Self-amalgamating tape EMOS F52502 25 mm × 5 m, black

Self-amalgamating tape EMOS F52502 25 mm × 5 m in black is a single-sided, self-fusing insulating tape designed to bond to itself without using adhesives. The tape creates a seamless, flexible layer that isolates electrical connections, seals out moisture and protects against vibration and corrosion. With a 25 mm width and 5 m length, it is sized for common splicing, bundling and temporary repair tasks on wires, hoses and small connectors.

Advantages

The self-amalgamating structure provides a strong, uniform seal that does not leave sticky residue and remains flexible over a wide temperature range. It offers electrical insulation and water-resistant protection while conforming to irregular shapes and maintaining elasticity under mechanical stress. The tape is lightweight, easy to store and simple to apply by hand without tools.

Suitable for

• Insulating and repairing electrical splices and joints
• Sealing cable entries and connectors from moisture
• Temporary repairs on hoses, pipes and flexible tubing
• Bundling wires and organizing cable runs
• Protecting terminals and components from vibration and corrosion

Key specifications

• Color: black
• Width: 25 mm
• Length: 5 m
• Type: self-amalgamating / self-fusing insulating tape
• Material properties: flexible, elastic, water-resistant
• Application: electrical insulation, moisture sealing, mechanical protection

How to use

Ensure surfaces are clean, dry and free of oil or heavy contamination before application. Stretch the tape slightly while wrapping so that successive turns overlap and fuse to each other; typical overlap is 50% or more depending on required thickness. Start and finish the wrap beyond the damaged or exposed area to form a smooth, continuous seal. No adhesive is required—the tape bonds to itself over several minutes depending on temperature and tension.

Usage recommendations

For durable electrical insulation, wrap multiple layers until the desired thickness and dielectric strength are achieved. Avoid using the tape as a permanent mechanical splice for high-pressure systems; use it for sealing and temporary repairs, and inspect regularly if exposed to prolonged sunlight, oils or solvents. Store in a cool, dry place away from direct sunlight to preserve material properties.
