... of thermosets. For example, some of the thermoplastics, such as the ubiquitous polyethylene, have a maximum use temperature of only 49 °C (120 °F). Some, such as polycarbonates, can spontaneously crack at that temperature (such as on the dashboard of a car). Thermosets can be much more heat tolerant...
