3M UHMW-PE film tape 5421 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. This slick surface tape is primarily used in aerospace, automotive, printing and MRO industries. - 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. Translucent, abrasion resistant backing helps protect surfaces from wear.
