Polyurethane (PU) Foam Sealant

Polyurethane (PU) foam is a versatile, high-performance material widely used in the construction and industrial sectors for sealing, insulating, and filling gaps. Upon application, the liquid polyurethane reacts with moisture in the air to expand rapidly, forming a durable, closed-cell foam that provides excellent thermal and acoustic insulation while creating an airtight and watertight barrier.

This product is ideal for sealing joints around windows, doors, and pipes, as well as for filling voids in concrete, masonry, and metal structures. Its strong adhesion to various substrates ensures long-lasting performance, while its lightweight nature minimizes structural load. PU foam is also valued for its ease of application via standard dispensing guns and its ability to be trimmed and painted after curing.

• Excellent thermal and acoustic insulation properties
• High expansion ratio for filling large gaps and voids
• Strong adhesion to wood, metal, concrete, and plastics
• Weather-resistant and durable once cured
• Easy to apply, trim, and finish
