CB80 Fiber Composite Fireproof Board
Category: Fire-Resistant Range
Product Details
CB80 fiber‑reinforced fireproof board, as an industrial fire‑resistant material, boasts core performance characterized by resistance to 1500°C high‑temperature flame erosion, while simultaneously meeting both flame‑retardant and insulating requirements. During flame exposure, it exhibits no powder shedding, and its surface remains free of loose residue after ablation.
Product features: Resistant to high-temperature flame erosion up to 1500°C, with no powder shedding and excellent insulation.
Application areas: CB80 is suitable for industrial‑grade fire‑resistant applications that also require a certain load‑bearing capacity.
