Frequently Asked Questions
Is polystyrene foam the same as Styrofoam?
While "Styrofoam" is a brand name, polystyrene foam is the general term that refers to the material itself, which is used for insulation and packaging. Styrofoam is a specific type of polystyrene foam produced by the Dow Chemical Company.
What are the disadvantages of polystyrene foam?
Polystyrene foam has a low melting point, making it prone to deformation and melting at high temperatures, and it also absorbs water, compromising its structural integrity. Additionally, its low R-value indicates poor thermal insulation, making it less effective in maintaining a consistent temperature.
Is foam core the same as Styrofoam?
No, foam core and Styrofoam are not the same, although foam core contains a Styrofoam center. The key difference lies in the additional paper coatings surrounding the Styrofoam core.
Is polystyrene foam expensive?
No, polystyrene foam, also known as EPS sheets, is a relatively inexpensive material. Its affordability makes it a cost-effective option for various projects and applications.
