CORAFOAM® Special foams represents the cutting edge of our polyurethane (PUR) and polyisocyanurates (PIR) foam production. Every one of them is a uniquely developed PUR/PIR foam that contains our best know-how in order to solve a particular problem.
One example of our Special Foams is CORAFOAM® PB 50 M1-HC, the most reliable polyisocyanurate (PIR) foam approved in extreme cryogenic applications.
Developed in 2003 to face the ban of HCFC blowing agents in the European Union, this polyisocyanurate (PIR) foam rapidly became a key product for the insulation of LNG Terminals worldwide thanks to its excellent performance at the working temperatures of these plants (-165° to +40°C).
The R&D of PB 50 M1-HC has focused on the most strict insulation specifications for industrial plants including CINI 2.07.01 and SHELL DEP 30.46.00.31, which our foams fully comply with.
This special polyisocyanurate PIR foam is supported by a complete set of independent laboratory certifications, and has been successfully installed in various LNG and ethylene plants, including:
- Exxon Baytown Ethylene
- Sintech Ethylene Plaquemines
- Freeport LNG
- Shell Franklin Ethylene
- LACC Ethylene
CORAFOAM® PB M1-HC
Together with our polyurethane and polyisocyanurate foams, we also offer a service to produce our polyurethane foam in the most faraway places in the world: PEGASUS Mobile Foaming Units, machines that can be easily shipped and transported in containers.
PEGASUS machines are not designed for sale, our technicians take our technology abroad and operate the units, so that both production and supervision remain under the strict control of DUNA-Corradini, assuring the best quality of foam wherever it is needed.
Another example of these very special foams is the Fiberglass Reinforced Polyurethane Foam (CORAFOAM® RV), which combines extreme lightness and insulation with very strong resistance.
