What Is eps? 

Expanded Polystyrene EPS is a rigid cellular plastic that is made from expandable polystyrene that contains an expansion agent. During the material production process called "Polymerization" the polystyrene resin granules impregnated with the blowing agent. EPS production processes begin in the pre-expansion process where the EPS bead will expand by the heat of steam usually 50 times in volume. Next step is molding process where expanded polystyrene foam bead will be heated again with steam then they expand further until they fuse together, forming as EPS foam products.
There are two kinds of Polystyrene Foams:
1. Expandable Polystyrene / EPS usually use as packaging for many kind of products such as television, electrical appliances, helmet, ice box, sheet foam and block foam for road construction.
2. Polystyrene Paper / PSP so called Extruded Polystyrene / XPS which use to produce food tray and food box.

EPS Application

EPS Packaging:
EPS is used widely as a packaging medium for a variety of products. FMS EPS is widely used to package fresh fish and produce, as it is able to help keep food fresh through the distribution chain.  Expanded polystyrene is also used within the pharmaceutical industry to package items that are temperature sensitive, and need to be transported throughout the world.. The thermally insulative and moisture resistant properties of expandable polystyrene enables freshness extension of perishable products such as produce and seafood. Moreover, its compression resistance means that EPS is ideal for stackable packaging goods. The majority of expanded polystyrene packaging manufactured in Australia is used in the transport of fruit, vegetables and seafood. EPS packaging is used extensively for both the domestic and export market.
EPS Building and EPS Construction:
Considerable quantities of FMS EPS are also used in the building and construction industry. Flame retardant EPS is an inert material that does not rot and is not susceptible to attack by pests such as rats or termites. Its strength and durability makes it a versatile building product however its primary use is as custom insulation in building applications ranging from walls, roofs and floors. EPS FSA is also used as a void-forming fill material in civil engineering projects, as a lightweight fill in road and railway construction, and as floatation material in the construction of floating pontoons and yachting marinas.
Other:
When safety is paramount, EPS comes into its own. Expanded polystyrene can be used as an insulator against heat and the cold. It is good at absorbing shocks and protecting delicate items æ for example your head when used as part of a cycle crash helmet. EPS is the most versatile insulation product used in electrical consumer goods and insulation panels for building. It is used in the manufacture of children's car seats and cycling helmets, where its protective qualities such as strength and shock-absorbency are vital. EPS also has applications in horticulture as seedling trays. Granulated EPS can also be added as a soil conditioner to promote aeration of the soil.
