Fire-retardant fireproof boards are manufactured by mixing high-quality vermiculite expanded at 800°C with fireproof adhesive in a specific ratio. The mixture undergoes molding and high-temperature curing to form fireproof boards. These boards feature light weight, high strength, excellent toughness, thermal insulation, fire resistance, and ease of installation. With Class A1 fire rating and Class ZA1 material smoke toxicity rating, these boards are widely applicable in high-rise frame structures, communication ducts, fireplaces, ovens, high-speed rail systems, kilns, fire door cores, aluminum plants, steel mills, and related industries.
