Abstract

Polytetrafluoroethylene (PTFE) exhibits excellent non-stick properties and a very low coefficient of friction under tribological stress, but it is incompatible with almost all other polymers. In the first part of this study, we presented the generation of the novel tribological material based on unsaturated oil, radiation-modified PTFE and Polyamide 66 (PA66). To get a better understanding of the chemical properties and chemical composition of the compounds, the PA66-PTFE-oil-cb (chemically bonded) compounds were examined by differential scanning calorimetry (DSC) and Fourier-transform infrared spectroscopy (FTIR). In this part, the mechanical properties of the compounds are compared with plain PA66 and PA66-MP1100-cb. The tribological investigation was carried out using the block-on-ring tribometer. It was detected that the mechanical properties of PA66-PTFE-oil-cb with 20 wt% PTFE-oil-cb only show slight differences compared to PA66, but the tribological properties of the compounds were significantly improved through chemical coupling between the three components.
