  • Evaporative foam risers with exothermic topping
    Patent number: 7270171
    Abstract: This invention consists of the use of an evaporative foam riser made with expanded polystyrene and with a cavity on top that contains an exothermic mixture. The reaction of the exothermic material, which is set off when it comes in contact with the metal, prolongs the solidification time of the riser thus rendering it more effective.
