3M | High Temperature Resistant Fireproof Electric Insulation Tape High Adhesion Waterproof

When I was renovating my home, I wasn't completely confident in the electrical connections left by the electrician, so I decided to buy some 3M 170 electrical tape to re-insulate them. Right from the start, I could feel the difference in quality—the tape's material is thick, and its stretch strength and flexibility are excellent. It feels smooth when wrapping wires, unlike cheaper tapes that snap easily or get sticky. The PVC material is soft and flexible, fitting snugly around the wire connections without loosening. The adhesive is just right, holding strong from the get-go and not shifting easily. The color is a standard black—solid and opaque, with good flame retardant properties. I tested it with a lighter, and it extinguished itself when removed from the flame, making it especially reassuring for home electrical use. 3M truly lives up to its reputation as a trusted brand; it definitely gives peace of mind!

The quality is really good, and using it feels reassuring.
