3M 7000050134 Ptfe Glass Cloth Tape 5451 Brown 1.5in X 36yd

Product Description

The 3M 7000050134 is a PTFE-impregnated glass cloth tape designed for high-temperature heat sealing and release surface applications. Sold as Tape 5451 in brown, it measures 1.5 inches wide by 36 yards long at a 5.6 mil total thickness. The glass cloth carrier is fully impregnated with PTFE and bonded with a silicone adhesive, delivering a slick, chemically resistant surface that withstands repeated heat cycles. High tensile strength, puncture resistance, and low moisture absorption make this tape a reliable choice for production environments where consistent, easy release is critical. HVAC fabricators, industrial maintenance technicians, and packaging equipment service personnel are the primary installers and users of this product.

Tape 5451 is suited for use on heat sealing machines and process equipment where a durable release surface is needed at the sealing bar or hot-wire station. It is also applied to conveying chutes, troughs, and ducts to reduce friction and keep materials moving smoothly. The PTFE surface protects against adhesion of plastic films, packaging materials, and other heat-sensitive substrates during continuous or batch production runs. Both light industrial and heavy production settings benefit from the combination of chemical resistance and thermal stability this tape provides.

Key Features

• PTFE-impregnated glass cloth construction provides a slick, non-stick release surface
• Silicone adhesive bonds reliably to metal sealing bars and equipment surfaces
• Resistant to most chemicals with low moisture absorption
• High tensile strength and puncture resistance for demanding production use
• 5.6 mil total thickness suits heat seal bar and conveying surface applications
• Suitable for protection and insulation on hot-wire sealing stations

Compatibility

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

Installation Notes

Surface preparation is critical before applying this tape — clean the sealing bar or equipment surface thoroughly to remove oils, residues, and debris. Power down and de-energize all heat sealing equipment before applying or replacing tape on sealing bars or hot-wire assemblies. Trim tape cleanly with a sharp blade and apply with firm, even pressure to eliminate air pockets. Follow the equipment manufacturer's guidelines and applicable facility safety procedures when servicing heat sealing or conveying equipment.
