Vibrant VIBRANT-080 General Purpose PU Foam 750ml is a versatile material used for various applications, including insulation, sealing, and filling gaps. Polyurethane foam is a type of polymer material that is created by combining two main components: isocyanate and polyol. When these components are mixed, they undergo a chemical reaction, creating a foam that expands and solidifies.

PU foam is used in a wide range of applications, including construction, automotive, upholstery, packaging, and more. It is known for its thermal insulating properties, making it useful for insulating buildings and appliances. It can be used to seal gaps and cracks, preventing air and moisture infiltration. Despite its ability to expand and fill spaces, PU foam remains relatively lightweight.
