General
Colour	Blue

The Pliofine B-EX 3200 heat shrink tube from Ses-Sterling is a protective material specifically developed for use in electrical and IT installations. Available in a length of 1.22 metres and in the colour blue, it is used for mechanical and electrical insulation of cables, wires, and connections. The heat shrink tube is activated by heat, causing it to shrink to approximately 50 % of its original outer diameter – a 2:1 ratio that ensures a tight fit and secure coverage. This property makes it particularly suitable for use in industrial environments where a reliable protective layer against moisture, dust, and mechanical stress is required.

Applications

The Pliofine B-EX 3200 heat shrink tube is commonly used in electrical installations, machine building, and automation technology. It protects cable connections, wire ends, or entire cable bundles from external influences. The blue colour serves as a visual identifier and facilitates easy recognition in cable management, especially in complex systems. It is typically used in both indoor and outdoor environments, with the material offering high resistance to environmental influences.

Functions and Features in Detail

The heat shrink tube features high mechanical strength and is resistant to moisture, dust, and minor mechanical stress. The 2:1 shrink ratio allows for precise adaptation to different cable diameters, creating a tight and shape-stable covering. The material composition ensures uniform shrinking without cracks or deformations, guaranteeing reliable insulation and protection. The blue colour is not only visually distinct but also serves as a marking for specific applications or systems.

Technology Explained Simply

A heat shrink tube functions through thermal activation: when heated – for example, with a hot air blower – the material contracts and tightly conforms to the underlying cable or connection. The 2:1 ratio means the tube shrinks to half its original diameter. This ensures a tight fit, providing mechanical stabilisation and electrical insulation. The material is designed to shrink without cracking or unevenness, enhancing the long-term stability of the connection.

Compatibility and Accessories

The Pliofine B-EX 3200 heat shrink tube is compatible with a wide range of cables and wires, particularly in electrical and IT technology. It can be activated using standard hot air blowers or other heat sources. It can be used in combination with other heat shrink tubes or insulating materials, provided material compatibility is ensured. The blue colour allows for clear visual differentiation, especially in systems with multiple cable bundles.

Installation and Mounting

Installation involves sliding the heat shrink tube over the cable or connection to be protected. It is then heated using a hot air blower or another suitable heat source until it fully shrinks. The temperature and duration of heating must be chosen to ensure uniform shrinking without overheating or material damage. Processing requires no additional tools or adhesives – the heat shrink tube secures itself through its thermal deformation.

Operational Advantages

The Pliofine B-EX 3200 heat shrink tube provides a reliable, durable protective layer that resists mechanical stress, moisture, and dust. The tight fit achieved by the 2:1 shrink ratio ensures a stable connection that remains secure even under vibration or movement. The blue colour simplifies identification and organisation in cable management. The simple installation without additional materials or tools makes it an efficient solution for professional installations.
