What is Extruded Polystyrene – XPS?

Image
  Extruded Polystyrene – XPS Generally, polystyrene is a synthetic aromatic polymer made from the monomer styrene, which is derived from benzene and ethylene, both petroleum products. Polystyrene can be solid or foamed. Polystyrene is a colorless, transparent thermoplastic, which is commonly used to make foam board or beadboard insulation and a type of loose-fill insulation consisting of small beads of polystyrene. Polystyrene foams are 95-98% air. Polystyrene foams are good thermal insulators and are therefore often used as building insulation materials, such as in insulating concrete forms and structural insulated panel building systems. Expanded polystyrene and extruded polystyrene are both made from polystyrene, but EPS is composed of small plastic beads that are fused together and XPS begins as a molten material that is pressed out of a form into sheets. XPS is most commonly used as foam board insulation. Extruded polystyrene (XPS)  is also a thermoplastic polymer. Extruded polyst

Why recycled polystyrene foam and EPS are your best choices

  We found two important facts about expanded polystyrene (also known as   EPS or polystyrene foam ). The first thing they point out is that EPS packaging is recyclable. The second thing is that it is a small part of our landfill and solid waste stream. EPS also makes up less than 1% of total municipal solid waste (by weight and volume). This is very encouraging considering that EPS is considered by many to be the unfit child of the recycling world.      Where did all this EPS and polystyrene foam come from?  Polystyrene was discovered by German pharmacist Eduard Simon in 1839. When he separated it from the natural resin, he didn't actually realize what he had discovered. Eighty years later, organic chemist Hermann Staudinger discovered that Simon had actually discovered a plastic polymer. Staudinger was eventually awarded the Nobel Prize in Chemistry for all his polystyrene-related research, and in the 1930s, BASF scientists discovered a way to produce polystyrene commercially. At
