Styrofoam will start softening at 212 degrees F and melting at 464 degrees F but that doesnt mean you should use it in the oven regardless of the temperature. 210-249 C 410-480 F Typical Injection Molding Temperature.
However styrofoam containers will start softening way before the heat reaches this degree.
What temp does styrofoam melt. At What Temperature Does Styrofoam Melt. 464 FAs we have already mentioned styrofoam is expanded polystyrene beads. The temperature at which these beads melt is 464 F 240 C.
However styrofoam containers will start softening way before the heat reaches this degree. 212F 100C is enough to soften containers made from this materialSep 11. What is the melting point of styrofoam.
Styrofoam is a trade name of expanded polystyrene EPS therefore its softening temperature range is that of PS which is around 240 deg C. Actually this is the temperature that PS softens and becomes fluid as there is no melting point or range for PS because it is not a crystalline polymer. Will Styrofoam melt at 170 degrees.
You should never put styrofoam containers in the oven. Styrofoam made from expanded polystyrene doesnt withstand high heat. It will start softening at 212F and melting at 464.
You can use styrofoam containers to preserve food in the fridge but never reheat or cook with them in the oven. Styrofoam will start softening at 212 degrees F and melting at 464 degrees F but that doesnt mean you should use it in the oven regardless of the temperature. Styrofoam is made from expanded polystyrene meaning that it cannot accommodate extreme temperatures.
Styrofoam can both burn and melt however its worth noting that it is much more likely to melt than to burn. Youll find that around 212-238 degrees Fahrenheit 100 120 Celsius that it starts to noticeably deform and then at around 320 degrees it will melt. Originally Posted by h3llfir3.

Its true that polystyrene is lightweight and is 95 air so it does indeed weigh less than paper but that isnt the real story. What they fail to tell you is that 25-30 of the total amount of space in our landfills is taken up by polystyrene and other petroleum-based plastics. It will be around for a looonnnggg time.
Styrofoam is flammable at higher temperatures and can catch fire. It will melt at 212 degrees Fahrenheit ignite with a spark at 680 degrees Fahrenheit and auto-ignite at 800 degrees Fahrenheit. Nichrome provides a high tensile strength and high melting point.
It offers durability for continuous use. Most foam products will require a wire capable of reaching 600F 315C or higher. To heat 18 AWG Nichrome to this temperature range will require 65 amps.
At 20 AWG you need just over five amps. It does not melt. It starts softening around 100 oC.
Around this temperature it undergoes what is called a Glass Transition moving from being hard and brittle Glassy to a soft rubbery material. This 100oC is referred to as the Glass Transition Temperature of the polymer Tg. Foam or foamy describes how something looks or feels.
So there really is no melting point unless you say what is the foam made of. So like the foam that comes as styrofoam or DOW chemicals name. At what temperature does resin melt.
First of all it doesnt melt. However if it is the softening and disintegrating that we are talking about it is different for different resin variations. Does resin melt Styrofoam.
In short the answer is YES. The resin will eat your Styrofoam. Once the foam is exposed to temperatures above 180F for extended periods of time the foam starts to degrade more quickly leading to shorter lifespan for the foam.
