fluid interaction are critical. The coating reduces contact area with fracturing fluid, improving efficiency and longevity.
