The purpose of this article is to investigate the effect of compaction pressure on the sintering of PTFE moldings. The major factor of this process are both compaction pressure and dwell time, which lead to high compactability of moldings. Bulk density of the moldings compacted at a lower pressure increases by sintering due to coalescence of particles by viscous flow. On the other hand, there is no change of the density by sintering in higher compacted moldings, since the coalescence of particles has been already finished in the pre-forming process and sintering does not eliminate inter-particle cavities. In this case, even if the moldings are sintered in shorter times nearly at the melting temperature, their bulk density reaches a constant value.
