[0002] Flame-retardant sheet material is a material with flame-retardant properties, usually made of flame-retardant materials, such as flame-retardant polymers, flame-retardant glass fibers, flame-retardant rock wool, etc. These materials are not easy to burn when exposed to flames, or burn slowly, and can effectively reduce the losses caused by fire, playing a role in fire isolation and protection. Double-layer flame-retardant sheet material is usually composed of two layers of flame-retardant material with heat insulation and sound insulation material in between, and has multiple functions such as fire prevention and sound insulation.
