3M 7010380325 Ptfe Glass Cloth Tape 5451 Brown 5.3 Mil

Product Description

The 3M 7010380325 is a PTFE-impregnated glass cloth tape supplied in a 0.5-inch-wide by 36-yard roll at 5.3 mil total thickness. It combines a woven fiberglass carrier with a PTFE coating and a silicone adhesive backing, producing a high-temperature release surface suited for heat-sealing equipment, process machinery, and conveying systems. The PTFE surface resists most chemicals, sheds moisture, and provides a slick, low-friction contact face. Silicone adhesive bonds the tape securely to heated tooling bars, platens, and channel surfaces while still allowing controlled removal during maintenance. Installers in packaging, electrical, HVAC duct fabrication, and industrial process environments rely on this tape for durable, repeatable release performance.

This tape is well suited for lining heat-seal bar assemblies where a hot wire or heated element contacts plastic film, film laminates, or foil pouches. It is also used on conveying chutes, troughs, and ducts to reduce friction and prevent material hang-up. Electricians and HVAC technicians apply it as a high-temperature insulating wrap and protective surface layer on duct components and process equipment exposed to elevated temperatures. The glass cloth carrier maintains dimensional stability under tension, making installation straightforward on both flat and slightly curved surfaces.

Key Features

• PTFE-coated glass cloth construction provides chemical resistance and a low-friction release surface
• Silicone adhesive rated for high-temperature service on heat-seal machines and process equipment
• 5.3 mil thickness balances conformability with puncture and abrasion resistance
• Low moisture absorption extends service life in humid or wash-down environments
• 0.5-inch width suits narrow heat-seal bars and tight channel applications
• 36-yard roll length reduces changeover frequency on active production or service runs

Compatibility

Designed as an OEM-style replacement and maintenance tape for heat-sealing machines, conveying chutes, troughs, ducts, and process equipment requiring a high-temperature PTFE release surface.

Installation Notes

Power down and allow all heated tooling, platens, or seal bars to cool to a safe handling temperature before removing worn tape and applying a new layer. Clean the substrate surface of adhesive residue and contaminants before application to ensure full bond contact. This tape is typically installed by electricians, HVAC technicians, or industrial maintenance mechanics following the equipment manufacturer's surface-preparation guidelines. Avoid stretching the tape during application, as this can cause edge lifting under thermal cycling.
