General
Colour	Yellow

The shrink tube Pliofine B-EX-03 3900 from Ses-Sterling is a professional protective material for cables and wiring in the field of electrical and IT installation. It is supplied on a reel with a length of 30 metres and is available in the colour yellow. The tube serves for mechanical and electrical insulation as well as protection against environmental influences such as dust, moisture or mechanical stress. It is specifically designed for use in industrial and technical installations, where reliable and durable shrinking is required.

Shrink tube
The shrink tube B-EX-03 3900 is a thermoplastic shrink tube that reduces its original length by a factor of three when heated to approximately 100 °C to 120 °C. This 3:1 shrink ratio enables a tight fit around cables, wiring or connection points, achieving a dense and stable covering. Shrinking is achieved by applying heat, either via a heat blower, heat gun or a special shrinking device. The yellow colour serves for visual identification and facilitates recognition in the installation environment.

Applications
The tube is suitable for use in electrical and electronic installations, particularly in areas where high mechanical load resistance and resistance to environmental influences are required. It is frequently used in industrial electrical installations, machine wiring, automation technology, and IT infrastructure. The yellow colour can be used to identify specific cable types or protection categories, with the exact meaning varying according to the operator’s internal guidelines.

Functions and features in detail
The shrink tube provides a reliable mechanical protective layer that protects cables from mechanical damage such as abrasion or pressure. It also prevents the ingress of dust, moisture or other particles, extending the service life of the enclosed wiring. Shrinking occurs evenly and without cracks, ensuring a dense and durable covering. Packaging in the form of a 30-metre reel enables efficient handling and processing, especially for longer installations.

Technology explained simply
The shrink tube is made of a thermoplastic material that changes shape when heated. Shrinking occurs by applying heat, causing the tube to shrink to approximately one-third of its original length. This results in a tight fit around the cable or connection to be protected. The yellow colour is not only visually identifiable but can also be used to categorise wiring, for example to distinguish between control and power cables. Shrinking occurs without additional adhesives, as the material itself forms an adhesive surface.

Compatibility and accessories
The shrink tube is compatible with standard cables and wiring used in electrical and IT installations. It can be processed using various heat sources such as heat blowers, heat guns or special shrinking devices. The use of accessories such as shrinking devices or heat sources is required to initiate shrinking.

Installation and mounting
Mounting is done by sliding the shrink tube over the cable or connection to be protected. Subsequently, the heat source, such as a heat blower or heat gun, is directed at the tube until it fully shrinks. The temperature should be between 100 °C and 120 °C to ensure even shrinking. After cooling, the tube remains in its new shape and permanently protects the cable. Processing requires no special tools other than the heat source.

Advantages in operation
The shrink tube provides a durable and reliable protective layer that extends the service life of cables. The yellow colour facilitates identification and marking in the installation environment. Shrinking occurs evenly and without cracks, achieving a dense covering. Packaging in a 30-metre reel enables efficient handling and processing, especially for longer installations. No additional adhesives are required, as the material adheres on its own.
