Numerical simulations of pulsed plasma thrusters with the MACH2 code have shown that the total ablated mass may be composed of ablation, late-time evaporation and liberation of Teflon polymers due to solid decomposition. The latter two contributions do not considerably add to the Impulse-bit thus degrading thruster performance. Calculations within a coaxial geometry have shown that placement of the Teflon bar in relation to the electrodes can significantly improve thrust efficiency. Transport coefficients have been upgraded to include magnetic field effects and a new two-temperature equation-of-state that includes molecular effects shows that it can provide considerable corrections to the equation-of-state model utilized in the aforementioned calculations.
