Polystyrene melts at temperatures around 240°C (464°F). When heated beyond its melting point, it transitions from a solid to a viscous liquid state, allowing it to be molded or shaped. If exposed to even higher temperatures, it can decompose rather than just melt, releasing potentially harmful fumes.
