Space radiation model uncertainties may have important influence on the evaluation of thermo physical properties of anti-electrostatics thermal control materials. The sources of space radiation model uncertainties are analyzed and the uncertainty factor is defined firstly, then the simulation test was performed on the surface resistivity of OSR in electron or proton radiation environments. After that, the influence of space radiation model uncertainties on the solar absorption of OSR was analyzed. As the increase of irradiation fluence, the influence of space radiation model uncertainties on the solar absorption increases firstly and then decrease utile it can be ignored. The influence of space radiation model uncertainties on surface resistivity of OSR increases with the uncertainty factor. When the uncertainty factor lower than 1, the error from space radiation model uncertainty to surface resistivity of OSR is positive, while the uncertainty factor larger than 1, the error is negative.
