ABSTRACT:
This invention pertains to a hot plate and more specifically to an industrial hot plate for use in highly corrosive environments where chemicals of high acidity or high alkalinity are employed. An epoxy foam is utilized both to thermally isolate the heated surface from the base structure and to protect the heating element and the associated electrical circuit from damage from the active chemical agents that may be involved upon using the instant hot plate.
