Bitwater (Shenzhen) Technology Co., Ltd. specializes in insulation solutions for refractory applications, offering tailored products to meet the unique demands of high-temperature environments. Focused on vermiculite-based materials, the company provides firebricks, insulation boards, and lining systems designed for aluminium smelting cells, industrial furnaces, and fireplace constructions. High-density (500 kg/m³) firebricks excel in resisting molten metal temperatures and electrolyte corrosion, while low-density (400 kg/m³) boards optimize heat retention in boilers with minimal weight. These solutions feature low thermal conductivity (0.06–0.2 W/m·K), high compressive strength (≥3.5 MPa), and dimensional stability, ensuring reliable refractory performance. With fireproof ratings and resistance to thermal cycling, they deliver sustained insulation in the most challenging refractory settings.
