Thermosets for Applications Requiring Heat Resistance

Applications Requiring Heat Resistance

One of the main benefits of using thermosets as a molding material for parts and components is the heat resistance and high temperature deflection properties that thermoset materials offer. Whereas thermoplastic molding materials such as a nylon or ABS can disfigure, melt, or carbonize; parts molded from a thermoset remain dimensionally stable, allowing the molded component or assembly to remain durable over the lifespan of a product even when exposed to elevated operating temperatures up to 400 or 500 degrees Fahrenheit. If your part or product assembly must withstand high operating temperatures and aggressive end-use elements, choosing a thermoset as your molding material may help keep your product assembly safe and functioning correctly.

Applications such as electrical housings and covers must remain dimensionally stable under high temperatures to protect internal components from being damaged. In automotive applications, some powertrain or transmission parts may also see high operating temperatures from the engine or transmission, which can even be magnified in the summer months. Additionally, electrical insulators and circuit breaker applications require an insulative material to limit heat dissipation into internal electrical components or cabling. Grill handles, oven/ range components, and bases and covers for small consumer cooking appliances all rely on thermosets to not only protect internal components but allow safe handling for the customer and product user. Outside of high-cost aerospace materials, thermoplastics do not offer the same level of heat resistance and temperature deflection properties as a molded thermoset will.
