Heat shrinkable tubing with a retraction rate of 2:1

What shrink ratio 2:1 Means ?

The essential characteristic of a heat shrinkable tubing is its ability to contract in diameter under the effect of heat. Thus, heat shrinkable tubing with an initial inner diameter of 25.4 mm and one shrink ratio of 2:1, its diameter to the minimum restrained take the value of 12.7 mm.

To complete this characteristic of Restricted 2:1, the industrialists propose ducts with complementary restricted ratios such as Restricted 1.2:1, Restricted 1.5:1, Restricted 3:1, Restricted 4:1 for fine walls, Restricted 6:1 for thick wall ducts with Restricted adhesive.

Example of a tubing with a shrink ratio of 2:1 : the heat shrinkable Single wall tubing model PF2-135

The thin-wall heat shrink tubing type PF2-135 shrink ratio 2:1 and a temperature of -55 °C to +135 °C, making it suitable for industrial environments subject to significant thermal variations. Its minimum restricted temperature above 70 °C facilitates fast and controlled implementation, while its 20 kV/mm dielectric rigidity guarantees reliable electrical insulation. Flexible, flame retarded and self-extinguishing (excluding transparent version), it is RoHS compliant and REACH certified and UL 224 125 °C, ensuring perfect compatibility with current normative requirements. Available in bars of 1 m or in coils of 15 to 150 m depending on the diameters (from 0.6 mm to 101.6 mm), or in dispenser box, this tubing Effectively covers elements of close diameters. It offers excellent dielectric, chemical and mechanical properties for electrical insulation, bare wire dressing, equipment, marking and identification. For applications requiring protection Waterproofa version with internal adhesive is recommended. All sizes, colours and packaging are accessible via the dedicated dimension guide.
