Negotiations between the EPA and the two U.S. producers of DecaBDE (a flame retardant that has been used in electronics, wire and cable insulation, textiles, automobiles and airplanes, and other applications), Albemarle Corporation and Chemtura Corporation, and the largest U.S. importer, ICL Industrial Products, Inc., resulted in commitments by these companies to phase out decaBDE for most

HBCD (Hexabromocyclododecane) • HBCD is a high volume (20,000t worldwide), additive brominated flame retardant i.e. directly applied to the product requiring flame retardancy • HBCD has been used for 20 years • Major applications: • Extruded or expanded polysterene foam e.g rigid insulation panels, blocks for construction

Substitute materials do however exist. Alternates to insulating materials such as mineral rock wool can also prevent the use of HBCD. “Some historical uses of HBCD, such as consumer upholstery and textiles for furniture and cars, as well as cases for electronics like televisions,” have been phased out, said Daniel Rosenberg 2021-04-23 · Lipids including ((4-hydroxybutyl)azanediyl)bis (hexane-6,1-diyl)bis (2-hexyldecanoate), 2 [ (polyethylene glycol)-2000]-N,N-ditetradecylacetamide, 1,2-Distearoyl-sn-glycero-3- phosphocholine, and cholesterol): These lipid droplets, according to Reuters, help transport the working parts of the vaccine to the human body, allowing an immune response to occur. of the main chemical sub-species of HBCD.

(PBT) characteristics. HBCD use as a flame retardant in EPS and XPS accounts for more than 95% of HBCD applications. EPS and XPS are used as rigid foam insulation in the building and construction industry. A small volume of HBCD is used in textiles and high-impact polystyrene (HIPS). The main use for HBCD is as an additive-type flame retardant for extruded and expanded polystyrene foam. Other applications include crystal and high-impact polystyrene , SAN (Styrene-AcryloNitrile) resins, adhesives, and coatings. Hexabromocyclododecane, commonly known as HBCD, is a flame retardant that is starting to give a lot of green builders headaches.

TBBPA and HBCD were not detected in children's products and furniture at levels consistent with use as a flame retardant in products tested by Ecology.

Examples of HBCD activities include: Optimizing assessment (e.g., neurocognitive testing) and imaging techniques (e.g., magnetic resonance imaging [MRI]) from prenatal stages through childhood Developing standardized analysis pipelines for imaging and behavioral and cognitive testing Using real-time MRI to analyze brain development HBCD is used mainly in polystyrene insulation material for buildings – both in expandable polystyrene (EPS) and extruded polystyrene (XPS). It may also be found in packaging plastics made of EPS, for example in EPS packaging for globally traded electrical and electronic equipment. HBCD stands for Hexabromocyclododecane. Up to now it has been used mainly in insulating wall panels and in future certain uses will be allowed for a limited period.
