MICROWAVE-HEATABLE THERMOPLASTICS HAVING A SELECTED HEATING RATE

摘要

A method of formulating a microwave-heatable thermoplastic composition designed to have a selected heating rate. The method may include: selecting at least one of a microwave receptive additive, a microwave receptive additive particle size, and a concentration of the microwave receptive additive; selecting at least two inputs selected from the group consisting of a thermoplastic polymer composition, a microwave power, an electric field strength, a maximum allowable temperature of the thermoplastic polymer composition, a processing temperature of the thermoplastic polymer composition, and a thermal diffusivity of the thermoplastic polymer composition; and mixing a microwave receptive additive with a thermoplastic polymer to form the microwave-heatable thermoplastic composition having a selected heating rate based on the selecting at least one and the selecting at least two.
