- Translucent, abrasion resistant backing helps protect surfaces from wear
- Low coefficient of friction for “slip plane” effect between surfaces
- Rubber adhesive provides good initial tack for immediate bonding to material surface
- Can help reduce squeaks, rattles and other noises that occur with movement
- Used in applications where lubrication is not possible because of contamination
- Liner makes it ideal for fabricating or die-cutting into various lengths and shapes
Used to protect surfaces from abrasion, 3M™ UHMW-PE Film Tape 5421 is a thin caliper general purpose polyethylene tape that creates a “slip plane” effect to allow contact without wear. This tape features a unique combination of properties that make it ideal for many tough impact wear or sliding applications. 3M™ UHMW-PE Film Tape 5421 is a thinner version of 3M™ UHMW-PE Film Tape 5423.
An Effective Solution for Many Noise and Vibration Problems
3M™ UHMW-PE Film Tape 5421 (PDF, 166.41 Kb) is often used in general industrial applications to help control squeaks and rattles due to vibration or wear of metal and plastic materials. This UHMW-PE (ultra-high molecular weight polyethylene) film tape provides good chemical resistance and excellent abrasion resistance that helps ensure a long wear life. 3M™ UHMW-PE Film Tape 5421 is mounted on a liner, making it easy to die-cut to meet the demands of specific applications. It is ideal for applications requiring a low coefficient of friction and the movement of parts and/or materials. This slick surface tape is primarily used in aerospace, automotive, printing and MRO industries.

The Science Behind Our Tape
The effectiveness of 3M™ UHMW-PE Film Tape 5421 lies in its Ultra-High Molecular Weight polyethylene (UHMW-PE) backing. UHMW-PE is a thermoplastic that has a unique combination of properties, such as exceptional hardness and low surface energy. The ultra-high molecular weight of this tape significantly reduces friction to create an effective solution for anti-stick and easy-release requirements. The abrasion resistance of UHMW-PE is greater than PTFE and increases as the molecular weight increases.
The extraordinary durability and versatility of UHMW-PE is used by designers and engineers in many industries worldwide. UHMW-PE based products offer a host of exceptional attributes that include high abrasion resistance, low coefficient of friction and one of the highest impact strength ratings of any thermoplastic. These attributes make them ideal for tough impact wear or sliding applications. The low coefficient of friction characteristic is surpassed only by PTFE; however, UHMW-PE tape has superior abrasion resistance. Our exceptional science and engineering of products provide long-lasting performance and successful solutions.
