Ovenware for microwave ovens which contain a composition comprising a susceptor and a thermoplastic or thermoset polymer are improved when the composition also has a thermal conductivity of about 0.7 W/m° K. or more. Heat generated by absorption of microwave radiation by the susceptor is more readily conducted to the food being cooked when the thermal conductivity of the composition is high, particularly when the part containing the susceptor is relatively thick. Also described are designs for various pieces of ovenware containing this composition.
A piece of ovenware suitable for heating and/or cooking food or drink, comprising, a composition which comprises a mixture of a thermoplastic polymer whose melting point and/or glass transition point is about 250° C. or more or a thermoset polymer whose softening point is about 250° C. or more, a heating effective amount of a microwave susceptor, provided that said composition has a thermal conductivity of about 0.70 W/m° K. or more when measured through a plane of said composition.
A piece of ovenware, comprising a composition which comprises a mixture of a thermoplastic polymer whose melting point and/or glass transition point is about 250° C. or more, or a thermoset polymer whose softening point is about 250° C. or more, and a heating effective amount of a microwave susceptor, wherein at least part of said composition is in the form of an insert.
A process for cooking in a microwave oven, comprising, contacting food or drink to be cooked and/or heated with a composition which comprises a mixture of a thermoplastic polymer whose melting point and/or glass transition point is about 250° C. or more or a thermoset polymer whose softening point is about 250° C. or more, a heating effective amount of a microwave susceptor, provided that said composition has a thermal conductivity of about 0.70 W/m° K. or more when measured through a plane of said composition, and exposing said food or drink in contact with said composition to microwave radiation.
