3M Adhesive Tape 5421

This transparent and highly durable adhesive tape reliably protects sensitive surfaces from wear and tear. Thanks to its low coefficient of friction, it allows surfaces in contact with each other to slide effortlessly—ideal for applications where lubricants must be avoided to prevent contamination.

The rubber-resin adhesive used ensures immediate and strong adhesion, facilitating the rapid bonding of different materials. The tape also helps minimize annoying noises such as squeaking or rattling that can result from friction or vibration.

Equipped with a removable release liner, the material can be easily cut into various shapes and lengths or further processed into die-cut parts. The protective liner is particularly practical for industrial processing and increases flexibility in application.

The 3M™ UHMW-PE Sliding Adhesive Tape 5421 is only 0.17 mm thick yet extremely robust. It offers excellent sliding properties while reliably protecting against mechanical stress. It is a thinner alternative to 3M™ 5423 Sliding Adhesive Tape, yet is equally well-suited for applications where durability and minimized friction are critical.

UHMW-PE adhesive tape is particularly common in industrial settings—whether for noise reduction or to protect metal or plastic components. The extremely wear-resistant and chemical-resistant material significantly extends the service life of the components in use. Its smooth surface is ideal for applications involving sliding contact, such as rollers or guides.

Typical applications:

• Slide rails and guideways in conveyor systems
• Protective linings in paint booths
• Linings for containers and tanks
• Slide rails in drawer systems
• Protective layers in cold drawing presses for aluminum

The technology behind the product:
This innovative adhesive tape is based on a carrier material made of UHMW polyethylene—a thermoplastic with an extremely high molecular weight. This gives the material a unique combination of hardness, chemical resistance, and very low surface energy. Compared to other materials such as PTFE, UHMW-PE exhibits significantly higher abrasion resistance, making it particularly durable.

Thanks to these special properties, 3M™ UHMW-PE Adhesive Tape 5421 is valued worldwide in many industries—including aerospace, automotive, printing, and general maintenance. Engineers and designers rely on the versatility and reliability of this tape when it comes to long-lasting lubricity and surface protection.
