Advantages
Exceptional Gap-Filling Versatility:Expands 20-60 times its original volume rapidly, seamlessly filling irregular gaps, cracks, and voids (5mm-100mm) regardless of shape. Eliminates air leakage and bridges gaps between different materials, ensuring comprehensive sealing without dead corners.
Dual Thermal & Acoustic Insulation:Closed-cell structure delivers outstanding thermal insulation (thermal conductivity ≤ 0.035 W/(m·K)) and sound absorption. Reduces energy loss in buildings by blocking heat transfer, while dampening noise transmission—ideal for energy-saving and soundproofing projects.
Superior Waterproof & Moisture-Proof Performance:Dense closed-cell matrix resists water penetration and moisture intrusion, preventing mold growth, material corrosion, and structural damage. Suitable for both indoor and outdoor damp environments, maintaining sealing integrity even in long-term humid conditions.
Strong Multi-Substrate Adhesion:Bonds firmly to porous (concrete, wood, masonry) and non-porous (metal, plastic, glass) substrates without the need for primers. Forms a durable, non-peeling bond that enhances structural stability and long-term sealing reliability.
Application Scenarios
Building Construction & Renovation
Seals gaps between door/window frames and walls, roof penetrations (pipes, vents, chimneys), floor-wall joints, and masonry cracks. Enhances thermal insulation, soundproofing, and waterproofing for residential, commercial, and industrial buildings—reduces energy loss and prevents moisture intrusion.
Door & Window Installation
Fills irregular gaps around aluminum alloy, PVC, or wooden door/window frames. Blocks air leakage, water seepage, and noise transmission, improving energy efficiency and structural stability. Suitable for both new installation and renovation projects.
Industrial Equipment & Appliance Manufacturing
Used for thermal insulation, shock absorption, and sealing in refrigerators, freezers, and HVAC systems. Seals gaps in automotive door panels, engine compartments, electronic device casings, and generator enclosures—provides waterproof, dustproof, and vibration-resistant protection.
Pipeline & Duct Sealing
Seals gaps around water supply pipes, drainage pipes, gas pipes, and air conditioning ducts (indoor/outdoor). Prevents leakage, energy loss, and cross-contamination, ensuring the safe operation of pipeline systems in buildings, factories, and public facilities.
