Introduction
Styrofoam is a widely used material in packaging, construction, and insulation. But there’s a lot of confusion around what it actually is. Many people use “Styrofoam” interchangeably with expanded polystyrene (EPS) or extruded polystyrene (XPS), assuming they’re all the same thing. While they share similarities, they’re not identical—and the differences matter, especially in industrial applications.
In this article, we’ll break it all down—the real definition of Styrofoam, its industrial applications, and the environmental impact.

What is Styrofoam?
Styrofoam is a brand name that refers to extruded polystyrene foam (XPS), a rigid, dense material different from expanded polystyrene (EPS). Styrofoam is commonly recognized in GCC markets for its role in insulation boards, packaging materials, and disposable food products. Due to its manufacturing process, Styrofoam is denser and offers better moisture resistance than EPS, making it ideal for construction and packaging solutions in hot climates.
How Did Styrofoam Come About?
Originally trademarked by Dow Chemical (now part of DuPont), Styrofoam has been in use since the 1940s. Today, it’s a well-known material used in construction, foodservice, and packaging industries. While Styrofoam has become a generic term for all types of foam, it technically refers to extruded polystyrene (XPS), which differs from expanded polystyrene (EPS).
Styrofoam vs EPS: What’s the Difference?
styrofoam or polystyrene (EPS) might look alike, but they differ significantly in their composition, insulation properties, and durability. Here’s a quick comparison:
- Composition:
- Styrofoam (XPS): Made from extruded polystyrene, Styrofoam is a rigid, dense foam with a smooth texture. It is commonly used in construction and high-performance packaging.
- EPS (Expanded Polystyrene): Made from polystyrene beads, EPS is lightweight, porous, and more fragile than Styrofoam. It’s commonly used in packaging and disposable products.
- Insulation Properties:
- Styrofoam (XPS): Offers superior insulation, especially in high-moisture environments, due to its closed-cell structure.
- EPS (Expanded Polystyrene): While it offers decent insulation, EPS is more porous and less moisture-resistant than Styrofoam.
- Durability:
- Styrofoam (XPS): More durable and resistant to moisture, making it ideal for construction and long-term insulation.
- EPS (Expanded Polystyrene): Lighter and less durable, making it better suited for disposable applications.

Styrofoam vs Thermocol: Are They the Same?
Thermocol is another name for EPS (Expanded Polystyrene), produced by BASF. Styrofoam (XPS), produced by DuPont, is made through an extrusion process, while Thermocol is made from expanded polystyrene beads. The key differences include:
- Composition and Process:
- Styrofoam (XPS): Produced through an extrusion process, Styrofoam is denser and more rigid than Thermocol.
- Thermocol (EPS): Made from expanded polystyrene beads, Thermocol is lightweight and more fragile than Styrofoam.
- Durability and Uses:
- Styrofoam (XPS): More durable, resistant to moisture, and suitable for construction and insulation.
- Thermocol (EPS): Better for lightweight packaging, disposable food containers, and products that don’t require high strength.
Here’s a quick comparison table to highlight the key differences and similarities between Styrofoam and EPS for better clarity.
| Features | Styrofoam (XPS) | Expanded Polystyrene (EPS) |
|---|---|---|
| Base Material | Polystyrene | Polystyrene |
| Manufacturing Process | Extrusion | Expansion |
| Texture | Finer, closed-cell structure | Coarser, open-cell structure |
| Insulating Properties | Higher | Lower |
| Brand | Dow Chemicals | BASF (Thermocol) |
| Environmental Impact | Similar, derived from petroleum | Similar, derived from petroleum |
Through this comparative lens, we can understand the differences between Styrofoam and EPS, despite their common ancestry.
Properties of Styrofoam: What Makes It Unique?
Styrofoam stands out for its lightweight, durable, and excellent insulating properties. Its closed-cell structure makes it moisture-resistant and more effective as a thermal insulator than EPS. Whether used in building insulation or packaging fragile items, Styrofoam’s denser, more rigid texture provides superior protection.

How Is Styrofoam (Polystyrene Foam) Made?
The production process for Styrofoam involves the following steps:
- Extrusion: Polystyrene pellets are melted and mixed with additives to enhance certain properties, such as rigidity and durability. The molten mixture is then extruded through a die, forming continuous sheets or boards of foam.
- Cooling and Shaping: As the extruded foam passes through the die, it undergoes rapid cooling, which solidifies the foam into its final shape. The foam is then cut into sheets or molded into specific shapes as needed for various applications.
- Finishing: After shaping, the Styrofoam products may undergo additional processes such as surface finishing or coating to improve appearance or performance.
What Is Styrofoam Used For? (Construction, Packaging & More in the GCC)
In the GCC, Styrofoam is commonly used for:
- Building insulation: Styrofoam boards are an excellent choice for roof, wall, and foundation insulation, especially in the harsh heat of the GCC region.
- Packaging: Styrofoam protects electronics, delicate machinery, and other fragile items during transit.
- Disposable food containers: Styrofoam is widely used for cups, plates, and takeout containers in the foodservice industry.
Environmental Impact: Is Styrofoam Bad for the Planet?
Styrofoam’s environmental impact is a significant concern, as it is not biodegradable and is difficult to recycle in many regions. However, global initiatives and advances in recycling technologies are working toward repurposing Styrofoam into new materials like insulation boards or even concrete additives. Many GCC countries are implementing strategies to reduce plastic waste, including Styrofoam, and push for more sustainable practices.
Can Styrofoam Be Recycled?
Yes, Styrofoam can be recycled, though it is not as widely recycled as other plastics. Some regions in the GCC are enhancing Styrofoam recycling efforts, converting it into reusable materials for construction, packaging, or even eco-friendly products. This helps mitigate environmental impact and encourage circular economy practices.
Styrofoam Regulations & Standards in the GCC
Each GCC country has varying regulations regarding the use of Styrofoam, especially for food packaging. Dubai, for example, has begun restricting the use of Styrofoam in certain applications due to its environmental concerns. Other countries in the region are introducing regulations to promote eco-friendly alternatives and recycling efforts for foam products.

FAQs
Q: What is another name for Styrofoam?
In the GCC, EPS (Expanded Polystyrene) is most commonly referred to simply as “foam.” The term “Styrofoam” is used in reference to extruded polystyrene, not just the Dupont brand itself. While Styrofoam is a trademarked brand, it is often used as a general term for all forms of extruded polystyrene.
Q: Is Styrofoam the same as thermocol?
No, Styrofoam and thermocol are often confused, but they are not the same. Styrofoam is made from extruded polystyrene (XPS), while thermocol is made from expanded polystyrene (EPS). Styrofoam has better heat insulation properties due to its closed wall structure, making it more suitable for thermal insulation than thermocol.
Q: Is EPS the same as Styrofoam?
No, EPS (Expanded Polystyrene) and Styrofoam (XPS) are different. Styrofoam is made from extruded polystyrene (XPS), whereas EPS is made from expanded polystyrene, which forms foam blocks by expanding tiny beads of polystyrene. Styrofoam is more rigid and denser than EPS, providing better insulation.
Q: What is Styrofoam used for?
Styrofoam is commonly used for insulation, packaging, and food containers. It is used to make products like beverage cups, egg cartons, disposable plates, and trays. It is also utilized in solid forms, such as in injection-molded eating utensils and compact disc packaging.
Q: What are Styrofoam sheets called?
Styrofoam sheets are commonly called expanded polystyrene (EPS) sheets or extruded polystyrene (XPS) sheets, depending on the type. While many people use “Styrofoam” as a general term, true Styrofoam is a trademarked brand of XPS produced by DuPont, primarily used for insulation. EPS sheets, on the other hand, are more commonly used in packaging, insulation, and construction.
