Thermoset definition chemistry
Webb12 apr. 2024 · Thermoset plastics or thermosetting polymers are liquid resins at room temperature. These polymers harden upon heating or the addition of chemicals. Besides, thermoset plastics are typically produced with resin transfer molding (RTM) or reaction injection molding (RIM). WebbThermoset plastics are chemical resistant and can survive against both organic and inorganic acids. The density of thermosetting materials depends on their constituent components. These materials lose their elasticity upon heating and become brittle in nature. Thermosets can’t be reformed and recycled once they set their shape.
