1. Product Overview

3M™ PTFE Glass Cloth Tape 5453 is a premium brown woven glass cloth tape impregnated with PTFE (polytetrafluoroethylene), providing a non-stick, low-friction surface. It features a silicone adhesive that ensures high-temperature performance and long-term durability. The reinforced glass cloth backing offers superior tensile strength and resistance to tears, punctures, and abrasion, making it suitable for demanding industrial applications. The tape performs reliably across a wide temperature range (-73°C to 260°C) and exhibits excellent chemical resistance and low moisture absorption. It is designed to reduce build-up on machinery and provide long-lasting, anti-stick performance in high-temperature environments.


2. Applications

  • Heat sealing machines

  • Ironing and pressing equipment

  • High-temperature bundling

  • Mold release in composite bonding

  • Separation barrier for dissimilar parts

  • General industrial use where low friction or temporary chemical resistance is required
