Our PTFE Glass Cloth Tape for High-Heat Projects Apply PTFE glass cloth tape for your heat sealing equipment or any project that requires high-heat resistance and easy release. Our PTFE glass cloth tape features industrial Teflon for protection and insulation and woven glass cloth for reinforcement that resists tearing. This tape has longevity in most projects but also features anti-stick properties for quick removal without residue or damage. Built to Last As Long As You Need It. The PTFE glass cloth tape roll is 1/2 inch wide and 36 yards long, while the film thickness is only 3 millimeters once peeled. Made from industrial Teflon, polytetrafluoroethylene, or PTFE, glass cloth and silicone adhesive, this tape is built to withstand high temperatures and abrasion without becoming damaged or peeling. This tape is insulated by the silicone adhesive, which also provides easy release from surfaces even after exposed to high heat. The woven glass cloth prevents tearing, puncturing or any splitting during use.
