ATUM is a heat-shrinkable tubing with inner adhesive coating that seals and protects components against environmental influences, and is used for a variety of applications. Wire splices, breakouts, connector-to-cable transitions as well as electronic components can be sealed by ATUM to make them impervious to moisture. The excellent shrink capability compensates for differences in measurement, offers extra constructional possibilities and favours efficient storage.
