High-Tech PU Foam is one component multipurpose polyurethane foam that dispenses form. Hi-Tech PU Foam will expand and cure by moisture in the air and used for a wide range of building applications. It is very good for filling and sealing capacities, excellent mounting capacities, stable, high thermal and acoustical insulation. Hence ideal for UPVC, masonry, brick, block work, glass, steel, aluminum, timber and other substrates (except PP, PE and Teflon). Hi-Tech PU Foam suitable for installing, fixing and insulating of door and window frames, filling and sealing of gaps, joint, openings and cavities, connecting of insulation materials and roof construction, bonding and mounting, insulating, the electrical outlets and water pipes, heat preservation, cold and sound insulation.
