BAKING STYROFOAM TEST IN THE CONVECTION OVEN

 THE 130ºC TEMPERATURE TEST OF BAKING THE STYROFOAM  
   

 The test is to determine whether it is safe to bake Styrofoam in the convection oven. At the temperature of 130ºC, baking from 15 to 45 minute. Will it burn the Styrofoam and produce toxic fumes?

Cut a piece of foam approximately 40 mm x 40 mm x 20 mm thk. ( 1.5 inches x 1.5 inches x 3/4 inch thk.)

   
 To monitor the consistency of the oven temperature I placed a thermometer into the convection oven with the Styrofoam.
   
 Setting the oven temperature control to 130ºC and closed the oven door.
   
 After the full 15 minutes baking, at the temperature of 130ºC, the foam had shrunk an folded a little.
   
 Continue the process of baking another full 30 minutes at the same temperature of 130ºC.
   

 Observing it after the full 30 minutes of baking the Styrofoam had shrunk, no detection of any smell from the process of baking. you will notice that the temperature had risen to 140ºC.

Testing with full 45 minutes at 130º C does not burn the foam or does it give out toxic fumes or any nauseating smell.

THE 200ºC TEMPERATURE TEST OF BAKING THE STYROFOAM  
   
 Setting the temperature of baking the foam at 200ºC
   
   
 Baking at 200ºC for 15 minutes will give a plastic smell that is not as nauseating as burning smell of the polymer clay at the same baking temperature. No black smokes or toxic smell but the surface is slightly melted.
   

On observation the surface it was slight melted. From the size of 40 mm x 38 mm (1.5 inches x 1 3/8 inches) it had shrunk to a size of 15 mm x 13 mm ( 5/8 inch x 4/8 inch).

I do not recommend anyone to bake Styrofoam above the 130º C temperature.

This 200ºC temperature test is to prove that the Styrofoam will not burnt and without combustion there will not be any TOXIC FUMES.
