We present the Taylor expansion coefficients of the pressure in quark number chemical potential $\mu_0=\mu_B / 3=\mu_u=\mu_d$, for the strongly interacting matter as described by the PNJL model for two light degenerate flavours of quarks u and d. The expansion has been done upto eighth order in $\mu_0$, and the results are consistent with recent estimates from Lattice. We have further obtained the specific heat $C_V$, squared speed of sound $v_s^2$ and the conformal measure $\cC$.
