Details
  • 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 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.

The effectiveness of 3M™ UHMW Film Tape 5421 lies in its Ultra-High Molecular Weight polyethylene (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 (Polytetrafluoroethylene) and increases as the molecular weight increases.

Suggested Applications

  • Conveyor guide rails and chutes
  • Spray booth liners
  • Tank and bin liners
  • Drawer and cabinet slides
  • Protecting aluminum sheets on stretch forming presses
