This
halogen-free, mineral based flame retardant is made of modified
expandable
graphite
which can be used
in
polyurethane hard foam/soft foam,
polyethylene,
polypropylene, resin, coating and other
plastics.
Expandable
graphite flame retardant combines two modes of action in one
additive: the
flammability of the component is reduced on
the one hand and, on the other
hand,graphite forms a protective expanded
layer in case of a fire. A large number of
tiny
holes are
formed, which can absorb the smoke generated in the combustion
process.
With
graphite flame retardant, cold room PU can reach B1 degree with
oxygen index
improved by
***0 without destroying PUs physical
properties.
Hydrophobic
suspension and excellent flame retardant effect, good
compatibility with
organic
system, which can solve the problem of water absorption of flame
retardant.
