The advantages of polystyrene

The advantages of polystyrene

Over the past few years, polystyrene has come under fire by environmentalists. However, those that are questioning the environmental aspect and sustainability of polystyrene have got the facts wrong. Polystyrene in actual fact has many advantages, including those that impact the environment.

Here are just three of the many advantages polystyrene has to offer:

Sustainable and smart

Contrary to what many environmental activists say expanded polystyrene is extremely sustainable. When manufactured, only 2% of EPS is polystyrene ⁠— the rest is air. Polystyrene is also a significantly versatile material making it superior to all other materials in terms of the shapes and colours polystyrene is available in. This material is also ideal for protecting sensitive or breakable objects and products during both transportation and storage.

Expanded Polystyrene (EPS) manufactured by the Isowall Group is fast becoming recognized as the insulation material of choice by specifiers of “Bills of Quantities”. This comes largely as a result of our technical knowledge backed up by years of experience in the building and construction industry.


Polystyrene products are often used to store food products as it protects the food from bacteria and moisture. This guarantees the quality of the food is preserved; the shelf-life of the product is extended and prevents the spread of disease. It is safe to come into contact with food products as it is not a toxic material. This is due to the fact that the monomer polystyrene is made from, styrene is a natural product that can be found in foodstuffs ranging from beans and strawberries to wine and coffee beans. Therefore, the polystyrene product is able to come into contact with food with no negative consequences.


The low weight nature of polystyrene results in the reduction of fuel consumption when transporting polystyrene goods. This, therefore, reduces environmental impact. The environmental benefits of polystyrene also include the fact that it does not damage the ozone due to the fact that chlorofluorocarbons (CFC’s) are not used in the production process of polystyrene.

The Isowall Group has been manufacturing and distributing Isolite Block Moulded EPS since 1985, and Isolite Shape Moulded EPS since 1992. Isolite EPS products are used primarily for insulation, lightweight fillers and semi-rigid cushioning. 

Isowall is the supplier of choice within Africa for Insulated Sandwich Panel, EPS and EPP products. Contact us for more information.
