Ses-Sterling 07470077010 Pliofine AD-UL-03 3900 (1.22m) black shrink tube 3:1 content_copy

The shrink tube Pliofine AD-UL-03 3900 from Ses-Sterling is a black-coloured, single-ended protective tube with a length of 1.22 metres. It is used for mechanical and electrical insulation of cables, wiring, and electrical connections in installations. The tube shrinks when heated, fitting tightly around the components to be protected and forming a dense, protective covering. It is specifically designed for use in electrical and IT installations, where reliable insulation and mechanical protection are required.

Shrink tube is the product type used here. This type of tube is made from a thermoplastic material that changes shape when heated to approximately 100 to 120 °C, shrinking to about one-third of its original outer diameter — a ratio referred to as 3:1. This shrink ratio allows for a tight fit on cables of varying thicknesses, achieving optimal mechanical stabilisation and electrical insulation. The black colour of the tube is not only aesthetic but also functional, as it is UV-resistant, making it suitable for outdoor use, provided environmental conditions allow.

Applications include protective covering of cables in electrical installations, shielding of connections in IT systems, and mechanical stabilisation of wiring in industrial facilities. The shrink tube is frequently used in the installation of network cables, connectors, sensors, and other electrical components where durable and resilient insulation is required. The length of 1.22 metres allows multiple connections to be processed from a single piece, minimising material waste and cutting.

Functions and features in detail include thermal shrinkability, activated by heat sources such as a hot air blower or heat lamp. The tube shrinks evenly and without cracking, forming a homogeneous and dense protective layer. The black colour is UV-resistant, enabling longer service life in outdoor environments, provided there is no direct, continuous sunlight exposure. The packaging unit includes a single piece, ready for immediate use.

Technology explained simply means that the shrink tube is made from a special polymer that changes shape when heated. This material is formulated to shrink to approximately one-third of its original diameter at a specific temperature (typically between 100 and 120 °C). This behaviour is enabled by the molecular structure of the material, which becomes elastic when heated and then transitions into a more stable, reduced form. The shrinkage occurs uniformly, avoiding gaps or uneven areas that could compromise the protective function.

Compatibility and accessories refer to use with various cable types and electrical components. The shrink tube is universally applicable and adapts to cable diameters within the 3:1 shrink ratio. It can be processed using hot air blowers, heat lamps, or other heat sources that ensure even heating.

Installation and mounting involve placing the tube over the area to be protected, followed by heating with an appropriate tool. Heat is distributed evenly to ensure complete and crack-free shrinkage. After cooling, the tube remains in its reduced form, protecting the underlying wiring. Installation requires no additional tools or adhesives, as the shrinkage itself creates a secure bond.

The operational advantages lie in easy handling, reliable protection, and long service life. The shrink tube provides a dense, mechanically stable, and electrically insulating covering that protects against mechanical damage, moisture, and contamination. The black colour supports UV resistance, expanding outdoor application possibilities. The length of 1.22 metres allows multiple connections to be processed from a single piece, increasing installation efficiency.
