B1 FIRE RATED PU FOAM, is a single component, moisture
curing, self-expanding, ready to use polyurethane foam with propellants which
are completely harmless to ozone layer. It has a fire rating of up to 235
minutes in certain configurations. High quality PU straw foam recommended for
sealing applications where fire resistance is required. It is designed for easy
dispensing through the straw adapter included with each can.
