## Long description

The EM Group thick-walled heat shrink tubing with adhesive is a high-performance solution designed for reliable electrical insulation and environmental protection. Featuring a shrink ratio of 40/12mm, this black tubing is engineered to provide a secure, tight fit around cables and joints. The integrated internal adhesive layer melts during the heating process, creating a moisture-proof and corrosion-resistant seal that safeguards connections in both indoor and outdoor applications.
Advantages
This heat shrink tubing offers exceptional mechanical strength and durability due to its thick-walled construction. The adhesive lining ensures that the tubing adheres firmly to the substrate, preventing slippage and providing an effective barrier against water, chemicals, and environmental contaminants. Its high shrink ratio allows for versatile use on various cable diameters, ensuring a professional finish and long-lasting protection for critical electrical infrastructure.
Suitable for
Sealing electrical cable joints and splices
Protecting cables from moisture and corrosion
Repairing damaged cable insulation
Industrial and residential electrical installations
Outdoor and underground cable protection
When it may not be suitable
This tubing is not intended for applications involving extreme heat sources that exceed the material's thermal rating or for use in environments with specific chemical exposure not covered by standard polyolefin specifications. It should not be used on cables where the diameter reduction exceeds the specified shrink ratio, as this may compromise the integrity of the seal.
Key specifications
Shrink ratio: 40/12mm
Material: Thick-walled polyolefin with internal adhesive
Color: Black
Length: 1 meter
Resistance: Moisture, corrosion, and mechanical stress
How to use
To apply the tubing, first ensure the cable surface is clean and free of debris. Cut the tubing to the required length, ensuring it overlaps the area to be protected. Slide the tubing over the connection and apply heat evenly using a heat gun or a suitable heating tool, starting from the center and moving towards the ends. Continue heating until the tubing has fully shrunk and the adhesive begins to flow slightly at the edges, indicating a proper seal.
What to consider before purchase
Verify the diameter of your cable to ensure it falls within the 40mm to 12mm range
Ensure you have a heat source capable of reaching the required activation temperature
Consider the environmental conditions where the cable will be installed
Usage recommendations
Always use appropriate safety gear, such as heat-resistant gloves, when working with heating tools. Ensure the workspace is well-ventilated during the shrinking process to avoid inhaling any fumes. Allow the tubing to cool completely before handling or applying mechanical stress to the connection.
