High temperature thermoset polymers
Did you know?
WebThermoset plastics, also called thermosetting resin or thermosetting polymers, are typically liquid at room temperature and then harden once heated or with a chemical addition. … WebThe name high temperature plastics is in use due to their continuous service temperature (CST), which is always higher than 150 °C by definition (although this is not their only feature, as it can be seen above). The term "polymers" is often used instead of "plastics" because both terms are used as synonyms in the field of engineering.
