Abstract:
Ultradisperse tetrafluoroethylene powder obtained by thermo-gas-dynamic method (FORUM TM material) was studied by derivatography, mass spectrometry, and differential scanning microcalorimetry. Thermal decomposition of FORUM and its thermophysical properties differ significantly from those of commercial PTFE. The temperature range of decomposition increased more than fourfold: 465-595oC for PTFE, and 70-550oC for FORUM. Thermal decomposition of FORUM gave a wide spectrum of molecular fragments with atomic weights from 31 up to 881. In the crystalline phase, there are no phase transitions characteristic of commercial PTFE samples; at the same time, the melting and transformation points in the amorphous part of the polymer are shifted.
