According to lattice QCD results, the two lightest glueballs are the scalar ($J^{PC}=0^{++}$) and the tensor ($J^{PC}=2^{++}$). From the well known dilaton potential that depends on a single dimentionful parameter, $\Lambda_G$, we study the scattering of two scalar and two tensor glueballs. From the scattering of two scalar glueballs we find that, using a proper unitarization scheme, a bound state, called glueballonium, can form if $\Lambda_G$ is small enough. The value of the phase shift obtained from this analysis can than be used in a Glueball Resonance Gas model, that describes the YM thermodynamics in the confined phase, to estimate the correction of the interactions to the pressure.
