More conformable than copper foil electrical tape, this tape bonds to textured electronic housings, round cables, and other curved and irregular surfaces. Since it doesn’t leave gaps, it’s a great shield against electromagnetic interference (EMI). Its conductive backing and adhesive convert EMI into heat and reflect it away from your electronics. Use this tape on surfaces that can’t be soldered.

This tape reflects intense heat to protect sensitive components.

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.

Stick this flexible tape to the back of welding seams to contain spatter and prevent oxygen, water vapor, and other gases from weakening the weld. Also known as back purge tape, it’s used for welding flat sheets, large tanks, and other applications where filling the space behind the seam with purge gas is difficult or expensive. Form the fiberglass spine into a small ridge over the weld joint, then press the adhesive foil down on each side. Compatible with MIG, TIG, and stick welding.
