The Pliofine B-EX 320 heat shrink tube from Ses-Sterling is a professional protective material for cables and wiring in electrical and IT installations. It is supplied on a reel with a length of 150 metres and is available in black. The heat shrink tube provides mechanical and electrical insulation as well as protection against environmental influences such as dust, moisture or mechanical stress. It is particularly suitable for use in industrial plants, in machine building or for wiring devices, where a reliable and durable protective layer is required.
Heat shrink tube is a thermoplastic material that changes its shape when heated to approximately 100 °C to 120 °C, shrinking to about 50 % of its original outer diameter. This 2:1 shrink ratio enables a tight fit around cables or wires, creating a dense and secure covering. The application of heat – for example, using a heat gun or a special shrinking device – is necessary to initiate the shrinking process. The black colour of the tube also provides visual identification and is resistant to UV radiation, making it suitable for outdoor use.
Applications include the insulation of cables, protective covering of connection points, covering of connections in electrical circuits, and marking of wiring. The heat shrink tube is frequently used in industrial electrical installations, during control system assembly, in automation technology, or for machine wiring. It protects against mechanical damage, such as scratches or pressure, and prevents the ingress of moisture or dust, thereby extending the service life of the covered wiring.
Functions and features in detail include high mechanical strength and resistance to chemical influences. The heat shrink tube is suitable for use in environments with increased insulation requirements. Packaging in the form of a 150-metre reel enables efficient handling and storage, especially for larger installations. The weight specification of 8.573 g per metre indicates the material density and supports planning for transport and installation processes.
Technology explained simply: The heat shrink tube is made of a thermoplastic polymer that changes shape when heated. Shrinking occurs through the application of heat, causing the tube to conform to the cable being protected and form a dense, shape-stable sleeve. The black colour is not only aesthetic but also functional, as it is UV-resistant and therefore suitable for long-term outdoor use. Processing is done using a heating device that provides the necessary temperature to activate the shrinking process.
Compatibility and accessories: The heat shrink tube is universally applicable and can be combined with various cable diameters, as long as the original inner diameter of the tube is larger than the cable diameter. Processing requires no special tools other than a heating device. There are no specific accessories mentioned in the manufacturer’s offering. The tube is applied directly onto the cable, with the length being cut to the required size as needed.
Installation and mounting are carried out by cutting the heat shrink tube to the desired length, placing it onto the cable, and then heating it with a heat gun or a special shrinking device. The temperature should be approximately 100 °C to 120 °C to ensure even shrinking. Installation is simple and does not require additional adhesives or fasteners. Processing is completed in a single step, with the shrinking time varying depending on length and ambient temperature.
The
operational advantages lie in easy handling, high reliability, and long service life. The heat shrink tube provides a durable protective layer that ensures mechanical and electrical insulation. Use in large quantities (150 m per reel) enables economical and efficient processing for larger projects. The black colour supports visual identification and is resistant to UV radiation, making it suitable for outdoor applications.
