Polyisocyanurate (PIR) and Polyurethane (PUR) foams are widely used in the gas liquefaction industry thanks to their excellent behaviour at critical temperatures such as those in cryogenic applications.
Being strongly resistant to thermal shocks, as well as chemically inert, our CORAFOAM® polyurethanes and polyisocyanurates can withstand a wide range of operating temperatures from strong cryogenic (liquid nitrogen -196 °C) up to about 120 °C, granting the best compromise in terms of cost/efficiency. For these reasons they are massively used in the most critical cryogenic applications where the saving of frigories is vital for the efficiency of the running plant
