MasterFlame JS 225 - High performance, intumescent, firestop sealant
What is MasterFlame JS 225?
MasterFlame JS 225 is a graphite based
intumescent firestop sealant which when exposed
to fire strongly expands protecting penetrations
including cables, cable bunches, cable trays,
plastic and metallic pipes.
MasterFlame JS 225 maintains the integrity and
insulation performance of the seal through
masonry, plasterboard and pre-coated firestop
board MasterFlame B 302.
MasterFlame JS 225 has excellent non-slump
properties coupled with ease of application.
What is MasterFlame JS 225 used for?
MasterFlame JS 225 is intended for use in
service penetrations through walls and floors
where fire integrity and insulation needs to be
preserved. Under fire conditions the product swells
and exerts pressure to the surrounding substrates
leading to closure of the penetration. The integrity
and insulation is then maintained by the stability of
the remaining product char.
