ATUM

High expansion ratio, adhesive-lined

heat-shrinkable tubing

ATUM tubing is radiation-crosslinked,

heat-shrinkable, and adhesive-lined to

provide environmental sealing in a wide

variety of electrical applications. The

product is typically used to seal

connector backshells and cable

breakouts and to repair damaged cable.

ATUM has an internal adhesive coating

that, when heated, melts and flows to

form a positive environmental seal.

The coating adheres to the outer

Temperature rating

Full recovery temperature:

Continuous operating temperature:

tubing and the surface below, creating

an excellent barrier to moisture

penetration. The adhesive bonds to a

wide variety of plastics, rubbers, and

metals, including PVC, polyethylene,

rubber, and aluminum.

Because the tubing and adhesive

are flexible, the moisture seal

withstands bending of the substrate.

This flexibility makes ATUM tubing

ideal for cable repair.

125 ° C

– 55 ° C to 110 ° C

ATUM tubing is available with expansion

ratios of both 3:1 and 4:1. These high

expansion ratios make it possible to

repair cables without removing

connectors. Just a few sizes of ATUM

tubing cover a wide range of substrates.

ATUM is UL-recognized at 110°C, 600 V.
