Heavy-wall heat shrink tubing Ø92/26mm length 1m

Détails :

Made of polyolethin high thickness crosslinked, heat shrinkable tubing PE4 (restriction factor 4:1) ensures excellent driver insulation and enhanced physical protection. Without internal adhesive, it retracts under the effect of heat (restricted temperature > 110 °C) to closely marry the cables or components, forming a uniformly tight protective envelope around them. Its heavy wall gives high dielectric rigidity (~17 kV/mm) ensuring the electrical insulation required in low voltage, while improving mechanical strength against shocks and crushing. Polyole materialthin, once crosslinked, has thermal stability ranging from about -55 °C to +110 °C in continuous operation, without hardening or cracking.

Designed without halogen and generally offered in black (UV-treated), the tubing PE4 offers excellent resistance to external aggression : It tolerates weather, UV rays, abrasion, corrosion and many common chemicals. These properties provide lasting protection for cables subject to demanding conditions, whether on outdoor installations, industrial areas or underground ducts. Even without adhesive, the tubing remains in place without slipping and does not tear once retracted, ensuring constant long-term protection.

Thanks to its large wall thickness up to 4.8 mm, the PE4 provides solid mechanical protection while maintaining some flexibility of use. It is particularly suitable for the repair of ducts and maintenance of worn cables : by slipping the tubing on the damaged section and then by heating it, we recreate an external insulation almost as reliable as the original. This sleeve thick is commonly used to isolate splices and ends of low voltage cables, boost electrical beams and protect connections from wear and corrosion. It should be noted that the absence of adhesives rather than direct immersion applications – in a very humid or submerged environment, it can be combined with a mastic or opt for the adhesive version in order to achieve a perfect seal.
