High‑purity expanded vermiculite manufactured by Bitwat (Shenzhen) Technology Co., Ltd. is a versatile refractory solution tailored for diverse high‑temperature applications across multiple industries. Utilizing non‑asbestos processing technology, this vermiculite exhibits exceptional fire resistance, thermal insulation, and chemical stability, making it suitable for harsh operating conditions. The controlled expansion process creates a consistent pore structure, resulting in low thermal conductivity and efficient heat containment to prevent flame spread and heat transfer. In building construction, vermiculite forms a protective layer around steel frameworks, slowing heat penetration and maintaining structural integrity during fire emergencies. For heating equipment such as stoves, fireplaces, and gas boilers, vermiculite offers durable insulation that enhances operational safety, improves energy efficiency, and extends service life. In metallurgical facilities, vermiculite is an essential component of insulation systems for steel ladles and tundishes, maintaining stable temperatures for molten metal handling and maximizing energy utilization. Resistant to oxidation and chemical corrosion, vermiculite retains its structural integrity in demanding environments, ensuring long‑lasting performance and reliability. Its eco‑friendly composition supports sustainable industrial practices while meeting strict international quality and safety standards.
