Extruded Polystyrene (XPS)
XPS is an aromatic polymer made from the aromatic monomer styrene, a liquid hydrocarbon that is commercially manufactured from petroleum by the chemical industry. Crystal polystyrene is one of the most widely used kinds of plastic.
XPS is a thermoplastic substance, which is in solid (glassy) state at room temperature, but flows if heated above its glass transition temperature (for molding or extrusion), and becomes solid again when it cools off.
Products made from foamed polystyrene are nearly ubiquitous, for example packing materials, and insulation,
Polystyrene can be recycled, and has the number “6” as its recycling symbol. Polystyrene does not biodegrade.
The raw material (bead) is imported.
The extrusion manufacturing process gives XPS many benefits over expanded polystyrene and polyurethane, including superior thermal properties, superior load bearing capacity, and increased moisture resistance. These qualities produce a more energy efficient building, with a longer lifecycle and a quicker payback period.
Extruded Polystyrene is an exceptionally versatile product, and as a result it can be used in a multitude of applications.
