What does TGGT stand for, and when should engineers specify it?

TGGT (Teflon Glass Glass Teflon) is rated for continuous use at 250℃.

Construction: It consists of a nickel-plated copper conductor, wrapped in PTFE tapes, covered by a fiberglass wrap, and finished with a PTFE jacket.

Application: It handles extreme heat and is highly resistant to chemical vapors, making it the preferred choice for commercial ovens, industrial heaters, and glass kilns. However, it lacks the dynamic flexibility of silicone.
