3M 7000048705 Ptfe Glass Cloth Tape 5453 Brown 12in X 36yd

Product Description

The 3M 7000048705 is a PTFE-impregnated glass cloth tape designated as 3M Tape 5453, measuring 12 inches wide by 36 yards long with an overall thickness of 8.2 mils. The glass cloth backing is fully saturated with PTFE (Polytetrafluoroethylene) and finished with a silicone pressure-sensitive adhesive. This construction delivers a non-stick, chemically resistant surface that performs reliably at elevated temperatures. The tape provides high tensile strength, puncture resistance, abrasion resistance, and low moisture absorption. It is commonly specified by maintenance technicians, production engineers, and industrial service professionals working on heat sealing and process equipment applications.

This tape is designed for use on heat sealing machines, conveying chutes, troughs, ducts, and related process equipment where a durable, high-temperature release surface is required. A typical application is lining the sealing bar beneath a hot wire that seals plastic film, where both release performance and thermal protection are critical. The 5453 designation indicates a thicker backing compared to the 3M Tape 5451 series, making it better suited for higher-wear surfaces that require additional mechanical durability. It is used in both light manufacturing and heavy industrial environments.

Key Features

• PTFE-impregnated glass cloth construction provides a slick, non-stick release surface at high temperatures
• 8.2 mil total thickness — thicker backing version of 3M Tape 5451 for increased wear resistance
• Silicone pressure-sensitive adhesive maintains bond under thermal cycling
• Resistant to most chemicals with low moisture absorption
• High tensile strength and puncture resistance for demanding process equipment surfaces
• Suitable for conveying chutes, troughs, ducts, and heat sealing bar applications

Compatibility

Designed as a replacement and protective lining tape for heat sealing machines, conveying equipment, and process machinery surfaces requiring a high-temperature PTFE release layer.

Installation Notes

Surface preparation is critical — clean and dry the substrate thoroughly before applying the tape to ensure full adhesive contact. Apply firm, even pressure across the entire tape surface to eliminate air pockets and promote adhesion. Power down and allow all equipment to reach a safe handling temperature before applying or replacing tape on heat sealing bars or heated surfaces. Trim edges cleanly with a sharp blade to reduce the risk of lifting under repeated thermal cycles.
