Product Introduction

Perlite cenospheres, also known as vitrified microspheres or new-generation cenospheres, are primarily composed of silica (SiO2) and alumina (Al2O3). These hollow spheres feature thin walls, smooth and sealed surfaces, and excellent floatability, with a floatation rate exceeding 85%. Thanks to their low density and small particle size, they float on water and provide characteristics such as high strength, low thermal conductivity, fire resistance (up to 1580°C), and superior insulation properties. These attributes make them ideal for use in oilfield drilling, well cementing, refractory materials, and thermal insulation.

Product Features

• High Floatation Rate: Cenospheres have a floatation rate exceeding 85%, making them lightweight and easy to handle.
• Low Density: Bulk density ranges from 240 to 300 kg/m³, making them an effective solution for reducing the weight of drilling mud and cement.
• Thermal Resistance: They can withstand temperatures up to 1580°C, making them suitable for high-temperature environments.
• Chemical Stability: High silica and alumina content gives these cenospheres excellent chemical resistance.
• Cost Efficiency: More affordable than traditional fly ash cenospheres, offering cost-effective optimization for oilfield operations.
