Characteristics

1. Excellent gap-filling performance:Expands rapidly (20-60 times volume expansion rate) to fill irregular gaps, cracks, and voids (5mm-100mm) tightly, eliminating air leakage and preventing moisture intrusion.
2. Dual functions of insulation & energy saving:Closed-cell structure provides outstanding thermal insulation (thermal conductivity ≤ 0.035 W/(m·K)) and sound absorption, reducing energy loss in buildings and blocking noise transmission.
3. Strong adhesion versatility:Bonds firmly to porous (concrete, wood, masonry) and non-porous (metal, plastic, glass) substrates without primers, ensuring reliable bonding and structural stability.
4. Waterproof & moisture-proof property:Dense closed-cell structure resists water penetration, preventing mold growth and material corrosion; suitable for both indoor and outdoor damp environments.
5. Lightweight & load-reducing advantage:Low density (11-30 kg/m³ for general construction use, 30-70 kg/m³ for industrial grade) reduces structural load while maintaining sufficient compressive strength (≥ 0.3 Mpa).
6. Fast curing & convenient application:Achieves surface dryness in 15-30 minutes and full curing in 24 hours at room temperature; available in tube/gun-applied types for easy extrusion and precise positioning.
7. Chemical stability & durability:Resists aging, UV radiation, and common chemicals; maintains performance in extreme temperatures (-50℃ to 100℃) without cracking or crumbling, with a service life of 10+ years.
8. Eco-friendly & safe formula:Low VOC emissions comply with international standards (EU REACH, US EPA); non-toxic and odorless after curing, suitable for enclosed spaces like homes, offices, and vehicles.

Application Scenarios

1. Building Construction & Renovation:Fills gaps between door/window frames and walls, seals masonry cracks, roof penetrations (pipes, vents), and floor-wall joints. Enhances thermal insulation, soundproofing, and waterproofing for residential, commercial, and industrial buildings.
2. Door & Window Installation:Seals irregular gaps around aluminum alloy, PVC, or wooden door/window frames to prevent air leakage, water intrusion, and noise transmission. Improves energy efficiency and structural stability of the installation.
3. Industrial Equipment & Appliance Manufacturing:Used for thermal insulation and shock absorption in refrigerators, freezers, and HVAC systems; seals gaps in automotive door panels, engine compartments, and electronic device casings (waterproof/dustproof).
4. Pipeline & Duct Sealing:Seals gaps around water supply pipes, drainage pipes, gas pipes, and air conditioning ducts. Prevents water leakage, gas leakage, and energy loss, suitable for both indoor and outdoor pipeline projects.
