Key Differences
Styrofoam is a trademarked brand name owned by The Dow Chemical Company for its blue extruded polystyrene foam (XPS), primarily used in building insulation and construction projects. Thermocol, often a colloquial term, generally refers to expanded polystyrene foam (EPS), a lightweight material used in packaging, disposable containers, and art and craft applications.
Styrofoam's structure is more rigid, dense, and moisture-resistant, making it suitable for insulation purposes. In contrast, Thermocol is less dense, has a more airy structure, and is widely used for its cushioning and insulating properties in packaging.
The manufacturing process of Styrofoam involves the extrusion of polystyrene, while Thermocol is made by expanding polystyrene beads, resulting in a different cellular structure and physical properties.
In terms of environmental impact, both Styrofoam and Thermocol pose challenges in disposal and recycling due to being polystyrene-based products. However, their lightweight and insulating properties make them popular in their respective applications.
While the term Styrofoam is often used interchangeably with polystyrene foam products, it technically refers to a specific type of XPS. Thermocol, commonly used in India and other regions, usually indicates EPS products.
