General
Colour	Orange

The Pliofine B-EX 640 heat shrink tube from Ses-Sterling is a professional protective material for electrical wires and cables in installation technology. It is supplied in the form of a spool with a length of 75 metres and is characterised by its orange colour, which enables easy visual identification in cabling areas. The heat shrink tube serves mechanical and electrical insulation as well as protection against environmental influences such as moisture, dust or mechanical stress. It is particularly suitable for use in industrial and technical installations where reliable and durable cable covering is required.

Heat shrink tube

The Pliofine B-EX 640 heat shrink tube is a thermoplastic shrink tube that reduces its original length by a ratio of 2:1 when heated to approximately 100 °C to 120 °C. This means that the tube shrinks to half its original outer diameter, creating a tight, dimensionally stable fit around the cable or wire. Shrinking occurs through heat treatment, during which the material structure contracts and forms a dense, protective sheath. The orange colour is not only visually identifiable but can also be used to mark specific wire functions or systems.

Applications

The heat shrink tube is designed for use in electrical and installation technology, particularly in areas where high mechanical load capacity and resistance to environmental influences are required. It is suitable for insulating cables, wires, plug connections and connection points, especially in industrial environments, machine construction, vehicle technology or in the field of building automation. Use typically occurs in indoor and outdoor installations, where the orange colour enables quick identification of wire functions.

Functions and equipment in detail

The heat shrink tube provides reliable mechanical and electrical insulation. It protects the underlying wires from mechanical damage, such as abrasion, pressure or bending stress. Additionally, it offers some protection against moisture and dust, thereby extending the service life of cable connections. Shrinking occurs evenly and without cracks, ensuring a dense and dimensionally stable covering. Packaging in the form of a 75-metre spool enables efficient and continuous processing, particularly in larger installations.

Technology explained simply

The heat shrink tube is made of a thermoplastic polymer that changes shape when heated. Heat is applied using a heat gun, heat tape or a flame (with caution). Once the material temperature reaches the shrinking range, the tube contracts and precisely conforms to the shape of the underlying cable. The 2:1 shrink ratio means the tube shrinks to half its original diameter. This ensures a tight fit, providing mechanical stability and high insulation effectiveness. The orange colour is an integral part of the material and remains even after shrinking.

Compatibility and accessories

The Pliofine B-EX 640 heat shrink tube is compatible with a wide range of cables and wires, particularly in electrical and installation technology. It can be processed using various heat sources, such as heat guns, heat tapes or controlled flames. The use of special heat shrinking tools can improve the quality of shrinking and reduce working time. There are no specific accessories mentioned in the manufacturer’s offer; however, heating devices and tools for heat shrinking are available in specialist trade.

Installation and mounting

Mounting is done by sliding the heat shrink tube over the cable or wire to be protected. Then, the heat source, such as a heat gun or flame, is evenly directed at the tube until it fully shrinks. The heat should be evenly distributed to avoid uneven shrinking or material damage. After shrinking, the tube remains in its new shape and protects the underlying wire. Processing requires no additional adhesives or fastening agents, as shrinking itself creates a secure connection.

Advantages in operation

The heat shrink tube provides a durable and reliable protective layer that extends the service life of cable connections. Mechanical stability protects against wear and damage, while electrical insulation increases safety. The orange colour facilitates identification and maintenance of wires. Packaging in the form of a 75-metre spool enables efficient processing in larger projects. Processing is simple and requires no additional materials, reducing mounting time and labour costs.
