Expanded polystyrene (EPS) is a generic term for polystyrene and styrene copolymers that are expanded into a variety of useful products. EPS is comprised of 90 percent air. The shock absorbing properties and other qualities of EPS foam, combined with its low-cost, high insulating properties, custom mold ability and ease of processing make it a popular industrial insulation material
For construction insulation applications the polystyrene foam industry has developed test data as reported in ASTM C 578 Standard Specification for Rigid Cellular Polystyrene Thermal Insulation. This standard addresses the physical properties and performance characteristics of EPS foam as it relates to thermal insulation in construction applications..
The uniform, closed cellular structure of EPS is highly resistant to heat flow. The thermal conductivity (k factor) of EPS packaging varies with density and exposure temperatures.
The most general usage area of polystyrene foam for heat insulation purposes are at Constructions; wall, ceiling, roof and prefabricated elements. Other areas of usage are for noise insulation, decorative ceiling boards and placing holes in concrete molds. The polystyrene that is pre swelled is used also at production of light concrete and light brick. In cooling technology, Polystyrene Foam material is being used at insulation of cooled warehouses, railway cars, ships, trucks and also at insulation of pipes. Durability of this material exposed to heat varies according to period and degree centigrade under exposure. Despite of the fact that it is durable against heat up to 100 °C for a short period, it is durable and can be used up to 75-85 °C according to its density for a long period.
