Product Introduction:Firestop seals are a type of firestop material specifically designed for penetration holes in cables, pipes, etc. Upon exposure to fire, they rapidly expand to form a dense carbonized layer, effectively blocking the spread of flames and high temperatures, ensuring the safety of the building structure. Their flexible and moldable properties accommodate various irregular gaps, providing a durable fire barrier.

　　Product Advantages:Utilizes an environmentally friendly flame-retardant formula, non-toxic and non-corrosive, and meets national fire prevention standards. Offers a high expansion ratio (≥10x), with a fire resistance of over 3 hours, and is easy to install—simply pack and compact to achieve sealing. Features self-adhesiveness, requiring no additional fastening, and resists chipping and peeling over long-term use.

　　Product Application:Fire-resistant seals for wall penetrations of cable trays and metal piping in substation, data centers, high-rise buildings, etc., particularly suitable for stringent fire safety industrial scenarios like nuclear power and chemical industries, serving as a core component of the passive fire protection system.
