Polytetrafluoroethylene (PTFE AKA Teflon) is heat shrink tubing used when an application requires a high-temperature operation. Different. Heat-shrink tubing (or, commonly, heat shrink or heatshrink) is a shrinkable plastic tube used to insulate wires, providing abrasion resistance and environmental protection for stranded and solid wire conductors, connections, joints and terminals in electrical wiring. From automotive wiring harnesses to industrial control systems and consumer electronics, heat shrink tubing helps protect wires, terminals, and electrical connections from. If you need to insulate a damaged cable or install new wiring, it's always a good idea to have a few heat shrink tubes on hand. Thanks to their adaptable properties, they are highly versatile and easy to use. It insulates, protects, seals, and organizes wires — and in 2025, demand is growing for safer, smarter, and more sustainable options. Whether you're working on a wiring harness, marine-grade project, or.
