Product Description:Firestop seals are a type of fire-resistant material specifically designed for sealing through 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 moldable characteristics accommodate various irregular gaps, providing a durable fire barrier.

　　Product Advantages:Utilizes eco-friendly flame-retardant formula, non-toxic and non-corrosive, and meets national fire prevention standards. High expansion ratio (≥10x), fire resistance exceeds 3 hours, and easy installation—simply pack and compact for sealing. Self-adhesive, no additional fastening required, and won't flake or fall off over long-term use.

　　Product Application:Fire-resistant sealing for cable bridge holes and metal pipe penetrations in substation, data centers, high-rise buildings, etc., especially suitable for industries with stringent fire resistance requirements like nuclear power and chemical industries, serving as a core component of the passive fire protection system.
