Made with fiberglass for durability and abrasion resistance, this electrical insulating tape also withstands high temperatures. The cloth can absorb electrical insulating varnishes.

Providing all-weather corrosion protection, this vinyl tape resists salt water, UV light, acids, and alkalies. It also resists impact and abrasion. Use it to wrap pipes and electrical conduit both above and below ground.

Create long-lasting seals around electrical connections, even in hot, cold, or wet conditions. Made of silicone, this tape stands up to chemicals, temperature changes, and UV rays, making it a good choice for insulating wiring and components in outdoor and other harsh environments. It is self-fusing, so it sticks to itself as you layer it for a secure seal that keeps moisture out. Also known as cold-shrink tape.

Attach EMI/RFI shields and gaskets to electronics housings—these rolls are loaded with conductive fibers. Also known as adhesive transfer tape, they have a thin film of pressure-sensitive glue on a peel-away liner. Unlike screws, they won’t leave gaps for EMI to get in. They’re also more conformable than tape with adhesive on both sides.

Backed with 3M VHB 4941 foam adhesive for strength, padding, and vibration resistance, this slippery tape bonds permanently to most materials.

Tested to meet ASTM E595, a standard used by NASA, this tape gives off almost no volatile emissions that could damage sensitive electronics, even in a vacuum. It’s more conformable than copper tape, so you can cover textured housings and round cables without leaving gaps for electromagnetic interference (EMI) to get in. When EMI makes contact, the conductive backing and adhesive convert it into heat and actively reflect it away. The conductivity of this tape also makes it great for electrical connections. Use it on surfaces that can’t be soldered.

Tested to meet ASTM E595, a standard used by NASA, this tape releases almost no volatile emissions that could damage sensitive electronics, even in a vacuum. Use it to repair and prototype circuit boards and shield components from EMI/RFI. With a copper backing and conductive adhesive, it’s useful for making electrical connections—current travels both along and through the tape. Unlike aluminum tape, it can be soldered. It’s also better at resisting chemicals.

Tacky adhesive on both sides of this tape grips and protects cable bundles. You can also wrap it around the end of hand tools for a nonslip grip.
