The Pliofine B-EX-03 3900 heat shrink tube from Ses-Sterling is a professional protective material for cables and wiring in the field of electrical and IT installation. It is supplied on a reel with a length of 30 metres and is available in the colour black. The tube serves for mechanical and electrical insulation as well as protection against environmental influences such as dust, moisture or mechanical stress. It is particularly suitable for use in industrial plants, in machine construction or for cabling in harsh environments, where a reliable and durable protective layer is required.

Heat shrink tube
The B-EX-03 3900 heat shrink tube is a thermoplastic shrink tube that shrinks to approximately one-third of its original outer diameter when heated to around 100 °C to 120 °C. This 3:1 shrink ratio enables a tight fit around cables or wires of varying thicknesses, achieving a secure and tight covering. Shrinking is achieved by applying heat, for example using a hot air blower or a special shrinking device. The material composition ensures high mechanical strength and good resistance to chemical influences.

Applications
The heat shrink tube is designed for use in electrical and IT installation, particularly in environments with increased requirements for protective function. It is frequently used for insulating cable ends, sealing connections or protecting cable bundles. Due to its robust nature, it is also suitable for use in industry, machine construction or automotive technology, where it must withstand mechanical stress and environmental influences. The black colour ensures discreet integration into technical installations.

Functions and features in detail
The heat shrink tube provides a reliable mechanical protective layer that protects cables from mechanical damage, such as abrasion or pressure. It also prevents the ingress of dust, moisture or other environmental influences, extending the service life of the enclosed wires. The shrinking property enables a form-stable covering that fits tightly around the wire to be protected. Packaging on a reel with 30 metres of length offers practical handling and is suitable for larger installations requiring continuous processing.

Technology explained simply
The heat shrink tube is made of a thermoplastic material that changes shape when heated. The heat energy triggers a molecular reorganisation, causing the tube to shrink and form a dense, form-stable sleeve around the cable. The 3:1 shrink ratio means the tube shrinks to one-third of its original outer diameter, allowing flexible adaptation to different cable diameters. The shrinking temperature is in the range of approximately 100 °C to 120 °C, which can be achieved using common hot air blowers or special shrinking devices. The material composition ensures high resistance to mechanical stress and chemical influences.

Compatibility and accessories
The heat shrink tube is universally applicable and compatible with a wide range of cables and wires in the electrical and IT sector. It can be processed using common shrinking devices or hot air blowers. The use of heat shrink tube in combination with other protective materials, such as cable conduit or shrink tubes, is possible, provided material compatibility is ensured. Packaging on a reel with 30 metres of length enables efficient processing for larger projects.

Installation and mounting
Mounting is done by sliding the heat shrink tube onto the cable or wire to be protected. The tube is then heated using a hot air blower or a special shrinking device until it shrinks to approximately one-third of its original outer diameter. Care should be taken to ensure even heat distribution to guarantee uniform shrinking. Processing typically occurs at temperatures between 100 °C and 120 °C. Packaging on a reel facilitates handling and enables continuous processing for longer installations.

Advantages in operation
The heat shrink tube provides a reliable and durable protective layer that protects cables from mechanical damage, dust, moisture and chemical influences. The form-stable covering ensures a secure and tight connection that remains intact even under harsh operating conditions. Packaging on a reel with 30 metres of length enables efficient processing for larger installations. The black colour ensures discreet integration into technical systems. Processing is simple and requires no special tools other than a hot air blower or shrinking device.
