Expanded polystyrene (EPS) is a lightweight cellular plastic material consisting of small hollow spherical balls that are expanded through a molding process to create a cost effective and highly efficient material used in hundreds of different applications. EPS is widely used in many everyday applications where its light weight, strength, durability, thermal insulation and shock absorption characteristics provide superior benefits over other materials. These characteristics, combined with its versatility, performance and cost effectiveness have made EPS a packaging and building material of choice
