Ses-Sterling 07390030005 Pliofine B-EX 2540 (1.22 m) orange shrink tube 2:1 content_copy

The shrink tube Pliofine B-EX 2540 (1.22m) orange from Ses-Sterling is a protective material specifically developed for use in electrical and electronic installations. It serves for mechanical and electrical insulation of cables, wires, and connections, particularly in environments where high requirements for protection class and resistance to external influences exist. The shrink tube is activated by heat, causing it to shrink to approximately half its original diameter – a ratio of 2:1, referred to in technical terminology as the shrink ratio. This enables a tight, form-stable fit around the protected conductors, ensuring reliable insulation and mechanical stabilization.

Applications

The shrink tube is intended for use in industrial, electrical, and electro-technical installations, particularly in areas where high mechanical load capacity and resistance to environmental influences are required. It is suitable for insulating cables, plug connections, solder joints, and other electrical connections. The orange color serves as a visual identifier and can be used in certain installations for identifying wires or systems. The length of 1.22 meters allows processing multiple connections from a single piece, minimizing material cutting and waste.

Functions and Features in Detail

The Pliofine B-EX 2540 shrink tube is characterized by its high thermal and mechanical load capacity. It is made from a special polymer material that shrinks when heated, forming a dense, form-stable sleeve around the underlying conductors. Shrinking occurs at temperatures starting from approximately 100 °C, with the exact temperature depending on the heat source used (e.g., heat gun, oven). The resulting fit ensures durable insulation and protects against mechanical damage, moisture, and contamination. The orange color is clearly visible and supports visual differentiation of wires in complex installations.

Technology Explained Simply

The shrink tube operates based on the thermoplastic properties of the material used. When heated, the material loses its shape stability and contracts due to internal tension. The shrink ratio of 2:1 means the tube shrinks to half its original diameter. This enables a tight fit around the conductors to be protected, creating a dense, watertight, and mechanically stable insulation. Shrinking occurs uniformly along the entire length, ensuring homogeneous coverage. Processing requires a heat source to provide the necessary temperature to activate the shrinking process.

Compatibility and Accessories

The shrink tube is suitable for use with various electrical and electronic components, particularly in installations requiring high standards for insulation and mechanical stability. It can be combined with cables, wires, plug connections, and solder joints. The use of shrink tubes is common in electrical and IT installations to ensure reliable and durable insulation.

Installation and Mounting

Installation is performed by sliding the shrink tube over the conductor or connection to be protected. Subsequently, a heat source is applied to initiate the shrinking process. The temperature must be chosen so that the tube shrinks evenly without damaging the underlying material. Processing requires controlled heat application to achieve an even and tight fit. After cooling, the shrink tube becomes firm and form-stable, ensuring durable insulation.

Operational Advantages

The shrink tube provides reliable and durable insulation that resists mechanical stress, moisture, and contamination. The tight fit ensures high electrical insulation and prevents ingress of foreign objects. The orange color facilitates visual identification in complex installations. The length of 1.22 meters allows processing multiple connections from a single piece, minimizing material cutting and waste.
