The Pliofine B-EX 1270 heat shrink tube from Ses-Sterling is a professional protective material for electrical wires and cables in installations. It is supplied on a reel with a length of 50 metres and is available in black. The heat shrink tube serves for mechanical and electrical insulation as well as protection against environmental influences such as moisture, dust or mechanical stress. It is specifically designed for use in industrial and technical applications where a reliable and durable protective layer is required.

Heat shrink tube is a thermoplastic material that changes its original shape when heated to approximately 100 °C to 120 °C and shrinks to about 50 % of its original outer diameter – this corresponds to a shrink ratio of 2:1. This property enables a tight fit around cables or wires, creating a dense, protective sheath. The black colour of the tube is not only visually uniform but also functional, as it is UV-resistant and thus suitable for outdoor use, provided environmental conditions allow.

Functions and equipment in detail

The Pliofine B-EX 1270 heat shrink tube offers high mechanical strength and is resistant to a wide range of chemicals, including oils, greases and solvents. It is designed for temperatures from -55 °C to +125 °C, making it suitable for use in a broad range of environments, from cold warehouses to warm industrial process environments. The surface of the tube is smooth, ensuring easy installation and even shrinking. Packaging in the form of a 50-metre reel enables efficient handling and storage, especially for larger installations.

Technology explained simply

The shrinking process is carried out by heating the tube, with the heat source being either a hot air blower or a special heat shrink device. Upon reaching the shrink temperature, the tube contracts and tightly conforms to the underlying cable. The material remains stable and elastic after cooling, so it does not crack even under mechanical stress or movement of the wires. The thickness of the tube is approximately 0.2 mm according to the manufacturer, providing sufficient insulation and protective layer without impairing the flexibility of the wire.

Compatibility and accessories

The heat shrink tube is universally applicable and can be combined with various cable types, particularly electrical wires, data cables or sensor cables. It is especially suitable for use in electrical installations, automation technology and machine building. The packaging contains exclusively the 50-metre reel of heat shrink tube in black.

Installation and mounting

Mounting is done by sliding the tube onto the cable to be protected, ensuring sufficient length for the desired protection length. The tube is then heated using a hot air blower or a special heat shrink device until it shrinks and forms a tight sheath. Temperature must be controlled to avoid overheating and potential damage to the cable or the tube. Installation is quick and does not require additional adhesives or connections.

Advantages in operation

The Pliofine B-EX 1270 heat shrink tube provides a reliable, durable protective layer that extends the service life of cables and increases installation safety. High chemical resistance and temperature stability ensure long-term durability even under demanding conditions. Easy handling and packaging in a 50-metre reel simplify on-site work, especially for larger projects. The black colour is visually uniform and fits well into many technical environments.
