Product Introduction:Firestop packings are a type of firestop material specifically designed for sealing 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 malleable properties accommodate various irregular gaps, providing a durable fire barrier.

　　Product Advantages:Utilizes eco-friendly flame-retardant formula, non-toxic and non-corrosive, meets national fire-resistant standards. High expansion ratio (≥10 times), fire resistance of over 3 hours, and easy installation—simply fill and compact to achieve sealing. Features self-adhesiveness, no additional fixation required, and does not flake or fall off over long-term use.

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