Ses-Sterling 07390029008 Pliofine B-EX 1900 (1.22 m) violet shrink tube 2:1 content_copy

The Pliofine B-EX 1900 (1.22m) purple shrink tube from Ses-Sterling is a protective material specifically developed for use in explosive atmospheres. It serves for mechanical and electrical insulation of cables, lines, and electrical connections, particularly in installations that must comply with the requirements of the Explosion Protection Directive. The purple color identifies the shrink tube as a product for special operating conditions, and also serves for visual differentiation from other shrink tubes.

Applications
The shrink tube is designed for use in explosive atmospheres (Ex areas), particularly in the chemical industry, petrochemical industry, gas and oil industry, and other environments where flammable gases, vapors, or dusts may be present. It is used to protect cable connections, terminal clamps, or electrical components installed in these areas. The purple color serves as a visual indicator for the special approval and use in Ex areas.

Functions and Equipment in Detail
The 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 cables or lines to be protected. Shrinking occurs through heat, typically using a hot air blower or a specialized shrink tool. The purple color is not only visually identifiable but also serves as a marking for use in Ex areas. The length of the shrink tube is 1.22 meters, which is sufficient to cover longer cable sections or multiple connections.

Technology Explained Simply
The shrink tube is made of a thermoplastic material that changes shape and shrinks when heated. This process is triggered by the thermal energy applied to the material. Shrinking results in a tight, airtight, and mechanically stable covering of the underlying lines. The purple color is a visual feature indicating special approval for use in explosive atmospheres. The 2:1 shrink ratio allows flexible adaptation to different cable diameters, with the final fit remaining stable after shrinking.

Compatibility and Accessories
The shrink tube is designed for use with cables and lines in Ex areas. It is compatible with the requirements of the Explosion Protection Directive and is used in installations executed according to current explosion protection standards. Use requires suitable heating devices, such as hot air blowers, to initiate the shrinking process.

Installation and Mounting
Mounting is done by sliding the shrink tube over the cables or connections to be protected. It is then heated using a hot air blower or another suitable heating device until it shrinks and forms a tight fit. The purple color remains after shrinking and serves as a visual indicator. Installation requires no additional tools or materials, except the heating device to activate shrinking.

Advantages in Operation
The shrink tube provides reliable mechanical and electrical insulation, which remains durable even under difficult environmental conditions, such as in explosive atmospheres. The purple color allows for quick visual identification of the product as Ex-approved. The 2:1 shrink ratio ensures flexible adaptation to various cable diameters, providing broad applicability. The tight fit after shrinking protects against mechanical stress, moisture, and contamination, extending the service life of electrical connections.
