Materials and relevant technological applicationsĪ thermoplastic is a resin that is solid at room temperature but becomes plastic and soft upon heating, flowing due to crystal melting or by virtue of crossing the glass transition temperature (T g).

Processing of thermoplastics and thermosets.

Properties of thermoplastics and thermosets.

What crosslinking is and how it differentiates thermoplastics from thermosets.

While thermoplastics are like water, they can transition between ice and water with the application or removal of heat (reversible process).

On the other hand, thermoset polymers form a crosslinked structure during the curing process, preventing them from being melted and remoulded.Īs an analogy, think of thermosets like concrete, once they have set, they can never go back to the liquid form (irreversible process). Therefore, the curing process is reversible, which means that they can be remoulded and recycled. When heated to their melting point, thermoplastics soften into a liquid form. The main physical difference is how they respond to high temperatures. The terms thermoplastic and thermoset stand for how a material is or can be processed under a changed temperature. Thermoplastics and thermosetting polymers are types of plastic that undergo different production processes and yield a variety of properties depending on the constituent materials and production method.
