However, when exposed to high temperatures, polystyrene can undergo a process called thermal decomposition, where it breaks down into smaller molecules and releases harmful chemicals.
Thermal Decomposition of Styrofoam
When Styrofoam is heated, it can undergo thermal decomposition, which is a process where the material breaks down into smaller molecules. This process can release a range of chemicals, including styrene, ethylene, and benzene. These chemicals can be harmful to human health and the environment, and can also contribute to the formation of toxic fumes.
Does Styrofoam Burn or Melt?
So, does Styrofoam burn or melt? The answer is that it can do both, depending on the temperature and conditions. When exposed to low temperatures, Styrofoam can melt and become soft and pliable. However, when exposed to high temperatures, Styrofoam can burn and release harmful chemicals.
Melting Point of Styrofoam
The melting point of Styrofoam is around 100°C to 120°C (212°F to 248°F), depending on the specific type and composition of the material. When heated to this temperature, Styrofoam can become soft and pliable, and can be molded into different shapes. However, if the temperature is increased further, Styrofoam can undergo thermal decomposition and release harmful chemicals.
Burning Point of Styrofoam
The burning point of Styrofoam is around 300°C to 400°C (572°F to 752°F), depending on the specific type and composition of the material. When heated to this temperature, Styrofoam can ignite and burn, releasing harmful chemicals and toxic fumes.
