QUADRIOS 1908CA065 lämpökutistesukka ilman liimaa musta 20 mm 2:1

Electricians and maintenance technicians rely on this non-adhesive heat shrink tubing to insulate and protect wire splices, terminations, and cable bundles in control cabinets and industrial installations. The black polyolefin sleeve slides over a 20 mm connection and, when heated, shrinks to a snug 10 mm, providing a durable, flame-retardant barrier without leaving sticky residue.

Key specifications

• Initial inner diameter: 20 mm; recovered inner diameter: 10 mm
• Shrink ratio: 2:1
• Material: Polyolefin (PO), non-adhesive
• Colour: Black
• Minimum shrink temperature: 70 °C
• Operating temperature range: -55 to 125 °C
• Dielectric strength: 15 kV/mm
• Tensile strength: 10.4 MPa; elongation at break: 200 %
• Flame retardant (self-extinguishing), UV resistant, halogen-free
• Recovered wall thickness: 0.85 mm
• Fluid resistance: Good to common fluids and solvents
• Standards: UL 224, CSA C22.2 No. 198.1, DIN VDE 0341 Part 900

Why choose it

Its 2:1 shrink ratio and flexible polyolefin construction make it easy to slide over connectors and irregular shapes, then shrink evenly for a tight, professional finish. The non-adhesive inner wall is ideal for applications where rework or inspection may be needed, and the self-extinguishing property adds safety in electrical enclosures.

Ideal use cases

• Insulating and protecting wire splices and terminations
• Bundling and strain relief for cable harnesses
• Marking and colour-coding cables in industrial panels
• Repairing damaged insulation on low-voltage wiring

Good to know

Heat with a hot air gun or heat tunnel until the tubing conforms tightly to the substrate. Avoid overheating beyond 125 °C to prevent degradation. The tubing is RoHS compliant and suitable for both indoor and outdoor use thanks to its UV resistance.
