The calculations of the transport and thermodynamic chemical equilibrium properties of polyethylen in range of temperaturs from 1000 K to 35000 K and densities from $\rho=10$ to 10 kg/m${}^3$ were carried out. The numerical set of tables for chemical equilibrium states of partially dissociated and ionized gas mixtures were prepared to fullfil a data base. The practical opportunities to adopt the table's data are of by using the diskets with the more detailed information about coefficients on it (lesser steps by $T$ and $\rho$). Some additional coefficients needed for users are also written there. There are data in the other variables ($P$ or $\rho$) and ($T$ or $h$) on the diskets.
