Question:

What is the origin of the names of thermoplastic polymers and thermosetting polymers?

Talk about your own understanding, why play these two names?

Answer:

Thermoplastic polymer also has some special cases, such as polytetrafluoroethylene, the decomposition temperature is lower than the viscosity flow temperature, it can not use the traditional thermoplastic method for processing, but only solid phase sintering and so on.
Plastic refers to the plasticity, as the name implies, the thermoplastic polymer is heated to a certain temperature after the molecular chain between the lifting of the tangled (or crystal melting), which becomes viscous material, in the role of external force can be deformed or flow . In contrast, thermosetting polymers undergo chemical cross-linking, onlookers are three-dimensional network of macromolecules, when heated will not enter the viscous flow, and thus can not be used thermoplastic processing, if you continue to heat, the thermosetting material Will occur degradation, oxidation, carbonation, until the combustion.
