Overview
The effectiveness of 3M™ UHMW film tape 5421 lies in its UHMW backing. UHMW 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 this friction reducing tape is greater than PTFE and increases as the molecular weight increases. 3M™ UHMW 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 makes it ideal for many tough impact applications. 3M™ UHMW film tape 5421 is a thinner version of 3M™ UHMW film tape 5423.
Features & Benefits
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
