EPS

(EPS) is a product of styrene polymerization with the introduction of an expanding agent (gas) in the polymer composition. EPS is used in polymer processing into insulating panels and ready-to-use parts by expanding. The material has excellent heat-insulation and sound-proofing properties, high impact strength, vibration resistance, resistance to light, water repellency, dustproofness, and resistance to physical processing. The material is resistant to hydrolysis, oils, acids, solutions of alkalis and acids.

EPS is widely used in construction for production of panels for heat insulation

of walls and suspended ceilings (expanded plastic), as well as for production of thin-wall goods, fire-resistant industrial and food packaging.

Polystyrene is most commonly found in three forms. Rigid Polystyrene (PS), Expanded Polystyrene (EPS) and Extruded Polystyrene (XPS).
