Glass cloth tape pairs a rugged woven fiberglass backing with PTFE film or high temperature silicone adhesive, making it a go-to choice for electrical insulation, heat sealing, and demanding industrial repairs up to 500°F.
Glass cloth tape is the tape you reach for when the job throws heat, chemicals, and friction at you all at once. Woven from fiberglass yarns and coated with either a slick PTFE (Teflon) film or a high temperature silicone adhesive, it shrugs off conditions that would melt or peel ordinary tapes.
The PTFE film versions give you a smooth, low friction, non stick surface that is ideal for heat sealing bars, chute liners, gaskets, bearing surfaces, tabletop covers, and roll covers. The electrical grade glass cloth tapes, coated straight onto the fiberglass cloth with silicone adhesive, deliver excellent dielectric strength and are trusted for wire harnessing, motor and transformer insulation, and other electrical protection tasks.
Both styles handle continuous operating temperatures from -100°F to 500°F, resist abrasion and chemicals, and hold up to long term wear in aerospace, electrical, manufacturing, and construction settings. Whether you need a few inches for a quick fix or full rolls for a production line, this tape family is built to keep performing when the heat is on.
