BARC has developed a Intumiscent Rigid Polyurethane Foam. The Foam is used as a core packaging material for various radioactive enclosures providing heat insulation and energy absorption properties. The process for production of polyurethane based plastic foams uses urethane groups to provide a wide range of mechanical properties, by reacting relatively higher molecular weight polyhydroxy compounds with organic polyisocyanates in the presence of catalysts and blowing agents.
