Cellular Rigid Polyurethane Foam Properties

Cellular rigid polyurethane foam has larger pores to resemble cancellous bone. Cell size ranges from 0.5 to 2.0mm diameter for this primarily closed cell foam. Variation in foam density is ±10% and is available in a range of densities from 0.12g/cc to 0.32 g/cc (7.5pcf to 20pcf).
