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.
