Tubo termorretráctil CellPack 144392, negro, 100 cm de longitud

CellPack 144392 is a black heat shrink tubing supplied as a 100 cm length. It is intended for electrical insulation and mechanical protection of wire joints, cable splices and connectors where a flexible, heat-activated sleeve is required. The tubing features a thin wall construction without thermoplastic adhesive, is inscribable, stabilized against UV rays and resistant to various chemical agents. Its properties include high flexibility, superior electrical insulation performance and dimensional stability under thermal stress.

Advantages

The tubing provides reliable electrical insulation and mechanical protection while remaining thin-walled and flexible for confined spaces. It is resistant to chemical attack and cold flow, stabilized against UV exposure and free from paint-wetting inhibiting substances. The material is non-corrosive, infusible and self-extinguishing (except transparent variants), offering high tensile strength and good long-term performance in typical repair, maintenance and installation environments.

Suitable for

• Insulating wire joints and electrical splices
• Bundling and securing small cable groups
• Marking and identifying cable runs with inscriptions
• Providing corrosion and moisture protection for connectors
• DIY electrical repairs and maintenance tasks

Key specifications

• Material type: heat-shrinkable polymer (thin wall)
• Length: 100 cm
• Color: black
• Diameter before shrinking: 1.2 cm
• Adhesive: without thermoplastic adhesive
• Surface: inscribable for marking
• Chemical resistance: resistant to common chemical agents
• UV stability: stabilized against UV rays
• Flammability: self-extinguishing (except transparent versions)
• Mechanical: high tensile strength and high flexibility
• Thermal behavior: resistant to cold flow, thermally stable

How to use

Cut a suitable length of CellPack 144392 tubing to cover the joint or connector with some overlap at each end. Slide the tubing over the area to be insulated, ensuring it is centered over the splice or connector. Apply heat evenly using a heat gun, hot-air tool or other controlled heat source until the tubing contracts tightly around the components and conforms to their shape. Allow the tubing to cool and verify that it forms a continuous, snug sleeve without gaps.

Recommendations

For best results, use a regulated heat source and keep the heat source moving to avoid localized overheating. Ensure the operating temperature range and environmental exposure are suitable for a non-adhesive, thin-wall tubing. When marking is required, write on the tubing before shrinkage with a suitable ink or pencil compatible with inscribable surfaces.
