Brief Introduction

Engineered for construction contractors, building material wholesalers, door and window manufacturers, and large-scale project buyers, this expanding PU foam is a one-component, engineering-grade polyurethane sealant. It delivers high-expansion, anti-shrinkage performance specifically designed to address common on-site issues such as air leakage around gaps, poor thermal insulation, and post-application shrinkage. Ideal for gap filling, sealing, thermal insulation, and soundproofing, the aldehyde-free and CFC-free formulation meets global green building standards. Suitable for both residential and commercial projects, it is a reliable choice for bulk procurement in the construction industry.

Core Features & Wholesale Competitive Advantages

High Expansion & Fast Curing

This high-expansion gap-filling foam offers outstanding volumetric performance. One 750ml can yields up to 70 liters of cured foam – an expansion ratio of 75 times its liquid volume. To accommodate full expansion, only 40% of the cavity needs to be filled. The rapid-curing formulation becomes tack-free in roughly 10 minutes, can be trimmed or shaped within 10–30 minutes, and fully hardens in just 1 to 1.5 hours. This significantly accelerates on-site installation and shortens project timelines for contractors. The anti-shrinkage formula ensures long-term dimensional stability, preventing cracks or shrinkage after curing and providing a durable seal for decades.

Eco-Friendly & Engineering-Grade Performance

Our aldehyde-free PU foam sealant contains no added formaldehyde or CFCs, reducing both environmental impact and indoor air pollution. It strictly complies with ISO14001 environmental management standards and global green building requirements. The foam bonds strongly and durably to most common construction substrates – including concrete, wood, metal, PVC, and coated walls – even on slightly damp surfaces, with no special primer needed. This simplifies on-site application. Once cured, the foam delivers excellent thermal insulation, acoustic damping, and moisture-proof / waterproof performance, effectively blocking air and water infiltration to enhance building energy efficiency.

Cost Efficiency for Bulk Buyers

For project purchasers and building material distributors, this waterproof polyurethane foam delivers superior cost efficiency. High yield per can reduces the number of units needed per project, lowering material procurement costs. Our fully automated production lines ensure consistent expansion ratio and formula stability across every batch, minimizing on-site waste and rework. The long shelf life and stable storage performance also help wholesalers reduce inventory management costs, making this foam a reliable choice for long-term, bulk purchasing partnerships.

Industrial Applications of PU Foam Sealant

Our anti-shrinkage engineering PU foam serves a wide range of applications in construction and building materials. In building projects, it is primarily used for door and window frame perimeter sealing, ensuring airtight and waterproof joints, as well as for filling cracks in walls, pipe openings, vents, and wire outlets to block air and moisture. For insulation work, it fills cavities in partition walls and roofs to improve thermal and acoustic performance. It is also useful in gardening and landscaping for fixing and sealing, plus in packaging and transport as a shock-absorbing buffer for fragile or valuable items.
