What is the melting point of styrofoam?

This is the sort of question that I'd usually answer with a link to LMGTFY, but in this case you get a pass, because you need to know what styrofoam is before you can get a good answer out of google. Styrofoam is made of polystyrene beads. read more

Styrofoam has no melting point, because the polymer it consists of - atactic polystyrene - is amorphous. It is solid up to its glass transition temperature of ~95°C, but the foam may start to collapse before due to gradual softening and stress release. read more

It is a rather poor barrier to oxygen and water vapour and has a relatively low melting point. Polystyrene is one of the most widely used plastics, the scale of its production being several million tonnes per year. read more

Polystyrene can "melt" but because it is not a simple chemical compound with a unique molecular structure there is not going to be one single "melting point." Polymers unlike metals can also burn and decompose and that is what is going to happen if you put this next to a hot lamp. read more
