The Influence of Alumag Nanopowders on Polytetrafluoroethylene Properties and Structure

Abstract

The results of investigation of influence of synthetic fibrous nanopowders of alumag (mix of aluminum and magnesium oxides) on polytetrafluoroethylene structure and properties are presented in this paper. Antifrictional material with the high level of deformation and strength characteristics (at the maintenance of filler to 5 mas. %) is received by modification of PTFE with alumag. It is shown that particles of alumag act as the centers of crystallization. In case of increase in content of the nanomodifier the sizes of sferolits decrease that leads to increase of density of packaging and increase of wear resistance of the material.
