Modacrylics are sensitive to loss of appearance due to improper care; therefore, it is important to know how to care for modacrylics. Modacrylics are resistant to acids, weak alkalis, and organic solvents. These fibers are also resistant to moths, mildew and sunlight. Modacrylic fabrics can be machine washed using warm water and tumble dried on ...
It is a brominated aromatic chemical used principally for giving flame retardant properties to materials. [1] It is TSCA and REACH registered and has the molecular formula C 21 H 20 Br 4 O 4 . The IUPAC name is 2-{[2,6-dibromo-4-(2-{3,5-dibromo-4-[(oxiran-2-yl)methoxy]phenyl}propan-2-yl)phenoxy]methyl}oxirane.
Polybrominated diphenyl ethers or PBDEs, are a class of organobromine compounds that are used as flame retardants.Like other brominated flame retardants, PBDEs have been used in a wide array of products, including building materials, electronics, furnishings, motor vehicles, airplanes, plastics, polyurethane foams, [1] and textiles.
Typically, their undergarments beneath the heavier fire-resistant gear are made of flame-retardant cotton or another breathable, organic fabric that has been treated to resist ignition. [ 20 ] Polymers containing nitrogen , sodium , and phosphorus atoms can work as materials for fire-resistant cellulosic textiles, such as cotton or rayon .
Fire-retardant materials should not be confused with fire-resistant materials. A fire resistant material is one which is designed to resist burning and withstand heat . An example of a fire-resistant material is one which is used in bunker gear worn by firefighters to protect them from the flames of a burning building.
The brominated variety of commercialized chemical flame retardants comprise approximately 19.7% of the market. They are effective in plastics and textile applications like electronics, clothes, and furniture. 390,000 tons of brominated flame retardants were sold in 2011. This represents 19.7% of the flame retardants market. [1]

It is used to prepare fire-resistant polycarbonates by replacing some bisphenol A. A lower grade of TBBPA is used to prepare epoxy resins, used in printed circuit boards. TBBPA is also converted to tetrabromobisphenol-A-bis(2,3,-dibromopropyl ether) (TBBPA-BDBPE) which can be used as a flame retardant in polypropylene.
