Heavy-wall heat shrink tubing with 6:1 adhesive ratio from Ø3.2 to 119.4m m

Détails :

The heavy-wall heat shrink tubing Type PE6-A is a heavy-wall heat shrink tubing Of crosslinked polyolefin, fitted with an internal adhesive layer, and characterised by a shrink ratio excluding 6:1 standard. Under the effect of an adapted heat source, it can reduce its diameter to one-sixth of its initial size, allowing it to closely encompass elements of very different dimensions within the same sleeve. For example, only one heavy-wall heat shrink tubing Type PE6-A can cover a cable connector of large diameter and then retract enough to tighten the thinner part of the cable itself. During this process, the internal adhesive melts and adheres to the support, creating an integral seal around the connection. The obtained tubing ensures reliable electrical insulation (dielectric rigidity > 20 kV/mm) and forms a thick polymer shield solidary with the cable, preventing intrusion of water or contaminants. Once in place and cooled, the PE6-A offers leading mechanical protection, adding a layer resistant to impact, crushing and tension on the cable.

This high-restricted tubing is designed for the most demanding environments. It retains its properties in a wide temperature range (typically from -55 °C to +110 °C in use) without cracking or overly deforming. Its composition without halogens or heavy metals (such as cadmium) avoids the emission of corrosive fumes in the event of fire and meets existing environmental safety standards. In standard black for increased UV resistance, the heavy-wall heat shrink tubing Type PE6-A is insensitive to weather and chemical aggression, even in prolonged exposure. Whether underground, immersed in a technical look or in the sun, it maintains a lasting seal and protects the conductors from oxidation and premature aging.

The exceptional versatility of the heavy-wall heat shrink tubing Type PE6-A makes it a preferred choice for difficult professional applications. Its high reduction rate allows the standardization of a single tubing reference for cables or parts of very disparate diameters, simplifying the logistics of the yards. It can be found in the protection of electrical junctions of large or irregular shape: for example, to isolate and seal a bypass where several cables of different sections join together, or to coat the transition between a thick connector and a thinner cable. It excels in securing the splices of underground cables permanently subjected to soil moisture, preventing water penetration over the long term. Similarly, for external bonds exposed to UV, rain and temperature variations, the heavy-wall heat shrink tubing Type PE6-A provides seamless protection by avoiding weather-related degradation. In industry (mines, petrochemicals, telecommunications, etc.), it is used to make connections and repairs to cables that undergo vibration, corrosive products or mechanical stresses, guaranteeing maximum reliability of connections over time. In short, the heavy-wall heat shrink tubing Type PE6-A offers a high-end solution for the insulation, sealing and corrosion protection of cables in the harshest conditions, thanks to its adhesive that guarantees a hermetic closure and its incredible restraining capacity which adapts to almost all configurations.
