Industrial-grade UHMW polyethylene tape providing superior abrasion resistance, low friction surface protection, and noise reduction for metal and plastic surfaces across aerospace, automotive, and manufacturing applications.
3M™ UHMW Film Tape 5421 is a premium polyethylene-based protective tape designed for industrial applications requiring exceptional abrasion resistance and low friction properties. This transparent tape features ultra-high molecular weight polyethylene (UHMW-PE) backing that creates a highly effective "slip plane" between surfaces, allowing smooth movement while preventing wear and damage. The tape is 6.7 mil thick with dimensions of 3 inches wide by 18 yards long, packaged as 3 rolls per case, making it ideal for high-volume industrial operations.
The tape's unique combination of properties makes it exceptionally versatile for protecting metal and plastic surfaces in challenging environments. It features a rubber adhesive that provides immediate bonding and excellent initial tack, ensuring secure application to various substrates. The translucent backing offers visibility while protecting surfaces from abrasion, and its low coefficient of friction significantly reduces squeaks, rattles, and other noise issues caused by surface movement and vibration. This makes it particularly valuable in aerospace, automotive, printing, and maintenance repair operations (MRO) industries.
Manufactured with silicone-treated kraft paper liner, the tape is ideal for die-cutting and fabrication into custom lengths and shapes for specific applications. It operates effectively across a wide temperature range from -30°F to 225°F (-34°C to 107°C), providing reliable performance in diverse industrial environments. With an 18-month shelf life and compliance with ASTM D3330, ASTM D3652, and ASTM D3759 specifications, this industrial-grade tape delivers consistent, long-lasting performance for protecting guide rails, chutes, tank liners, drawer slides, and other high-wear surfaces.
