ATUM
Semi-flexible, general purpose adhesive-lined, moisture proof heat-shrinkable tubing.
Provides excellent environmental sealing, 3:1 and 4:1 shrink ratios,
high strength bonding, 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 vsplices,
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.
