What is Expanded Polystyrene

Expanded Polystyrene (EPS) is a closed cell, lightweight, rigid foam plastic. EPS is also commonly known as Styrofoam. It is composed of carbon and hydrogen molecules, which is derived from petroleum and natural gas by-products.


Molded EPS is non-toxic and no chlorofluorcarbons, usually referred to as CFCs, are used in the production. 

EPS is environmentally friendly. Due to its strength and excellent insulation value, less material is needed. Less energy is used in the manufacturing compared to alternative materials. EPS does not support microbiological growth. 


EPS has properties of low thermal conductivity, high compressive strength, and excellent shock absorption properties which makes it an ideal material for an insulating concrete forming system. EPS foam is also the material commonly found in protective cushion pads for computers, and other electronic equipment.

Environmental safety: 
EPS has no nutritional value to support fungal, bacteriological or animal growth. This makes it an ideal material for food packaging. EPS is also non-toxic and inert, and contains no chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs).


EPS is made of 98% air, making it one of the lightest packaging materials. EPS adds therefore very little to the weight of the packaging.


Expanded Polystyrene is 100% recyclable and reusable.


Insulation capacity:

The thermal insulating properties of EPS helps keep food fresh and prevent condensation throughout the distribution chain. 


The exceptional durability of EPS makes it an effective and reliable protective packaging for a wide range of goods. The cellular structure of EPS makes it dimensionally stable and therefore does not deteriorate with age.


Mechanical strength: 
Flexible production makes EPS versatile in strength which can be adjusted to suit the specific application. EPS with high compressive strength is used for heavy load bearing applications, whereas for void forming EPS with a lower compressive strength can be used.  

EPS can be manufactured in a wider range of shapes and sizes than other materials. It is also compatible with cement, concrete, brick, masonry, mortars and plaster. EPS can be custom-shaped to protect all kinds of products. This reduces the amount of packaging required, resulting in savings on space, distribution and damaged-goods costs.

Ease of transport and installations: 
Because EPS is lightweight, it is easy to transport and saves fuel resources during transportation. EPS is also easy to handle, store and install, and does not require wear of protective clothing.
