Fire-retardant PU FOAM B1
Exceptional Fire Retardancy (Class B1/B Certified):
This foam sealant is specially engineered with fire-retardant additives that meet stringent international standards (such as GB 8624 B1, EN 13501-1). In the event of fire, it exhibits excellent resistance to flame propagation and is designed to be self-extinguishing upon removal of the ignition source. It forms a protective char layer that helps delay the spread of flames and hot gases through openings, making it a critical component for passive fire protection in door and window perimeters, thereby enhancing overall building safety.
High Hardness and Dimensional Stability:
Unlike standard insulating foams that remain soft, this product cures to a high-hardness, rigid structure with minimal long-term shrinkage. This provides outstanding mechanical strength and load-bearing capacity, ensuring that installed doors and windows remain securely fixed, resistant to sagging, and unaffected by wind pressure or operational stresses. The rigid seal also prevents compression over time, guaranteeing a permanent, gap-free fit.
Superior Soundproofing and Acoustic Insulation:
The high-density, closed-cell structure of the cured foam acts as an effective sound-dampening barrier. It significantly reduces the transmission of airborne noise (such as traffic, urban sounds, and voices) through gaps around window and door frames. This contributes to a noticeably quieter, more peaceful, and comfortable indoor environment, meeting the growing demand for enhanced acoustic comfort in modern construction.
Excellent Adhesion and Airtight/Watertight Seal:
It adheres tenaciously to a wide variety of common construction materials including concrete, brick, wood, PVC, and metals. By completely filling irregular cavities and gaps, it creates a continuous air and weather barrier. This superior seal blocks drafts, moisture infiltration, and dust, dramatically improving the building's thermal insulation (reducing heating/cooling costs) and protecting against water damage.
Building & Construction Industry
Firestop Sealing for Openings: Used to seal gaps around penetrations (e.g., pipes, cables, ducts) in walls, floors, and ceilings to prevent the spread of fire, smoke, and toxic gases between compartments, complying with passive fire protection regulations.
Door and Window Installation: Applied as a high-strength adhesive and gap filler for installing window frames, door frames, and curtain walls. It provides structural support, airtight/watertight sealing, thermal insulation, and sound dampening, while contributing to the fire rating of the assembly.
Joint and Cavity Filling in Walls/Roofs: Fills construction joints, expansion joints, and cavities in masonry or prefabricated panels, enhancing the building’s fire compartmentalization, thermal efficiency, and weather resistance.
Industrial Manufacturing & Facility Maintenance
Fire-Rated Enclosures and Electrical Installations: Seals openings in electrical cabinets, control panels, fire-rated enclosures, and cable trays to maintain their fire integrity and prevent flame propagation through wiring channels.
HVAC and Ductwork Sealing: Used to seal joints and gaps in heating, ventilation, and air conditioning (HVAC) ducts, especially in systems requiring fire-rated barriers, to improve system efficiency and prevent smoke leakage in case of fire.
Equipment Base Fixation and Insulation: Secures and seals industrial equipment, machinery bases, or piping supports, providing vibration damping, thermal insulation, and fire protection for critical infrastructure.
Transportation & Marine Applications
Shipbuilding and Marine Engineering: Employed for fireproofing and sealing in engine rooms, bulkheads, deck penetrations, and cabin structures on ships and offshore platforms, meeting maritime fire safety standards (e.g., SOLAS requirements).
Railway and Automotive Manufacturing: Used in the assembly of railway carriages, commercial vehicles, and buses to fill gaps in body panels, firewall partitions, and around windows, ensuring fire safety, reducing noise, and improving structural rigidity.
Specialized Applications
Data Centers and Server Rooms: Seals cable entry points and openings in raised floors or walls to maintain fire barriers and prevent airflow leakage, crucial for both fire safety and cooling efficiency.
Renovation and Retrofitting Projects: Ideal for upgrading fire safety in existing buildings by filling outdated or deficient seals around services and structural elements without major demolition.
