PCBs: extra requirements. It was primarily used as a surfactant in the metal plating industry and in aqueous film-forming foam (AFFF) used in fire-fighting. Historically, PFOS was also used in a wide variety of surface treatments for textiles, upholstery, leather, carpet and packaging to provide water, oil, soil and grease repellent properties. 2018-08-14 · HBCD also has limited use in replacement parts for automobiles. Past uses of HBCD included use in high impact polystyrene for electrical and electronic appliances, such as audio-visual equipment, refrigerator lining, some wire and cable applications, and in the back coating of textiles.

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. HBCD is a specialized type of cyclic dextrin which is formed when enzymes are used to break down amylopectin.
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.

Hiren's BootCD is an independent CD that contains a start HBCD is also imported into Canada for use in EPS resin. Typical loading of HBCD in EPS and XPS is 0.5 – 1.0% by weight (EPSMA, CPIA, BSEF and XPSA 2009).
Flame retardants are chemicals that inhibit or reduce the
(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).
