ATUM
High expansion ratio, adhesive-lined
heat-shrinkable tubing
ATUM tubing is radiation-crosslinked, tubing and the surface below, creating ATUM tubing is available with expansion
heat-shrinkable, and adhesive-lined to an excellent barrier to moisture ratios of both 3:1 and 4:1. These high
provide environmental sealing in a wide penetration. The adhesive bonds to a expansion ratios make it possible to
variety of electrical applications. The wide variety of plastics, rubbers, and repair cables without removing
product is typically used to seal metals, including PVC, polyethylene, connectors. Just a few sizes of ATUM
connector backshells and cable rubber, and aluminum. tubing cover a wide range of substrates.

Because the tubing and adhesive
ATUM has an internal adhesive coating are flexible, the moisture seal
