This study demonstrates the efficiency of the spark plasma sintering (SPS) as a suitable technique to elaborate a dense polymer polytetrafluoroethylene (PTFE) which is difficult to sinter by conventional sintering methods e.g. hot pressing or hot iso-static pressing. Indeed, SPS is a very powerful technique not only to densify ceramics and dense metal, but also to prepare many kinds of material like alloys, polymers, composites. In this work we describe the experimental steps associated to the SPS process then the macroscopic and microscopic results such as the mechanical behavior, the thermal properties and the microstructural characteristics.
