General
Colour	Green

The shrink tube Pliofine B-EX 2540 Box (2m) green 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, lines, and connections, particularly in environments where high resistance to external influences such as moisture, dust, or mechanical stress is required. 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 terms as the shrink ratio. This ensures a tight, form-stable fit around the protected lines, achieving reliable sealing and mechanical stabilization.

Applications

The shrink tube is intended for use in industrial and technical installations where permanent protection of electrical connections is necessary. It is particularly suitable for insulating cables in machines, systems, controls, and electrical installations. The green color serves as a visual identifier and can be used in certain applications to identify lines or protective conductors. The product is typically used in indoor and outdoor environments, where specific environmental conditions such as temperature, humidity, or chemical influences determine the selection of the appropriate shrink tube type.

Functions and Equipment in Detail

The Pliofine B-EX 2540 Box shrink tube is supplied in a length of 2 meters and packaged in a box. The packaging contains a single box that safely transports the product and protects it from damage. The green color of the tube is consistent along the entire length and serves both for optical visibility and for assignment to specific application areas. The shrink ratio of 2:1 allows flexible adaptation to various cable diameters, with the final fit achieved after heat treatment. The material composition ensures high mechanical strength and good resistance to environmental influences.

Technology Explained Simply

The shrink tube is made of a thermoplastic material that changes shape when heated. When heat is applied – for example, using a hot air blower or a specialized shrink tool – the tube contracts and tightly conforms to the underlying cable or connection. This process is called shrinking and results in a dense, form-stable sleeve that protects the underlying lines from mechanical stress, moisture, and contamination. The green color remains visible after shrinking and serves as a visual identifier. The shrink ratio of 2:1 means the tube shrinks to approximately half its original diameter, enabling a tight fit.

Compatibility and Accessories

The shrink tube is suitable for use with various cable types and electrical connections, especially in systems requiring high mechanical and electrical safety. It can be used in combination with other protective materials such as cable conduits, shrink tube sections, or insulating materials to create an additional protective layer. Use typically involves a heating device that provides the necessary heat to activate the shrinking process.

Installation and Mounting

Installation is performed by sliding the shrink tube over the area to be protected, followed by heat treatment. It is essential to ensure the tube is fully pulled over the area to be insulated to guarantee complete coverage. The heat source should be applied evenly and controlled to achieve uniform shrinking. After shrinking, the tube remains in its new, tighter form, forming a dense, form-stable sleeve. The green color remains visible and serves as an identifier.

A shrink tube is a flexible, thermoplastic material that changes shape when heated. The shrink ratio of 2:1 means the tube shrinks to approximately half its original diameter. The green color serves as a visual identifier and can be used in certain applications to identify lines or protective conductors. Insulation is achieved through the tight fit after shrinking, providing mechanical and electrical protection. The packaging consists of a box that safely transports the product.

Advantages in Operation

The shrink tube provides reliable, long-lasting protection for electrical connections. The tight fit after shrinking ensures high mechanical stability and effective sealing against moisture and contamination. The green color facilitates visual identification and assignment in complex installations. The simple handling and universal applicability in various technical environments make the shrink tube a practical tool for electrical and IT technicians. Use typically involves a heating device that provides the necessary heat to activate the shrinking process. The shrink ratio of 2:1 allows flexible adaptation to various cable diameters, enabling broad application possibilities.
