Thermoplastics vs. Thermosetting PolymersMatmatch
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. The terms thermoplastic and thermoset stand for how a material is or can be processed under a changed temperature 1 . The main physical difference is how they respond to high temperatures.
