Heat shrink tube CellPack SRH2 56-16, black, 100 cm length

CellPack SRH2 56-16 is a black, halogen-free heat shrink tube with a 3:1 shrink ratio and a 100 cm length, designed for electrical insulation and mechanical protection of cables, connectors and joints. The medium-wall construction provides reliable sealing against moisture and pressure while delivering high tensile strength and stable electrical properties. The tube is suitable for use with or without adhesive and is available on a spool or in cut lengths for repair and installation tasks in electronics and electrical systems.

Advantages

The heat shrink tube offers superior mechanical protection and strain relief combined with resistance to chemical agents and UV stabilization. Its medium wall construction is inscribable and non-corrosive, resistant to cold flow and thermally stable, ensuring long-term dimensional and dielectric performance. Being halogen-free and free from paint-wetting inhibiting substances, it is suitable for environments that require reduced toxic emissions and reliable adhesion. The option of adhesive-lined or non-adhesive variants increases versatility for different sealing and bonding needs.

Suitable for

• Electrical insulation of single conductors and cable joints
• Protection and sealing of connectors, terminals and lynch points
• Repair and refurbishment of wiring harnesses in electronics and appliances
• Cable bundling and strain relief in installations and industrial equipment

Key specifications

• Material: halogen-free heat shrinkable polymer (medium wall)
• Shrink ratio: 3:1
• Length: 100 cm
• Colour: Black (UV stabilized)
• Mechanical: high tensile strength, resistant to cold flow
• Chemical: resistant to common chemical agents and non-corrosive
• Electrical: superior dielectric properties for insulation
• Surface: inscribable; free from paint-wetting inhibiting substances

How to use

Cut the CellPack SRH2 56-16 tube to the required length, slide it over the cable, connector or joint, and position it to fully cover the area requiring protection. Apply heat evenly using a hot air gun, heat tunnel or suitable heat source while maintaining a safe distance to avoid local overheating. The tube will contract to approximately one third of its original diameter; if using an adhesive-lined variant, the adhesive will melt and form an environmental seal as the tube shrinks. Allow the assembly to cool before handling.

Usage recommendations

For best results, match the tube inner diameter to the unshrunk cable or component size so that, after shrinking, the tube provides a snug mechanical fit and effective sealing. Use controlled, even heating and avoid open flames. Store in a cool, dry place away from direct sunlight to preserve material properties.
