CORAFOAM® Low density


CORAFOAM® Low density polyurethane and polyisocyanurate foams are PUR/PIR rigid foams mainly used for thermal insulating purposes, thanks to their very low thermal conductivity and their high insulating power.

The performance of polyurethane/polyisocianurate foams is expressed at best in the cold chain rather than with hot temperatures, to assure insulation both in transport of perishable good (food, medicines, etc.) and, in case of polyisocyanurates, in applications of HVACR and industrial insulation . They are also employed successfully as filling material of sandwich and composite structures in marine and transportation.

The density of our PIR/PUR low density foams runs from 33 to 60 kg/m3. Different families of foams are available, according to the special requirements of the specific application, (e.g. fire behavior).

Polyurethane/polyisocyanurate foams are available in sheets, blocks or special machined items and special shapes (shells for piping, elbows, tees, valves, flanges...etc) realized on customers’ request.
