This polyester tape has a woven mesh edge that conducts electricity. Use it to shield cables and electronic components from EMI (electromagnetic interference). When wrapping objects, tape should overlap half of its width to achieve a highly effective four-ply shielding.

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

Tape with acrylic adhesive is the best at conforming to irregularly shaped surfaces. It’s also the best choice for use around sensitive electronics. Compliant with the NASA-set ASTM E595 standard, it gives off almost no volatile emissions that could damage electronics, even in a high vacuum. It’s made without halogens, so it won’t produce toxic smoke if it catches fire, either. This tape resists solvents, so it won’t come off during cleaning.

Use this tape to attach components to heat sinks and metal chassis walls in place of screws and other mechanical fasteners. It conducts heat away from sensitive electronics.

Aluminum foil tape conducts electricity. It also meets ASTM E595, a standard used by NASA, which means it produces almost no volatile emissions that could damage sensitive electronics, even in a high vacuum.

Tested to meet ASTM E595, a standard used by NASA, this tape seals gaps while releasing almost no volatile emissions that could damage sensitive electronics, even in a vacuum. The Tedlar backing resists chemicals and wear. And thanks to its acrylic adhesive, this tape will stay put—even when exposed to pulling forces and solvents.

Tested to meet ASTM E595, a standard used by NASA, this tape can mount sensitive electronics while releasing almost no volatile emissions that could damage them, even in a vacuum. Use it where temperatures fluctuate—its polyester backing keeps it from shrinking or stretching. And thanks to its acrylic adhesive, neither heat nor chemicals will cause it to peel off.
