Key Temperature Points for ABS:

• Glass Transition Temperature (Tg): Approximately 105°C to 110°C (221°F to 230°F). At this temperature range, ABS begins to soften and lose its rigid structure.
• Decomposition Temperature: ABS typically begins to decompose at temperatures above 240°C to 260°C (464°F to 500°F). Heating ABS beyond this point can lead to degradation and the release of potentially harmful fumes.

Since ABS is amorphous, it doesn’t have a clear melting point where it transitions from solid to liquid. Instead, it gradually softens over a range of temperatures, which is why it’s important to process ABS within a controlled temperature range during manufacturing processes like injection molding or 3D printing.
