Premium 6" x 18 yd UHMW polyethylene film tape with low friction backing for surface protection and noise reduction in industrial applications. Transparent, abrasion-resistant tape ideal for aerospace, automotive, and manufacturing industries.
3M™ UHMW Film Tape 5421 is a premium ultra-high molecular weight polyethylene tape designed for industrial surface protection and noise reduction applications. This transparent, abrasion-resistant tape features a unique low coefficient of friction that creates a "slip plane" effect between surfaces, allowing contact without wear. The tape measures 6 inches wide by 18 yards long with a total thickness of 6.7 mil and comes in a case of 2 rolls, making it ideal for high-volume industrial applications.
This general-purpose tape is specifically engineered for applications where lubrication is not possible due to contamination concerns. The rubber adhesive provides excellent initial tack for immediate bonding to material surfaces, while the UHMW-PE backing offers exceptional hardness and low surface energy. The tape is mounted on a 60# densified kraft paper liner with silicone treatment, making it perfect for die-cutting into custom lengths and shapes for specific application requirements.
The 3M™ UHMW Film Tape 5421 is widely used in aerospace, automotive, printing, and MRO industries for protecting plastic and metal chutes, guide rails, containers, conveyor systems, spray booth liners, tank and bin liners, drawer and cabinet slides, and aluminum sheet protection on stretch forming presses. Its superior abrasion resistance exceeds PTFE while maintaining a low coefficient of friction, ensuring long-lasting performance and successful solutions for tough impact wear or sliding applications. The tape operates effectively across a wide temperature range from -30°F to 225°F (-34°C to 107°C) and maintains an 18-month shelf life from the date of manufacture.
