In low temperature experiments, resins have many applications as glues orthermal and electrical insulators. Cyanate ester resins (CEs) are ahigh-temperature compatible thermoset resin whose glass-transition temperature$T_g$ is ~300 $^\circ$C. Recently, we found that CEs also withstand lowtemperatures without microcracking by measuring $^4$He permeability. Here, wemeasured specific heat C, thermal conductivity \kappa, and magneticsusceptibility $\chi$ of different kinds of CEs in the wide temperature rangefrom room temperature to 0.5 K for C and 2 K for other two. The thermalproperties, C and \kappa, of different kinds of CEs are surprisingly coincidentwith each other. We discuss chemical structures and crystallinity of CEs andtheir blends based on the measured thermal properties. Compared to Stycast1266, a commonly-used epoxy resin in low temperature experiments, C of CEs islarger by a factor of 3 (<= 30 K), \kappa is lower by a factor of 4 (<= 10 K),indicating the small thermal diffusivity. The \chi values are as small asStycast 1266, indicative of their high purity. Our results show that cyanateesters are a new option for cryogenic resins with thermal insulative propertiesin/for low temperature experiments.
