why do we use thermosetting plastics to make plastic kettles?
thermosetting plastics can only be formed once from a liquid state, once they have cooled the polymer chains in the plastic form cross links, this in turn prevents the plastic from melting once heated after initial forming and cooling. if you did heat it a lot it would burn, not melt. so using it in a kettle is good because it wont rust, its electrically safe and it wont go soft and floppy when hot.
