EPS
(
Expanded
Polystyrene
)
is
a
lightweight,
rigid,
plastic
foam
insulation
material
produced
from
solid
particles
of
polystyrene.
Expansion
is
achieved
by
virtue
of
small
amounts
of
gas
dissolved
into
the
polystyrene
base
material
during
production.
The
gas
expands
under
the
action
of
heat,
applied
as
steam,
to
form
perfectly
closed
cells
of
EPS.
Expanded Polystyrene with relatively low density (1.05g/cm3 ) ,low thermal conductivity ,low water absorption,impact resistencce,heat insulation ,sound insulation,moistureproof,vibration damping and excellent dielectric properties,widely used in mechanical equipmemnt ,instruments and meters ,household electric ,crafts and other valuable products easilly damaged,shockproof packaging materials as well as the fast food packaging.
Flame retardant EPS grades confer excellent processingand product propertiesn Consistent raw bead and good fluidity of foamed bead Rapid expansion Relatively low density in second-time expansion.Excellent flame retardation with the US UL Product Security Certification.Wide range of operation and suitablefor various block machines ,automatic ,machines and manual presses.Fine cell,beautiful and flat appearance .Low shrinkag rate of block in molding .Recommended 40-70 expansion ratio to increase as per several-time expansion.
