Tetrabromobisphenol A | C15H12Br4O2
USE: 2,2',6,6'-Tetrabromobiphenol A is an important commercial chemical. It is used as a flame retardant in electronics, paper, plastics, textiles and to make other chemicals. It is also applied to carpeting and furniture. EXPOSURE: Workers that use 2,2',6,6'-tetrabromobiphenol A may breathe in vapors or mists or have direct skin contact.
Production and use. TBBPA is produced by the reaction of bromine with bisphenol A. Most commercial TBBPA products consist of a mixture that differ in the degree of bromination with the formula C 15 H 16−x Br x O 2 where x = 1 to 4. Its fire-retarding properties correlate with %Br.The annual consumption in Europe has been estimated as 6.200
Tetrabromobisphenol A; Final Test Rule | Assessing
EPA is issuing a final test rule, under section 4 of the Toxic Substances Control Act (TSCA), requiring manufacturers and processors of tetrabromobisphenol A (TBBPA. CAS No. 79—94—7) to perform testing for chemical fate and environmental effects.
Tetrabromobisphenol-A (TBBPA; Fig. 28.3), the highest volume flame retardant worldwide, is primarily (90%) a reactive BFR covalently bound to the polymer structure and less likely to be released into the environment than are additive flame retardants (Birnbaum and Bergman, 2010). It is used mainly for the production of circuit board polymers.
Tetrabromobisphenol A: Disposition, kinetics and toxicity
Tetrabromobisphenol A (TBBPA) is a nonregulated brominated flame retardant with a high production volume, and it is applied in a wide variety of consumer products. TBBPA is ubiquitous in abiotic matrices, wildlife and humans around the world.
Is the flame retardant, tetrabromobisphenol A (TBBPA), a
Two studies examined the effects of tetrabromobisphenol A (TBBPA) at oral doses of 10,100 or 1000 mg/kg bw/day over the course of 2 generations on growth as well as behavioral, neurological and
US20070190872A1 - Fire retardant silicone textile coating
The invention also includes a method for making a fire resistant textile product, the method comprising preparing a fire retardant textile coating comprising a plurality of FR agents, applying the FR textile coating to a textile substrate, and curing the FR textile coating, thereby producing the fire resistant textile product.
Polyamide composition, stabilized with copper salt and an
You can also use a mixture of halogenated organic compounds. Add the amount of halogenated organic compounds is usually less than 10 wt.%. Usually add such quantity that they use 50-30000 hours /million halogen, with respect to the whole composition. Use preferably 100-10000 hours /million, particularly preferably 500-1500 hours/million, halogen.
Metra radio Data Interface with SWC for Chrysler/Dodge/Jeep
When replacing the OEM radio with an after market radio some feature are lost. With this interface most of those features are retained. This interface will provide and retain 12 volt accessory power, provides navigation outputs, retain steering wheel controls.
Quality Concepts for the Improved Use of Recycled Polymeric
Three BFRs families dominate the organic flame retardant market: tetrabromobisphenol A (TBBPA), polybrominated diphenyl ethers (PBDEs), and hexabromocyclododecane (HBCD). Flame retardants can be either reactive, when they are chemically bonded to the polymeric matrix, or additive, when they are added during processing.
Odor characterization of post-consumer and recycled
Cresols are known to be derivatives of antioxidants (Campbell and Wise, 1963, Newland and Tamblyn, 1965), while 4-isopropylphenol may be associated with the decomposition of the brominated flame retardant tetrabromobisphenol A (TBBPA), commonly used in ABS (Hall and Williams, 2008). Another brominated flame retardant found in w-PP and r-PP
US7837912B2 - Methods of forming a layered article - Google
A method of forming a layered article, the method comprises thermoforming a substrate sheet to form a shaped substrate, wherein the shaped substrate is a fiber-reinforced plastic material having a void content sufficient to allow a vacuum to be applied through the shaped substrate; pulling a vacuum through the shaped substrate; and pulling a film layer onto a surface of the shaped substrate to
