Product Introduction:Firestop seals are specialized fire-resistant sealing materials designed for贯穿holes in cables, pipes, etc. Upon exposure to fire, they rapidly expand to form a dense char layer, effectively blocking the spread of flames and high temperatures, ensuring the safety of the building structure. Their flexible and malleable characteristics accommodate various irregular gaps, providing a durable fire barrier.

　　Product Advantages:Utilizing an environmentally friendly flame-retardant formula, non-toxic and non-corrosive, it has passed the national fire safety standard certification. It boasts a high expansion ratio (≥10 times), with a fire resistance limit of over 3 hours, and is easy to install—simply fill and compact to achieve sealing. It is self-adhesive, requiring no additional fastening, and resists chipping or peeling over long-term use.

　　Product Application:Fire-resistant seals for wall penetrations and metal pipe passages in substation, data centers, high-rise buildings, etc., especially suitable for stringent fire protection grade industrial scenarios such as nuclear power and chemical industries, and is a core component of the passive fire protection system.
