Forget about the melting point. You need to be looking at the heat deflection temperature. Most of the plastics usable in this temperature range are very expensive, Teflon (PTFE) is probably the cheapest. A high temperature epoxy (such as EpoxAcast 670 HT from Smooth-On) with the addition of glass fibers or powdered metal fillers to further increase the heat resistance might also work.
