Expanded polystyrene

Polistirene espanso sinterizzato

100% recyclable

Because of outstanding properties in strength, ductility and insulation, expanded polystyrene (EPS) is used in many areas: from the energy saving solutions in construction to packaging for the transporting of industrial products, as well as prototyping the production of containers for food and flower products.

Strong, ductile and aseptic, the EPS is used in construction as insulation solution because it unites all high capacity of thermal insulation with a low environmental impact.  The sintered polystyrene, in fact, is 100% recyclable, and, in addition, replaces the use of non-renewable resources such as clay or quarry aggregates, avoiding the need for excavations and land consumption.

Contrary to what you might think, EPS is made up of 98% air.

The sintered expanded polystyrene is obtained through the polymerization of styrene, a monomer derived from petroleum, that, before being expanded, is in the form of small transparent beads.

The beads are made to swell up to 20-50 times their initial volume through vaporization and high temperature.  This forms the closed cell structure, full of air, that gives the polystyrene its exceptional thermal insulation and shocking absorbing properties.

Aseptic

EPS is a material devoid of any nutritional value to living beings.  Therefore, it prevents the proliferation of fungi, bacteria, or other microorganisms.  It does not rot or mildew.  These special characteristics make it ideal for thermal insulation in the building industry and for the production of food containers.

Non-toxic

EPS is an inert, that is stable in terms of chemistry and biology, and is absolutely non-toxic or hypoallergenic.  Free of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), EPS is not a danger to the environment or to groundwater.  In construction, where it is used for thermal insulation, it presents no risk factors as it does not release any toxic gas.  Even the handling and machining of it are absolutely safe, given the total impossibility of inhalation.

Breathable

EPS is permeable to water vapor, breathable, but at the same time waterproof.  It prevents the formation of mold in buildings where it is utilized as insulation material.

Flammable

Composed of carbon and hydrogen, EPS is by its nature a combustible material.  It begins its decomposition at about 230-260C, with the emission of flammable vapors, but only undergoes ignition at 450-500C.  To reduce the risk of combustion, in the building process, a suitable treated polystyrene that reduces the growth of fire is utilized (EPS / RF).  A technology that allows you to keep all of the outstanding performance of polystyrene, increasing safety.

Recyclable

Expanded polystyrene is 100% recyclable.  De.com has a production line specifically dedicated to the recovery of EPS coming from industrial waste and to their re-entry into the production process.  The recycling of post-consumer waste is regulated by the DL5 in February 1977 n. 22.
