摘要：

The equilibrium melting temperature of polytetrafluoroethylene (PTFE), i. e. , the melting temperature of its most perfect crystals, is generally accepted to be 327 degree C. Using differential scanning calorimetry (DSC) at 10 degree C min** minus **1, the virgin (as-polymerized) PTFE exhibits a melting temperature (T//m) of about 342 plus or minus 2 degree C; the corresponding T//m of a sintered PTFE (melt-crystallized) being 328 plus or minus 2 degree C. This letter comments on the two melting temperatures of PTFE because the issue has not been addressed clearly in the literature. 5 Refs.
