Shijiazhuang Chenxing Industrial Co., Ltd. possesses extensive experience in manufacturing vermiculite fireproof boards. Equipped with comprehensive facilities and rich production expertise, the company produces vermiculite boards using premium Xinjiang vermiculite as raw material. These boards are non-toxic, odorless, asbestos-free, and do not emit gases harmful to human health even when heated to 1200°C, qualifying them as green and environmentally friendly materials. Samples submitted to third-party authoritative testing institutions were evaluated according to GB8624-2012 “Classification of Combustion Performance of Building Materials and Products” and GB/T20285-2006 “Hazard Classification of Material Smoke Toxicity”. The combustion performance achieved GB8624 (Class A1), while material smoke toxicity reached the safety level (ZA2). These results fully meet design standards.
Vermiculite insulation boards have a wide range of applications. Their primary raw materials are expanded vermiculite and a specific amount of inorganic binder, processed into boards through complex procedures such as hot or cold pressing. Density typically ranges from 650 to 900 kg/cm³. Panel thickness generally exceeds 2cm. As a new type of thermal insulation material, extruded vermiculite boards offer thermal insulation, heat resistance, and fireproofing properties. Chenxing's vermiculite boards are categorized by application into several major types: partition walls or dividers (G), wall insulation (J), fire door cores (F), steel structure protection panels (GJ), and interior decoration (S). Widely used in fire door cores, high-end kitchenware, furniture, fireplace linings, wall materials, tunnel fireproofing, aluminum channel insulation, ship hull panels, kilns, fireplace insulation, and various industrial insulation applications. The factory accepts custom-shaped vermiculite board production, tailoring specifications, dimensions, thickness, density, and patterns according to specific user requirements.
