Properties of thermosoftening

WebThermosetting plastics and thermoplastics are both polymers, but they behave differently when exposed to heat. Thermoplastics can melt under heat after curing while thermoset … WebSuch polymers are called thermosoftening (meaning that they go soft when you heat them). The picture below shows the tangled polymer chains which have lined up and crystallised in the pink region. Some polymers do not form crystals. They soften when heated and harden when cooled down again. When cold, they are not crystalline but glassy.
