Premium transparent UHMW polyethylene tape for industrial abrasion protection with low friction properties. Ideal for protecting surfaces, reducing noise and vibration in aerospace, automotive, and manufacturing applications.
3M™ UHMW Film Tape 5421 is a high-performance polyethylene-based protective tape designed for industrial applications requiring exceptional abrasion resistance and low friction properties. This transparent, thin-caliper tape creates a "slip plane" effect that allows contact between surfaces without wear, making it ideal for protecting plastic and metal chutes, guide rails, and containers. The tape features ultra-high molecular weight polyethylene (UHMW-PE) backing with a rubber adhesive that provides immediate bonding to material surfaces.
This versatile tape is engineered to solve multiple industrial challenges including squeaks, rattles, and vibration-related noise issues. With a thickness of 6.7 mil and a width of 5/8 inch (15.74 mm), it delivers superior performance in aerospace, automotive, printing, and maintenance/repair/operations (MRO) industries. The tape comes mounted on a 60# densified kraft silicone-treated paper liner, making it ideal for fabricating or die-cutting into various lengths and shapes for specific applications.
The UHMW-PE composition provides exceptional hardness, low surface energy, and outstanding chemical resistance while maintaining excellent durability. With an elongation at break of 440% and tensile strength of 30 lb/in (796 N/100mm), this tape withstands demanding industrial environments. The product is available in a case containing 12 rolls, each measuring 18 yards in length, providing substantial coverage for production and maintenance applications.
