China however, permits the use of HBCD in expanded and extruded polystyrene foam for building applications until December 2021. More detailed information about international risk management is available in Annex B. 2.5.3 Proposed changes to exemptions under the regulations SHOULD CONSIDER CRITICAL USES FOR HBCD ARLINGTON, VA (Aug. 18, 2010) – The Environmental Protection Agency (EPA) today released an action plan on HBCD (hexabromocyclododecane). The following is a statement from Mike Walls, ACC vice president of regulatory and technical affairs. 3. HBCD is used as a flame retardant additive, with the intent of delaying ignition and slowing subsequent fire growth during the service life of vehicles, buildings or articles, as well as while materials are stored.

HBCD may also be used as a flame retardant in textiles. HBCD is a flame retardant found primarily in polystyrene foam used as an insulation material in the building and construction industry. Flame retardants are chemicals that inhibit or reduce the spread of fire when added to combustible material such as clothes and plastic casings. The main use for HBCD /1,2,5,6,9,10-hexabromocyclododecane/ 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. What are the uses of HBCD?

The main pools for HBCD have been identified and possible dispersion pathways have been discussed. The year of 2001 was used as a reference year. The main pools for HBCD Cite · Download full-text av PO Darnerud · 2010 — In trying to standardize dust sampling, dust was also sampled by an accompanying person from NFA by use of a specific dust sample device.

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 Instead, it uses an adenovirus vector to get the needed instructions to our cells. The adenovirus vector is essentially a harmless cold virus that cannot replicate itself in our body nor can it cause disease. Therefore, it has been used as a platform for a variety of vaccines. minoxidil solution, and examples of the use of β-cyclodextrin derivatives are SBE -β-CD in the intravenous antimycotic voriconazole, HP -β-CD in the antifungal itraconazole, intravenous and oral solutions, and RM-β-CD in a nasal spray for hormone replacement therapy by 17β-estradiol.

Other uses include use as a component of solder and use in automobile replacement parts. Chemical makers and environmental advocates are praising a move last week by governments from around the world to end production and use of the flame retardant hexabromocyclododecane (HBCD research strategy should include a comprehensive assessment of substance use history to permit accurate estimates of pre-/perinatal exposure of substance use (e.g., opioids, marijuana, tobacco/nicotine, alcohol, psychostimulants, hallucinogens, etc.) using multi-modal approaches HBCD 79, 81, 160 HBB 79, 81, 551.5 PBEB 79, 81 BTBPE 79, 81 DBDPE 79, 81 BDE-209 484.6 13C-BDE-155 (IS) 334.8 13C-BDE-209 (IS) 496.6 Quality assurance All solvents used were tested for trace amounts of analytes. The glassware was either rinsed with acetone or heated in an oven at 450°C for at least 3 hours before use.

Flame retardants are used to slow the ignition and spread of fire. At the time of the assessment, HBCD was mainly used as a flame retardant in polystyrene foam insulation for building materials. In nature, cyclic dextrins are produced by the bacteria which break down carbohydrates. However, it can also be synthesized from starches by making use of certain enzymes and the by-products can be refined further for several uses.

EPS and XPS are used primarily for thermal insulation boards in the building and construction industry. HBCD may also be used as a flame retardant in textiles.
