EXPANDED POLYSTRENE
* Expanded Polystyrene (EPS) is a lightweight rigid foam material that is made by the polymerization of styrene, an oil derivative also found naturally in foods such as strawberries, nuts and beans. The blowing agent employed is pentane which is neither a CFC nor an HCFC.
* EPS is a versatile durable material that offers excellent insulation properties. As the structure of EPS consists of 98% air its initial thermal properties are maintained throughout its working life.
* It is commonly used in the construction of thermal insulation panels.
