When you eliminate polymers you eliminate most of the non-conductive materials however there are some that have been used with some success in the past such as molded asbestos which is fairly non-conductive and heat resistant but not very popular in most countries because of its pulmonary affection properties. Someone mentionned wood wich makes sense for its non-conductivity but not resistant enough and it is combustible (sparks can set it on fire).

As far as I know, they have always been made from polymers; beginning with bakelite plastic.
You might be able to get a ceramic to work, but it would have to be fired and then assembled, since the copper would not hold up to the firing.
Paper could work, perhaps being wound into a roll with the prongs of the plug sticking out.

Rubberized materials come to mind. You are trying to isolate stray voltage so that it is forced to follow the path on the ground pin. You don't want it jumping, and you don't want it being affected by heat and changing it's resistance value.

The only thing I can suggest is wood.
