Expanded Polystyrene (EPS)

Expanded Polystyrene (EPS) is a form of polystyrene that is expanded using a blowing agent to create a foam with a cellular structure. This process results in a material that is both lightweight and highly insulating. EPS is non-biodegradable and often used in applications requiring low-density and high-strength properties. It can be molded into complex shapes, making it a popular choice in packaging, construction, and insulation. While EPS is highly efficient as an insulator, it is sensitive to UV degradation and must be protected if used outdoors.

Technical Characteristics:

Applications:

• Disposable food containers and cups
• Building materials (insulating panels)
• Model making and construction prototypes
• Surfboards and flotation devices
• Packaging materials (protective cushioning for fragile goods)
• Thermal insulation in buildings and refrigeration

Environmental Impact of EPS

EPS is non-biodegradable and contributes to long-term waste if not properly disposed of. It is lightweight, which makes it prone to wind dispersion and littering in the environment. Recycling of EPS is possible but challenging due to its low density and contamination. Efforts to improve recycling technologies and reduce single-use EPS are ongoing, with alternative biodegradable solutions being explored.

Safety Measures and Regulations for Handling EPS

EPS is generally safe to handle, though care should be taken during processing. When exposed to high temperatures or fire, it can release harmful fumes such as styrene and other volatile compounds. Proper ventilation and fire safety measures are essential. Compliance with local safety regulations (OSHA, EPA) is important to ensure safe handling and disposal.

Packing

EPS is typically supplied in 25 kg bags or bulk containers
