3M 7000029153 Ptfe Glass Cloth Tape 5451 Brown 2in X 36yd

Product Description

The 3M 7000029153 is a PTFE-impregnated glass cloth tape designed for high-temperature sealing, release, and insulation applications in industrial process environments. Sold as Tape 5451 in brown, it combines a woven glass cloth carrier with a PTFE coating and a silicone adhesive system. The result is a tape that delivers a slick, low-friction surface with strong tensile strength, puncture resistance, and abrasion resistance. At 5.3 mil total thickness, it holds up under repeated thermal cycling on heat-sealing equipment. PTFE chemistry also gives it broad chemical resistance and low moisture absorption, making it reliable in demanding production settings.

Tape 5451 is used primarily on heat seal bars, sealing jaws, and impulse wire sealing elements where a durable, easy-release surface is required. It is also applied to conveying chutes, troughs, ducts, and process guides to keep product flow smooth and reduce friction-related downtime. This tape is a common maintenance and build material for packaging equipment technicians, industrial maintenance professionals, and HVAC fabricators working with high-temperature ductwork assemblies. Each roll measures 2 inches wide by 36 yards long and is sold in a minimum quantity of 6 rolls per order.

Key Features

• PTFE-impregnated glass cloth construction provides a slick, non-stick release surface on heat sealing equipment
• Silicone adhesive bonds reliably to metal sealing bars and process equipment surfaces
• Resistant to most chemicals and exhibits low moisture absorption for consistent performance
• High tensile strength, puncture resistance, and abrasion resistance extend service life on moving or abrasive contact surfaces
• Suitable for conveying chutes, troughs, and ducts where low-friction surfaces reduce product hang-up
• 5.3 mil thickness provides durable insulation and protection on heat seal bars and hot-wire sealing elements

Compatibility

Designed for use on heat sealing machines, impulse sealers, conveying chutes, troughs, ducts, and process equipment requiring a high-temperature PTFE release surface.

Installation Notes

Installation should be performed by qualified maintenance technicians or equipment operators familiar with heat sealing systems. De-energize and allow all sealing equipment to cool fully before applying or replacing tape on heat seal bars or hot-wire elements. Surfaces should be clean, dry, and free of residue before application to ensure full adhesive contact. Follow equipment manufacturer guidelines and applicable facility safety procedures during tape replacement.
