Introduction

If you’re interested in learning more about the difference between expanded foam and polystyrene foam, then you’ve come to the right place! We’ll give you everything that you need to know about these materials so that you can make informed decisions regarding your next foam purchase.

What is the difference between expanded foam and polystyrene foam?

Expanded foam and polystyrene foam are both man-made materials. They’re different from each other, but they have many similarities as well. Let’s check out their differences!

Expanded Foam vs PolyStyrene Foam

Expanded foam is a lightweight, porous material made using air or gas to create cells in a polymer resin. It’s used for a wide variety of applications including packaging, insulation and construction. Typically speaking, expanded foams are more porous than polystyrene foams because they contain larger pores in their structure – this allows them to expand further without breaking apart when being used as an insulator or cushioning agent within packaging products (like egg cartons). Expanded foam is also less dense than polystyrene which means it can be lighter weight; however some people might argue that this makes it easier for them if they needed something strong enough like a building material (like walls).

Expanded Foam

Expanded polystyrene (EPS), also known as “expanded foam” or “polystyrene foam,” is a lightweight material made from polystyrene beads that have been expanded. The beads are heated up and then pressurized until they expand into a rigid, sponge-like structure. This process creates an open-celled structure that allows air to pass through the material, making it highly insulating. It also makes EPS very porous, so any moisture that gets absorbed into its pores will not be able to dry out easily, which makes it susceptible to mold growth if installed improperly or used in damp environments like bathrooms or basements where moisture may seep in through cracks in walls and floors.

Expanded polystyrene (EPS) insulation has many uses: it can insulate walls and attics; it can be used as packaging materials for shipping fragile goods; under certain circumstances it can even be used safely around food preparation surfaces in commercial kitchens because it does not absorb any odors or odors released by foods stored near these surfaces; however there is one major drawback: if not properly installed this type of insulation could lead directly into your health problems such as respiratory issues due its ability absorb moisture from nearby sources over time forming mold colonies which have been linked with asthma attacks among others!

Polystyrene Foam

Polystyrene foam is a lightweight material, so it’s used in packaging to help protect the products inside. It can also be used in construction, furniture and insulation. In addition, polystyrene is used in toys and other items that need to be light-weight. Polystyrene is also referred to as Styrofoam.

The main difference between expanded foam and polystyrene foam is that expanded foam becomes a very porous material, while polystyrene foam is used to create low density materials.

Expanded foam is a very porous material, while polystyrene foam is used to create low density materials. Expanded foam is used in insulation and is made from petroleum based products. On the other hand, polystyrene foam can be found in packaging and insulation as well. Both expanded and polystyrene foams are manufactured using different processes that give each of them unique properties that make them suitable for specific functions and applications.

Conclusion

I hope this information has helped clear up some misconceptions about the differences between expanded foam and polystyrene foam. Both materials have their advantages, but I believe that expanded foam is a better choice for most applications due to its versatility and durability.
