The Pliofine SAM 32,0 (1.22m) shrink tube from Ses-Sterling is a black-coloured, thermoplastic shrink tube for use in electrical and IT installations. It is used for mechanical and electrical insulation of cables, wires and connections, particularly in applications where a tight, form-stable covering is required. The shrink tube is activated by heat and shrinks to approximately half its original diameter, creating a tight fit around the cable to be protected. The designation SAM 32,0 refers to the outer diameter of 32.0 mm before shrinking, with a shrink ratio of 2:1 – i.e. to approximately 16.0 mm after heat treatment. The length of the tube is 1.22 metres, providing sufficient material for multiple applications.

Applications

The shrink tube is suitable for use in industrial electrical installations, machine building, as well as in IT and communication technology. It is frequently used for insulating cable connections, shielding wires from mechanical stress, or for labelling cables. The black colour allows for discreet integration into technical systems and is also clearly visible during maintenance work. Due to its thermoplastic properties, it is suitable for applications requiring a permanent, form-stable covering.

Functions and Features in Detail

The Pliofine SAM 32,0 shrink tube is made from a thermoplastic material that shrinks when heated and then retains its shape. Shrinking is achieved by applying heat, for example using a hot air blower or a dedicated shrink tool. The 2:1 shrink ratio ensures a tight fit around the cable to be protected, resulting in a dense covering. The black colour is resistant to UV light and chemical influences, extending the service life of the tube in various environments. The length of 1.22 metres provides sufficient material for multiple applications without requiring additional cutting.

Technology Explained Simply

The shrink tube operates based on the thermoplastic properties of the material used. When heated above a certain temperature (typically from around 100 °C), the material begins to shrink and contracts to the specified diameter. This process is irreversible, so the tube retains its shape after heat treatment. The 2:1 shrink ratio means the tube shrinks to approximately half its original diameter. The black colour is not only aesthetic but also functional, as it is UV-resistant and thus suitable for outdoor use, provided no additional environmental conditions (such as high humidity or aggressive chemicals) are present.

Compatibility and Accessories

The shrink tube is compatible with standard cables and wires with a diameter up to 32.0 mm. After shrinking, it conforms to wires with a diameter of approximately 16.0 mm. It can be activated using various heat sources, including hot air blowers, dedicated shrink tools, or infrared heaters.

Installation and Mounting

Installation is performed by sliding the shrink tube over the cable or connection to be protected. It is then heated using a heat source (e.g. hot air blower), causing it to shrink and form a tight fit. The heat source should be moved evenly along the entire length of the tube to ensure uniform shrinking. After cooling, the tube retains its shape and provides permanent protection for the cable. The length of 1.22 metres allows multiple connections or cable sections to be covered with a single tube, minimising material waste and cutting.

Operational Advantages

The shrink tube provides a reliable, tight and form-stable covering that protects against mechanical stress, moisture and contamination. The thermoplastic property ensures the tube retains its shape after heat treatment, forming a durable protective layer. The black colour is UV-resistant and contributes to a long service life, especially in outdoor applications. The length of 1.22 metres provides sufficient material for multiple applications, increasing efficiency during installation. The product is easy to use and requires no special tools other than a heat source for activation.
