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. breakouts and to repair damaged cable. ATUM is UL-recognized at 110C, 600 V. Because the tubing and adhesive ATUM has an internal adhesive coating are flexible, the moisture seal that, when heated, melts and flows to withstands bending of the substrate. form a positive environmental seal. This flexibility makes ATUM tubing The coating adheres to the outer ideal for cable repair.
