s Provides excellent
environmental sealing
s 3:1 and 4:1 shrink ratios
s High strength bonding
s Operating temperature
-55°C to +110°C
Atum is a semi-flexible, heat-
shrinkable tubing with a
meltable adhesive inner lining
designed to provide moisture
proof sealing to a wide range
of substrates such as electrical
wire splices, cable jackets,
wire breakouts and electrical
components.
The high shrink ratios mean
that only seven sizes are
required to cover a wide
range of substrate diameters.
Typical applications are
environmental sealing of
electrical components including
wire splices and harness
breakouts as well as
sealing cable ends against
moisture ingress.
