General
Colour	Red

The shrink tube Pliofine B-EX 3200 (1.22m) red from Ses-Sterling is a protective material specifically developed for use in electrical and electronic installations. It serves for mechanical and electrical insulation of cables, wires, and connections, particularly in environments where high requirements for protection class and resistance to external influences exist. The shrink tube is activated by heat, causing it to shrink to approximately 50% of its original outer diameter – a ratio referred to as 2:1 shrink ratio. This ratio enables a secure, tight, and form-stable covering of the components to be protected, thereby achieving reliable insulation and mechanical stabilization.

Applications

The shrink tube Pliofine B-EX 3200 is designed for use in industrial and technical installations where high mechanical load capacity and chemical resistance are required. It is particularly suitable for protecting cables and wires in electrical installations, automation technology, and manufacturing technology. The red colour of the tube serves as a visual identifier and can be used in installations to identify specific wire functions or categories. The length of 1.22 metres allows for flexible application, with the tube supplied as a single piece to cover longer connections or multiple points in one work step.

Functions and Features in Detail

The shrink tube features high mechanical strength and is resistant to mechanical stresses such as impact, friction, and pressure. It protects the underlying wires from external influences such as moisture, dust, chemical substances, and mechanical damage. The 2:1 shrink ratio ensures that the tube shrinks evenly and tightly around the wire to be protected, creating an airtight and watertight covering. This is particularly important in environments where insulation must be protected against moisture or contamination.

Technology Explained Simply

When heated with a hot air blower or another suitable heat source, the shrink tube contracts and conforms closely to the underlying wire. The heat activates the thermoplastic properties of the material, causing it to harden and form a durable, form-stable sleeve. The red colouring is not only visually identifiable but can also be used for categorizing wires in complex installations. The material composition is chosen to provide high heat resistance and chemical resistance, making the shrink tube suitable for use in demanding environments.

Compatibility and Accessories

The shrink tube is universally applicable and can be combined with various cable types, wires, and electrical connections, as long as their diameter falls within the shrink range. It is not specifically designed for a particular brand or product series, but serves as a general protective material. Processing involves manually placing the tube onto the wire to be protected, followed by applying heat until the shrinking process is complete.

Installation and Mounting

Installation is carried out by simply sliding the shrink tube over the wire or connection to be protected. Subsequently, heat is applied evenly and controlled to ensure uniform shrinking. It is important not to apply heat too intensely or for too long to avoid damaging the material. The length of 1.22 metres allows coverage of multiple connections or longer sections in a single work step.

Operational Advantages

The shrink tube provides reliable, durable, and form-stable insulation, extending the service life of the protected wires. The red colour facilitates identification and maintenance in complex installations. High mechanical strength and chemical resistance ensure long-term durability even under demanding operating conditions. The simple handling and universal applicability make the shrink tube a practical tool in the electrical and installation industry.
