PU28 is a low-density open cell foam and weighs only 28kg/cm3. Within the PU foam density range, PU28 is considered “higher density” polyurethane foam. It is a soft foam but is reasonably heavy duty for longer lasting use. This foam’s higher density renders it more resistant to breakdown and degradation, and its increased firmness aids in the casing of frequently used but delicate items that must be packaged snugly, like instruments or technical equipment. It can also serve as entry-level soundproofing.
