These gaskets are realized wrapping with
one or more metallic wire mesh a foam (polyurethane,
neoprene and silicone).
To use where the closing are irregular or
where a weak is desired strength of closing, but also a
certain degree of protection is in demand from the dust
or damp.
The installation can simply be effected
for attrition or, in absence of throats on the
wisecracks, through adhesive strip.

Wrapping material:
SS (Stainless Steel AISI304):
Stainless Steel. Material with good resistance to the
corrosion and elevated superficial hardness therefore
to use in presence of notable abrasive strengths.
CU (Copper):
Copper. This material manifests the best
characteristics of screening especially in presence of
predominantly electromagnetic field.
BR (Brass):
Brass. Good characteristics of screening also in
magnetic field.
Foam core:
POLYURETHANE FOAM:
open/close cells, anthracite colour, with density from
30 to 95 Kg/m3s, with good elastic recovery and
permanent deformation to compression (50%) of 3%,
field of temperatures of job from -40°C to +85°C, also
with self extinguishing according to the norms
UL94-V0.
NEOPRENE:
polymer expanded to closed cellular structure, of
black colour, with characteristics of good resistance
to the bad weather, to the flame, to the oils and the
chemical products. The duration is boundless if under
normal environment conditions. Density 150 kg / m3,
hardness 45 Shore, resistance to the fire UL-94HB,
water's absorption 0.7%, resistance to the ozone (200
ppmh/30°C/48hs): any crack, temperature of service
from -40°C to +85°C.S
SILICONE:
seed-organic polymer, waterproof, with characteristics
of good stability and duration, resistant to extreme
temperatures (from -55°C to +200°C), light, ozone,
damp, chemicals. The silicone is expanded for the
sections full and solid for the sections tube
circulars, in both cases with good elastic resumption.
