Vermiculite based refractory products by Bitwat (Shenzhen) Technology Co., Ltd. represent a premium category of insulation materials designed for optimal fire protection and thermal management. Produced from carefully selected expanded silver vermiculite and inorganic binders, these products undergo high‑temperature sintering to create a stable, porous structure that delivers consistent performance under extreme heat stress. With excellent fire‑rating properties and low heat transfer rates, vermiculite effectively prevents flame propagation and temperature escalation in high‑risk environments. In building construction, vermiculite boards and bricks are widely used to protect steel structures, ensuring compliance with fire safety regulations and enhancing overall building resilience. For heating appliance manufacturers, vermiculite provides reliable insulation solutions that improve heat efficiency, enhance user safety, and extend product lifespans. In the metallurgical sector, vermiculite panels are employed as insulation layers in steel ladles and tundishes, minimizing heat loss and supporting precise temperature control during metal processing. Lightweight and easy to handle, vermiculite products reduce installation complexity while their machinable nature allows adaptation to custom design specifications. Environmentally responsible and long‑lasting, vermiculite offers a cost‑effective, sustainable choice for modern industrial and construction fireproofing needs.
