Product Description:Firestop seals are a type of firestop material, specifically designed for penetration holes in cables, pipes, etc. When exposed 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 characteristics adapt to 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. High expansion ratio (≥10 times), fire resistance of over 3 hours, and easy installation—simply pack 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:Fireproof sealing for wall penetrations of cable trays in substation, data centers, high-rise buildings, etc., and metal pipe penetrations, especially suitable for industrial scenarios with stringent fire rating requirements like nuclear power and chemical industries, serving as a core component of the passive fire protection system.
