Sintered expanded polystyrene (EPS) is a rigid, light weight material derived from petroleum composed of carbon and hydrogen atoms.

Through chemical industrial processes, a closed cell structure is formed inside polystyrene expanded beads, which keeps the air inside, preventing convective motions, thus giving the expanded polystyrene excellent insulating properties.

Sintering is the welding process of expanded polystyrene beads which, once again subjected to the action of water vapor, are joined together to form a homogeneous block of expanded material. Sintered expanded polystyrene generally has a volume mass of between 10 and 40 Kg / mc, and is therefore on average made up of 98% air and only 2% of pure hydrocarbon structural material. Suitable for cladding, insulation of attics, roofing, interior partitions etc. Not indicated when you are in direct contact with water.
