General
Colour	Black

The Pliofine B-EX-03 1200 heat shrink tube from Ses-Sterling is a black-coloured, heat-shrinkable protective tube specifically developed for use in electrical and IT installations. It is used for mechanical and electrical insulation of cables, wires, and electrical connections, particularly in environments where high resistance to mechanical stress, moisture, or chemical influences is required. The packaging unit includes a spool with a length of 50 metres, with a weight of 22.33 grams per metre. The total packaging weight is 1.117 kg.

Heat shrink tube
The B-EX-03 1200 heat shrink tube is a thermoplastic shrink tube that shrinks to its original, smaller form when heated. This process enables a tight, form-stable covering of the wires or cables to be protected. The shrink ratio is 3:1, meaning the tube shrinks to one-third of its original outer diameter when heated. This ratio ensures a secure fit on various cable diameters and allows for flexible application in different installation scenarios.

Applications
The heat shrink tube is suitable for use in industrial, electrical, and IT installations, particularly in areas where high mechanical stability and insulation performance are required. It is frequently used for cable shielding, securing connections, marking wires, or protecting electrical components. The black colour provides a neutral visual appearance that integrates well into technical installations.

Functions and features in detail
The heat shrink tube provides a reliable mechanical protective layer that shields cables from mechanical damage such as abrasion, pressure, or impact. At the same time, it ensures electrical insulation, minimizing the risk of short circuits or leakage currents. The material composition is selected to offer high resistance to moisture and common chemical influences, making it suitable for use in damp or slightly aggressive environments.

Technology explained simply
When heated with a hot air blower or another suitable heat source, the tube shrinks evenly and conforms tightly to the underlying wire. The shrinking process occurs due to the thermoplastic properties of the material, which changes shape when heated and stabilizes in the new shape upon cooling. The black colouring is integral to the material and remains consistent even after shrinking, without fading or flaking off.

Compatibility and accessories
The heat shrink tube is compatible with standard cables and wires within the 3:1 shrink ratio. It can be processed using various heat sources such as hot air blowers or specialized shrink tools. There are no specific accessory items listed in the manufacturer’s catalogue as directly combinable.

Installation and mounting
Installation is carried out by sliding the heat shrink tube onto the wire or connection to be protected. It is then heated evenly using a heat source such as a hot air blower until it fully shrinks and forms a tight, form-stable covering. Processing requires no additional tools or adhesives. The processing temperature is within the typical range for thermoplastic shrink tubes, although no specific temperature is stated in the manufacturer’s datasheet.

Operational advantages
The heat shrink tube provides a durable, form-stable protective layer distinguished by high mechanical strength and electrical insulation performance. The even shrinking ensures a secure fit that does not require additional fastening means. The black colour allows for discreet integration into technical installations. Packaging in the form of a 50-metre spool offers an economical and practical handling solution for larger installations.
