Due to the highly temperature-dependent physical behavior of thermosets, thermal analysis is an ideal technique for their identification and characterization.
This webinar discusses the most important thermal properties of thermosets and describes the thermal analysis techniques that can be used to measure them.
A thermoset is a polymer that undergoes a particular chemical reaction, known as curing, to form a permanent, crosslinked structure that cannot be melted or remolded to form a new shape. Thermosets are typically rigid, insoluble materials with high mechanical strength and temperature stability.
Examples include epoxy resins, phenolic resins, polyesters and polyurethanes.
Different thermal techniques can be used to determine the key properties of these materials:
A typical and important application is the measurement of the glass transition and curing reaction in epoxy resin materials.
