The friction wear properties and application of thermoplastic polyester elastomer and polyoxymethylene

Abstract

The experiment of injection molding, Dais-simulating test, morphological structure investigation (Scanning Electron Microscopy, SEM), X-ray photoelectron spectroscopy (XPS) were performed on mini-automobile spherical seat which was made of thermoplastic polyester elastomer (TPEE) and oiled polyoxymethylene (POM), respectively. The friction-wear properties between the frictionl pair of polymer spherical seat and metallic (iron) spherical pin were studied. The test results, indicate that the antifriction property of TPEE is superior to that of POM, while its surface chemical effect is inferior to that of POM.
