Polystyrene is flammable, and releases large amounts of black smoke upon burning. Expanded polystyrene is lightweight. This is a man in Guiyang, China carrying a lot of expanded polystyrene packaging. In chemical terms, polystyrene is a long chain hydrocarbon wherein alternating carbon centers are attached to phenyl groups (a derivative of ...
Animals do not recognize polystyrene foam as an artificial material, may mistake it for food, and show toxic effects after substantial exposure. Full or partial bans of expanded and polystyrene foam commonly target disposable food packaging. Such bans have been enacted through national legislation globally, and also at sub-national or local ...
Due to its persistence, toxicity, and ecotoxicity, the Stockholm Convention on Persistent Organic Pollutants decided in May 2013 to list hexabromocyclododecane in Annex A to the convention with specific exemptions for production and use in expanded polystyrene and extruded polystyrene in buildings. Countries may choose to use this exemption for ...
The new ordinance bans the distribution and sale of expanded polystyrene products, which are commonly referred to by the trade name Styrofoam. Los Angeles officials ban Styrofoam products in move ...
Rigid cellular polystyrene (RCPS). This includes extruded polystyrene foam XPS (such as Styrofoam and commonly referred to as "blue board," expanded polystyrene foam EPS (commonly referred to as "beadboard"), and MEPS. Polyisocyanurate (also known as polyiso). More stable at high temperatures and less flammable than polyurethane.
Styrofoam insulation extruded polystyrene foam (XPS), owned and manufactured by DuPont. Styrofoam is a genericized trademarked brand of closed-cell extruded polystyrene foam (XPS), manufactured to provide continuous building insulation board used in walls, roofs, and foundations as thermal insulation and as a water barrier.
Megan Liu, lead study author and science and policy manager at Toxic-Free Future, tells Yahoo Life that this was a “minor point” in the study. “We feel bad that this happened,” she adds.
Considered a pioneering category of products, the rigid foam insulation is made of a modified expanded polystyrene (EPS), which includes a brominated fire retardant called HBCD (hexabromocyclododecane) which promotes self extinguishing once removed from direct flame. The EPS used in insulated siding has a density of 1.0 lb/cu ft (16 kg/cu m).
