Product Introduction:Firestop seals are a type of fire-resistant material specifically designed for sealing through-penetrations in cables, pipes, and the like. 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 properties accommodate various irregular gaps, providing a durable fire barrier.
Product Advantages:Utilizes eco-friendly flame-retardant formula, non-toxic and non-corrosive, meeting national fire safety standards. High expansion ratio (≥10x), fire resistance exceeds 3 hours, and easy to install—simply pack and compress to achieve sealing. Self-adhesive, no additional fixation required, and won't crumble or peel off over long-term use.
Product Application:Fireproof seals for cable bridge holes and metal pipe penetration in substation, data center, high-rise buildings, etc., particularly suitable for industrial scenarios with strict fire rating requirements like nuclear power and chemical industries, and is a core component of passive fire protection systems.
