UHMW Polyethylene Tape
3M5421 is a 6.7 mil. ultra-high molecular weight polyethylene film with a rubber adhesive which provides an excellent abrasion resistant surface. The liner makes tape ideal for fabricating or die-cutting into various lengths and shapes. UHMW polyethylene is a thermoplastic that has a unique combination of properties which make it ideal for many tough impact wear or sliding applications. Within its operational temperature range, UHMW polyethylene tape can provide the following advantages: (A) Outstanding abrasion resistance will outwear many types of PTFE and other materials in sliding applications. (B) Low coefficient of friction exceed only by the PTFE's. (C) Self-lubricating can often be used where lubrication is not possible because of contamination. (D) Sound damping high energy absorption capacity helps reduce noise levels in machinery and equipment. To obtain best tape performance, use within 12 months from date of manufacture and store under normal conditions of 60°F to 80°F and 40% to 60% relative humidity in the original carton.

The physical properties listed are typical values and are not to be considered as specifications. Our suggestions for use are based on tests we believe to be reliable. However, the purchaser must carry out their own tests to determine the suitability of the product for their internal use. Information is given in good faith, but without warranty.
It is essential, as with all pressure-sensitive tapes, that the surface to which the tape is applied be clean, dry and free of grease and oil.
Shelf life from date of manufacture is based on the product being stored at 70°F(21°C) / 50% relative humidity out of direct sunlight.
Specification compliance is dynamic and should only be used as a general guide. Always confirm that the tape you are interested in currently complies with all specification requirements. Please verify that the product number that you select is available in the proper size and color to meet your specification.
