General
Colour	Orange

The Pliofine B-EX 2540 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 30 metres and is characterised by its orange colour, which enables easy identification and visual marking in the installation environment. 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 specifically designed for use in industrial and technical installations where a reliable and durable protective layer is required.

Applications

The Pliofine B-EX 2540 heat shrink tube is suitable for use in electrical installations, industrial automation, telecommunications, and building and plant control systems. It is frequently used to insulate cables, wiring, connectors and other electrical components to ensure their integrity and functionality. The orange colour supports visual differentiation in complex cabling systems, particularly in environments where clear marking of wiring is required according to standards or internal guidelines.

Functions and Features in Detail

The heat shrink tube has a shrink ratio of 2:1, meaning that it reduces to half its original outer diameter when thermally activated. This enables a tight, form-stable fit around the cables or wiring to be protected. The packaging contains 30 metres of heat shrink tube, which is sufficient for larger installations. The weight is 43.5 grams per metre, indicating a robust yet manageable material thickness. The orange colour is not only visually identifiable but can also serve as a marking for specific wiring functions or safety requirements.

Technical Explanation

The heat shrink tube is made of a thermoplastic material that shrinks when heated (e.g. with a hot air blower) and tightly conforms to the underlying cable. This process creates a dense, form-stable protective layer that resists mechanical stress, moisture and dust. The 2:1 shrink ratio allows flexible adaptation to various cable diameters, ensuring a tight fit after shrinking. The orange colour is durable and resistant to UV radiation and chemical influences, ensuring long-term stability of the marking.

Compatibility and Accessories

The Pliofine B-EX 2540 heat shrink tube is compatible with standard hot air blowers and other heat sources suitable for activating heat shrink tubes. It can be used with various cable types, including electrical wiring, data cables and connectors. Its use in combination with other protective materials, such as cable conduit or heat shrink tube sections, is possible as long as the respective technical requirements are met. The orange colour enables clear visual differentiation, especially in systems where colour coding is used to identify wiring functions or safety levels.

Installation and Mounting

Installation is carried out by sliding the heat shrink tube onto the cable or wiring to be protected. It is then heated using a hot air blower or another suitable heat source, causing it to shrink and form a tight, form-stable fit. The work surface should be clean and free of foreign objects to ensure optimal adhesion and shrinkage. The use of safety goggles and appropriate work clothing is recommended to ensure safety during the heating process.

Operational Advantages

The Pliofine B-EX 2540 heat shrink tube provides reliable mechanical and electrical insulation, extending the service life of the protected cables and wiring. The tight fit after shrinking prevents ingress of moisture, dust or other environmental influences. The orange colour facilitates visual identification and marking, making maintenance and fault diagnosis more efficient during operation. The packaging with 30 metres of length allows economical use in larger installations, eliminating the need for frequent reordering. The robust material thickness ensures long-term durability under industrial conditions.
