As you may have expected, open-cell spray foam is similar to closed-cell in nature. It just has a lesser R-value. While most closed-cell spray foams will be above 6.0 per inch, open-cell is much ...

Polyurethane foam can be divided into two categories, such as open-cell and closed-cell foam. The former is a plastic with incomplete cell walls and include holes through which air and liquid can ...

We used polyurethane foam with open cell walls. The CFH-30 had cells of ∼ 600 μm in diameter and the CFS had cells of ∼ 300 μm in diameter. Each cell had several pores.

Polyurethane foam is perhaps the most widely used foam material. Open-cell polyurethane foams are odorless, breathable, fire retardant, and resist bacteria, dust, and oils. They also absorb sound.
