US150 Fire Barrier Foam

Description:
Fire Barrier Foam is a two component flexible product, consisting of separate A and B liquid
components which, when mixed, forms a medium-density fire retardant foam.
US150 / US110 is designed to seal large openings and multiple penetration areas such
as cablebundles, cable trays and metallic pipes.
Prior to foaming, the liquid components remain fluid allowing effortless sealing of any size and
shape opening.
After exposure to 1x10⁶ Gy (1x10⁸ rad) of neutron orgamma radiation, US150 &US110
will maintain full firestop performance characteristics 50 plus years.
