3M™ UHMW Polyethylene Tape 5421
3M™ UHMW Polyethylene Tape 5421 is a thinner version of 5423, coated with a rubber adhesive that bonds on contact. The UHMW-PE backing outlasts PTFE and other materials in sliding applications. In 3M testing, the tape showed no evidence of wear-through after 1,000 Taber Abrasion cycles using a CS-10 wheel and 1,000 g load when applied to an S-37 mounting sheet. This makes it well suited for tough impact-wear and sliding applications where lubrication is not possible because of contamination.
Applications include: Noise reduction between dissimilar parts, lining conveyor flat guide rails, tank and bin liners, discharge chutes, protecting aluminum sheets on stretch-forming presses, spray booth liners, and slick glide surfaces for drawers and cabinets.
- No wear-through after 1000 Taber Abrasion cycles
- Low water vapor transmission rate
- Low coefficient of friction, exceeded only by PTFE
- Liner-backed for easy fabricating and die-cutting
