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
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.
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.
