Premium UHMW polyethylene film tape with low friction and abrasion resistance for industrial surface protection. Transparent backing, rubber adhesive, ideal for noise reduction and wear prevention in aerospace, automotive, and manufacturing applications.
3M™ UHMW Film Tape 5421 is a premium ultra-high molecular weight polyethylene tape designed for industrial surface protection and wear resistance applications. This transparent, thin-caliper general-purpose polyethylene tape creates a unique "slip plane" effect that allows contact between surfaces without causing wear or damage. The tape features exceptional abrasion resistance, low coefficient of friction, and excellent chemical resistance, making it ideal for demanding industrial environments where lubrication is not possible due to contamination concerns.
The tape is specifically engineered to protect plastic and metal surfaces including chutes, guide rails, containers, drawer slides, and cabinet components from abrasion and impact wear. With a rubber adhesive that provides excellent initial tack and immediate bonding, the 5421 tape ensures secure and reliable adhesion to target surfaces. The translucent backing allows visibility while providing protective coverage, and the low-friction surface helps reduce squeaks, rattles, and other noises caused by vibration or movement. This product is mounted on a silicone-treated kraft paper liner, making it easy to die-cut into custom lengths and shapes for specific application requirements.
The extraordinary durability and versatility of UHMW-PE backing make this tape suitable for aerospace, automotive, printing, and MRO industries. Each case contains 9 rolls of tape, with each roll measuring 1 inch in width and 18 yards in length. The tape operates effectively across a wide temperature range from -30°F to 225°F, ensuring consistent performance in various industrial environments. This professional-grade tape meets rigorous ASTM specifications and is intended exclusively for industrial and occupational use.
