Molded Thermosets for Kitchen Appliance Products

Thermosets are used in products in a variety of industries. Electrical and automotive are two heavy users of molded thermoset components due to thermoset materials durability and protection against high temperatures and electrical current. Another industry that relies on the unique properties of thermoset molding materials is the home and consumer appliance market. Whether a product is a larger home appliance, or countertop cookware appliance, molded thermosets are used for elements and components touching high operating temperatures or requiring protection against electrical elements.

Utilizing thermoset materials into a component or product design offers safety and protection for the end users of the product. Many thermoset materials such as bulk molding compounds and phenolic molding compounds offer insulative properties, ensuring electrical current is not passed through the part and deterring electrical arc and track. Additionally, the insulative performance allows thermoset parts to be used to regulate outward temperatures of the assembly or product. Whereas a metallic or thermoplastic component may conduct electrical current or heat throughout a product or assembly, creating a safety hazard to internal components and for end-users handling the product, the insulative properties of thermosets allow for safe handling without the risk of being shocked or burned.

Housings, bases, and covers of appliance parts must protect internal components as well as allow safe-handling for users, even when internal heating elements reach upwards of 400F degrees and above. Many thermoset materials are UL rated for flammability resistance with a V0 or 5VA UL rating and will not disfigure or melt when exposed to elevated temperatures of 400-500F. Most engineered thermoplastics would degrade quickly or even melt under such elevated operating temperatures.
