Eps Foam – Expanded Polystyrene Foam (Styrofoam)

EPS foam stands for Expanded Polystyrene foam. It is a lightweight, rigid, closed-cell foam material derived from polystyrene. EPS foam is manufactured by expanding polystyrene beads with steam and then molding them into various shapes and sizes. It is widely used in packaging, insulation, construction, and a variety of other applications due to its versatility, thermal insulation properties, and cost-effectiveness. Often the public refers to EPS as Styrofoam which is a Dow Chemical brand name extruded foam sold in blue sheets and used as insulation.

A specific type of EPS Foam is called Geofoam. Geofoam is used as a fill in construction applications. Geofoam is designed to meet specific geotechnical engineering standards and load requirements.

Here are some key characteristics and properties of EPS foam:

Lightweight:

EPS foam is extremely lightweight, making it easy to handle, transport, and install in various applications.

Rigid and Durable:

Despite its lightweight nature, EPS foam is rigid and durable, providing structural support and protection in packaging and construction applications.

Closed-Cell Structure:

EPS foam has a closed-cell structure, meaning its individual cells are sealed off from each other. This structure provides excellent thermal insulation properties, as it reduces heat transfer and helps maintain temperature stability.

Excellent Thermal Insulation:

EPS foam is an effective thermal insulator, helping to reduce heat loss or gain in buildings and refrigeration units. It is commonly used in insulation boards, panels, and sheathing to improve energy efficiency and comfort.

Moisture Resistance:

EPS foam is resistant to moisture, making it suitable for use in humid or wet environments. It does not absorb water, which helps prevent mold, mildew, and rot.

Versatility:

EPS foam is available in various densities, thicknesses, and shapes to suit different applications. It can be molded, cut, shaped, and formed into custom configurations for packaging, insulation, and construction needs.

Cost-Effective:

EPS foam is cost-effective compared to other insulation materials, making it a popular choice for budget-conscious projects. Its affordability, combined with its thermal insulation properties, makes it a preferred insulation solution in many applications.

Recyclable:

EPS foam is recyclable and can be reused or repurposed into new products through recycling programs. Recycled EPS foam can be used to manufacture a variety of products, including insulation, packaging materials, and consumer goods.
