Frequently Asked Questions

Yes. The thermosetting silicone adhesive actually increases bond strength at elevated temperatures. Operating range is 32°F to 392°F, making it ideal for furnace controls, oven leads, and high-heat industrial applications where standard electrical tape degrades.

Absolutely. The glass cloth construction is conformable around irregular shapes and the pressure-sensitive adhesive adheres to connector pins, motor terminals, and control module wiring. It's rated for insulation up to 3,000V for safe high-voltage applications.

Yes. The 3/4" width and standard roll construction work with most industrial tape dispensers and core-based dispensing equipment. Confirm your dispenser accepts 3/4" tape widths and standard cores before ordering.

Glass cloth tape is flame-resistant, maintains adhesion at high temperatures, and resists edge tearing during application. PVC tape degrades above 212°F and loses grip. For packing lines near heating elements or high-temperature process equipment, glass cloth is the industry standard.
