What type of electrical tape provides heat-stable insulation for high-temperature applications?

Glass cloth tape is specifically designed to provide heat-stable insulation suitable for high-temperature applications. Made from woven glass fibers, this type of tape can withstand elevated temperatures without degrading or losing its insulating properties. It is often used in applications where heat resistance is critical, such as in electrical insulation for components exposed to high temperatures or in furnace and exhaust applications.

In contrast, the other types of tape have different properties that make them unsuitable for high-temperature applications. Vinyl tape, for instance, is commonly used for insulation and protection, but it is not designed to handle extreme heat. Rubber tape has excellent insulation properties and is often used in electrical applications, but it too has limitations regarding temperature stability. Foam tape is typically used for sealing and cushioning rather than for electrical insulation, and it does not provide the heat resistance required in high-temperature environments.
