Our expanding PU foam for gap filling is an engineering-grade, one-component polyurethane foam sealant, specially developed for construction contractors, building material wholesale distributors, door & window manufacturers, and large-scale engineering project purchasers. As a high-performance polyurethane foam sealant, it is designed for gap filling, sealing, thermal insulation and acoustic attenuation, with a high-expansion, anti-shrinkage formula that solves common construction pain points such as gap air leakage, poor insulation, and post-construction shrinkage. The aldehyde-free, CFC-free formula complies with global green building standards, making it suitable for both residential and commercial engineering projects, and an ideal choice for bulk procurement in the construction industry.
Our high-expansion gap filling foam delivers exceptional expansion performance, with a single 750ml can achieving up to 70 liters of foam volume, expanding up to 75 times its liquid volume, effectively filling large gaps and cavities with just 40% cavity filling to accommodate full expansion. The fast-curing formula becomes tack-free in approximately 10 minutes, allows cutting and shaping in 10-30 minutes, and achieves full curing within 1-1.5 hours, greatly speeding up on-site construction progress and shortening project cycles for engineering contractors. The anti-shrinkage formula ensures long-term dimensional stability, with no cracking or shrinkage after curing, maintaining a reliable seal for decades.
As an aldehyde-free PU foam sealant, our product is formulated without added formaldehyde and chlorofluorocarbons (CFCs), minimizing environmental impact and indoor air pollution, strictly complying with ISO14001 environmental management system standards and global green building requirements. It provides strong, durable adhesion to most common construction materials including concrete, wood, metal, PVC and wall coatings, even on slightly damp surfaces, with no special primer required, simplifying on-site construction processes. The cured foam also delivers excellent thermal insulation, acoustic attenuation, and moisture-proof waterproof performance, effectively blocking air and moisture infiltration, improving building energy efficiency.
For construction project purchasers and bulk building material distributors, our waterproof polyurethane foam for construction offers superior cost efficiency, with high yield per can reducing the number of products required for a single project, lowering material procurement costs. Our fully automatic production lines ensure consistent expansion ratio and formula stability across every batch, reducing on-site waste and rework rates. The long shelf life and stable storage performance also reduce inventory management costs for wholesale distributors, making it a reliable choice for long-term cooperative procurement.

Our anti-shrinkage engineering PU foam is widely used across the construction and building materials industry. In building engineering, it is the core product for door and window installation, used to seal the perimeter gaps between door/window frames and walls, providing a reliable airtight and waterproof seal. It is also used for filling cracks in walls, pipe penetrations, vent ducts and wire outlets, blocking air and moisture infiltration. For thermal and acoustic insulation projects, it is used to fill cavities in partition walls and roof structures, improving building thermal insulation and soundproofing performance. It also has wide applications in gardening and landscaping for fixing and sealing, as well as in packaging and transportation for shock-absorbing buffering of fragile and valuable goods.
