Study on the Thermal Degradation Behaviors of the Sheath and Insulation Materials of FR-PVC Cables

Abstract:

The thermal and kinetic behaviors of the sheath and insulation material taken from the fire-retardant PVC cable have been investigated in the air atmosphere by using thermogravimetrical (TG) analysis method. The degrading activation energy (Ea) of the material were calculated through Kissinger and Flynn-Wall equations based on the TG and DTG curves. The results showed that there were three steps during the degrading process of the FR PVC cable sheath and insulation materials, and the degradation rate increased with the increase of the heating rate. The average activation energy of the sheath and insulation material obtained from Flynn-Wall equation were 118 kJ/mol and 134kJ/mol, respectively.
