Abstract:
A thermocompensated susceptor laminate is described comprising a microwave transparent sheet, e. g. , paper, paperboard or plastic, having two layers thereon. One layer is a microwave interactive susceptor layer, e. g. , a dried dispersion comprising a film-forming vehicle together with microwave interactive particles such as metal, metal oxide, carbon or graphite that absorbs microwave energy to produce heat in a microwave oven. The second layer is an attenuator layer which includes electrically nonconductive thermocompensating particles of a mineral. One mineral attenuator is a hydrate containing bound water and having a dissociation temperature between about 100. degree. F. and 500. degree. F. , at which temperature the bound water is released therefrom to prevent overheating of the laminate.
