Premium UHMW polyethylene film tape offering superior abrasion resistance and low friction for industrial surface protection, noise reduction, and wear prevention applications.
3M™ UHMW Film Tape 5421 is a premium ultra-high molecular weight polyethylene tape designed to protect surfaces from abrasion and wear in demanding industrial 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 a rubber adhesive that provides excellent initial tack for immediate bonding to material surfaces, making it ideal for applications where lubrication is not possible due to contamination concerns.
The 24 inch by 36 yard roll delivers exceptional versatility for industrial use across aerospace, automotive, printing, and MRO (Maintenance, Repair, and Operations) industries. With a total thickness of 6.7 mil and a polyethylene backing of 5 mil, this tape combines durability with flexibility. The low coefficient of friction characteristic makes it superior to many alternatives while maintaining exceptional abrasion resistance that exceeds PTFE performance. The translucent, abrasion-resistant backing helps protect surfaces from wear while the rubber adhesive ensures reliable bonding.
This UHMW-PE film tape is particularly effective for reducing squeaks, rattles, and other noises caused by vibration or movement between metal and plastic materials. The tape is 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. With an 18-month shelf life and compliance with ASTM D3330, ASTM D3652, and ASTM D3759 specifications, this tape delivers consistent performance and reliability for general industrial applications requiring surface protection and noise reduction.
