Masking Tape for Electronics

Use this tape to wrap and splice cables or to mask components while soldering. It dissipates heat and is an excellent electrical insulator.

Acrylic Plastic Adhesive—Tape with acrylic adhesive resists solvents and chemicals, so it’s often used in labs.

Silicone Adhesive—Tape with silicone adhesive withstands higher temperatures than tape with acrylic adhesive. It holds fast on engines, generators, and other machines that produce heat.

ASTM E595—Tape that meets ASTM E595, a standard set by NASA, will produce almost no volatile emissions, even in a high vacuum. It's a great choice for use around your most sensitive electronics.
