Feature

1. High Expansion Rate
   
   
   Expands 20–60 times its original volume, filling irregular gaps, cracks, and voids (5mm–100mm) seamlessly without dead corners.
2. Closed-Cell Insulation Structure
   
   
   Forms a dense closed-cell matrix after curing, delivering excellent thermal insulation (thermal conductivity ≤ 0.035 W/(m·K)) and sound absorption performance.
3. Strong Multi-Substrate Adhesion
   
   
   Bonds firmly to concrete, wood, metal, plastic, glass, and masonry without primers, ensuring durable, non-peeling sealing effects.
4. Superior Waterproof & Moisture-Proof
   
   
   Resists water penetration and moisture intrusion effectively, preventing mold growth, material corrosion, and structural damage in damp environments.

Application Scenarios

1. 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.
2. 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.
3. 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.
4. 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.
