Expanding Polyurethane Foam

Expanding Polyurethane Foam

What is an expanding Polyurethane foam?

Expansive Polyurethane Foam is a product made up of the chemical reaction between two elements, isocyanate and polyol. With rigid foam properties, the expansive polyurethane foam is characterized by being a product with the ability to adapt according to the size of the surface to which it is applied

Widely used in construction, and in several other market segments, an expansive polyurethane foam is a type of sealant, also known to be an elastic polyurethane adhesive. It is used by specialized professionals to seal, fix or insulate certain materials used in construction.

Main functions of expansive polyurethane foam

Fixing and installing jambs, aluminum, iron and wood windows, filling expansion joints, cracks and holes, insulating pipes and protecting electricity panels are the most common purposes performed by construction managers. In addition, the thermal and acoustic insulation capacity of the expansive polyurethane foam is excellent for roofing structures. Air conditioning boxes, on the other hand, depend on the material for fixation and protection, in addition to other refrigeration and heating equipment that use expansive polyurethane foam as a seal.

Expanding Polyurethane Foam


The high performance of expansive polyurethane foam is related to the ability to mold surfaces and environment. After that, the material's rigidity property appears and it adapts by filling and sealing the space where it was prepared.

The expansive polyurethane foam has the following properties:

  • Insulates different materials or environment;
  • Ensures great cost-benefit for being economical and effective;
  • Eliminates noise and vibrations from the appliances, providing peace of mind, especially when it comes to air conditioning;
  • Has a high capacity to transfer heat to the external environment or other equipment;
  • Presents resistance when exposed to pressure and weather;
  • Supports different actions and shows resilience.
