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.
Tape with acrylic adhesive resists solvents and chemicals, so it’s often used in labs. 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.
Tape with silicone adhesive withstands higher temperatures than tape with acrylic adhesive. It holds fast on engines, generators, and other machines that produce heat.

Antistatic Electrical Tape
A coating on this polyimide tape minimizes ESD (electrostatic discharge) when unwound from the roll and also during removal.
Use tape with acrylic adhesive where silicone contamination is a concern, such as surfaces to which you’re applying paint or other adhesives.
