This medium-walled heat shrink tube is characterized by particularly good resistance to mechanical damage. It is resistant to the effects of solvents, acids, and alkalis. The MA47 version is made with an internal coating of thermoplastic adhesive, which melts upon shrinking and provides additional protection against longitudinal water migration and the impact of external and atmospheric conditions. It is primarily used as a protective covering for cables and wires exposed to high loads and mechanical damage, both above and below ground; both for new cable installations in the ground and for repairs of existing installations.
