General
Colour	Blue

The Pliofine B-EX 3800 heat shrink tube from Ses-Sterling is a professional protective material for electrical and electronic wiring, cables, and connections. It is used in installation technology to protect cable bundles, connection points, or sensitive components from mechanical stress, moisture, dust, or contamination. The blue color of the tube serves as a visual identifier and facilitates recognition during installation. The packaging unit includes a spool with a length of 30 meters, enabling efficient and continuous processing in larger projects.

Applications

The heat shrink tube is suitable for use in electrical and IT installations as well as in industrial plant construction. It is frequently used for shielding cables, sealing plug connections, or mechanically stabilizing cable bundles. The blue color can serve as identification for specific cable types or systems, such as in building automation or the cabling of security systems. The product can be used both indoors and outdoors, with the material properties meeting requirements for weather resistance and mechanical durability.

Functions and Features in Detail

The Pliofine B-EX 3800 heat shrink tube has a shrink ratio of 2:1, meaning it reduces to half its original outer diameter when heated. This enables a tight, form-stable fit around the cable or connection to be protected. Shrinking is achieved by heat, typically using a hot air blower or a specialized shrink tool. The material composition ensures uniform and controlled deformation without cracks or irregularities. The blue color remains stable even after shrinking, providing clear visual differentiation.

Technology Explained Simply

The heat shrink tube is made of a thermoplastic polymer that changes shape when heated. The 2:1 shrink ratio means the tube shrinks to half its original diameter at a temperature of approximately 100 to 120 °C (depending on material composition). This creates a tight, form-stable covering around the cable or connection, protecting against mechanical stress, moisture, and dust. Shrinking occurs evenly along the entire length, resulting in a homogeneous protective layer. The material density and specific composition ensure high resistance to UV radiation, aging, and chemical influences.

Compatibility and Accessories

The heat shrink tube is universally applicable and can be used with various cable types, such as data cables, power cables, or control lines. It is particularly suitable for applications requiring durable, weather-resistant, and mechanically stable insulation. The use of a hot air blower or a specialized shrink tool is necessary to activate the shrinking process.

Installation and Mounting

Installation involves sliding the heat shrink tube over the cable or connection to be protected, followed by heating with a hot air blower. The temperature should be set so that the tube shrinks evenly without burning or cracking. Shrinking proceeds from one end to the other, with even heat distribution being important. Processing requires no special tools other than the heating device; the spool enables continuous processing without frequent switching.

Operational Advantages

The heat shrink tube provides a durable, form-stable protective layer that resists mechanical stress, moisture, and contamination. The blue color facilitates identification and marking during installation. Packaging in the form of a 30-meter spool enables efficient processing in larger projects. The material properties ensure high resistance to environmental influences, extending the service life of the protected connections. Processing is simple and requires no special tools other than a hot air blower.
