I have been experimenting with using reclaimed polystyrene as an art medium. I would like to shrink EPS for easier long-term storage by heating it to its glass transition point. However, I am worried about inadvertently releasing styrene vapor.
At what temperature will polystyrene begin releasing styrene vapor, and will it release large enough quantities to pose a threat to human and animal health?
Hello,
When polystyrene (PS) is heated, it begins to release styrene vapor. The glass transition point of PS is approximately 100°C (212°F) . However, it’s important to note that styrene is a storage hazard above 32°C (89.6°F), and when it decomposes due to heating, it releases acrid smoke and irritating fumes . While the quantities released during typical art-related processes may not pose an immediate threat to health, it’s advisable to work in a well-ventilated area and take necessary precautions.
