The tape-scraper tribosystem of ATM (Auto Teller Machine) was used to study the wear properties of polymer tapes of PEN (polyethylene-2, 6-naphthalenedicarboxylate) and PI (polyimide) sliding against polymer scraper of POM (polyoxymethylene) in the clean air environment and in the simulated environment of sand dust with the natural sand from the desert. As main results, the mean wear rate of the PEN tape in the sand storm environment was about 500 times of that in the clean environment and the mean wear rate of the PI tape in the sand storm environment was about 1700 times of that in the clean environment. The PI tape exhibited higher abrasive resistance than the PEN tape. The bill substrate increased the abrasive resistance of polymer tapes. The micro wear mechanism examination showed the plastic flow and the broken of fibers for PEN tape and block fracture due to brittle nature for PI tape.
