WebHigh-temperature thermosetting polymer materials are often used in adhesives, sealants, and composite resins for applications that involve exposure to elevated temperatures. Such applications include integrated circuit housings, turbine brush seals, capacitors, airframes, radomes, and radiation-resistant structures. WebThermoset materials are generally stronger than thermoplastic materials due to this three dimensional network of bonds (cross-linking). Thermoset materials are also better suited to high-temperature applications up to the decomposition temperature. However, they are more brittle. Many thermosetting polymers are difficult to recycle.
