NBR Nitrile Rubber Tubes

Aerofoam® NBR Nitrile Tubes are made from closed cell rubber foam, which has a microcell, non porous structure and closed cell content bigger than 90%. They cover a wide range of diameters and thicknesses, matching the most used pipe sizes. The Aerofoam® NBR tubes have a very good dimensional stability and offer an excellent protection against condensation, thermal loss and sound transfer. The flexibility of the tubes and the powder applied inside them, allowing a low friction movement, improve significantly the installation time.

The tubes represent no hazard to the human health, being used no CFC or HCFC in their production and having a very low VOC level. They are considered environmental friendly products (with low Ozone Depletion Potential – ODP – and Global Warming Potential – GWP) and comply with the LEED requirements, helping buildings to get more LEED points.
