Heat-shrink tubing CellPack 145130, black, length 1 mm

CellPack 145130 is a black heat-shrink tubing designed to provide electrical insulation and mechanical protection for wires and cable joins. The tube has a stated length of 1 mm and a specified nominal diameter before shrinking of 3.81 cm; when heated it reduces in diameter to form a close-fitting protective layer. Intended for small-scale repairs, insulation of soldered joints and protection of cable ends in electronics and electrical installations, this heat-shrink tubing combines thin walls and high flexibility with stable electrical and mechanical characteristics.

Advantages

The product features a thin wall construction that enables a compact fit after shrinking while maintaining superior electrical properties and high tensile strength. It is halogen-free, non-corrosive and stabilized against UV rays, which supports long-term use in exposed environments. The tubing is inscribable for marking and identification, resistant to chemical agents and resistant to cold flow, offering reliable dimensional stability under thermal stress.

Suitable for

• Insulating soldered joints and wire connections
• Protecting cable ends and exposed conductors
• Bundling small groups of wires in electronic assemblies
• Marking and identification of wires using inscribable surface
• Providing corrosion protection in compact repair tasks

How to use

Select a tube segment of suitable diameter and slide it over the wire or joint to be insulated. Apply heat evenly using an appropriate heat source (heat gun, hot air tool or controlled flame at a safe distance) until the tubing contracts uniformly and forms a tight seal around the conductor or joint. Allow the tubing to cool undisturbed to complete the shrink process and ensure mechanical and insulating stability. Trim excess length if necessary, taking care not to damage the insulated area.

Recommendations

For consistent results, use a regulated hot air tool and keep the heat source moving to avoid overheating a single spot. Verify compatibility with the operating temperature and chemical environment of the application before installation. Use the inscribable surface for legible marking while the tubing is clean and dry.
