DOTshrink Heatshrink Tubing

The DOTshrink range of Heatshrink Tubing offer clients a convenient and cost-effective way of identifying cores and cables permanently, even in tough industrial environments.

Manufactured from flame retarded military grade Polyolefin, DOTshrink Heatshrink Tubing meets the requirements of a wide range of industrial and high technical standards and are also very versatile through excellent balance of chemical, electrical and mechanical properties.

The operating temperature range of DOTshrink Heatshrink Tubing is –55˚C to +135˚C, they are unaffected by water and offer excellent resistance to commonly encountered industrial chemicals.

DOTshrink Heatshrink Tubing is supplied on continuous spools of up to 30 metres and printed via our DOT-FCM / DOTshrink System thermal transfer printer. The pre-formatted, user-friendly DOTlabel Software allows information to be imported direct from Word and Excel, as well as having an
automatic sequencing feature.

The advantage of producing DOTshrink Heatshrink Tubing on a continuous spool is twofold. Firstly, it allows clients to change the length of each individual marker sleeve without changing the spool each time by simply selecting another template in DOTlabel Software, and more importantly, it’s more cost effective.
