Thermoset vs Thermoplastic (What’s the difference?) Examples of amorphous polymers are acrylonitrile butadiene styrene/acrylonitrile styrene acrylate (ABS/ASA), polycarbonate (PC), polymethyl methacrylate (PMMA), and copolyesters. This enables the opportunity to evaluate how different materials perform and to establish best-practice processing parameters.
