What does BR stand for?

1%) bromine (if the bromine source is from brominated flame-retardants) and <1000 ppm (0.

These new measurements will help scientists to better understand sources of these bromine species and to improve simulations of stratospheric ozone chemistry.

a leading manufacturer of bromine, crude salt and specialty chemical products in the People s Republic of China, today announced that one of its wholly-owned subsidiaries Shouguang City Haoyuan Chemical Company Limited has signed an agreement with three individual residents of the People s Republic of China, Fenqiu Yuan, Han Wang and Yufen Zhang, to acquire manufacturing assets involved in bromine and crude salt production.

In this work, much attention has been focused on evaluating the elastomeric characteristics of SBR, which reacts with different ratios of bromine to acquire flame retardancy characteristics.

Under the agreements, which are each 20 years or more in length, Tetra will acquire its bromine requirements from Chemtura; Tetra will make a significant investment in the construction of a processing facility on property adjacent to Chemtura's El Dorado, AR, facility for the extraction of calcium chloride and other salts from tall brines purchased from Chemtura; Tetra will make an investment in Chemtura's bromine operations; Tetra will sell sodium chloride and magnesium hydroxide extracted from the tail brine to Chemtura for use as a feedstock for chlorine production and as a flame retardant and/or neutralization agent, respectively; and Chemtura will have the right to participate in future development or purchase of Tetra's brine leases, should Tetra elect to joint develop or divest.

The company said the project will include brine production wells, a bromine plant, a calcium chloride plant and the expansion of Tetra's existing West Memphis bromide facility.

A year ago, Albemarle introduced its first PBDE replacement, Saytex RX 8500, a less expensive, reactive brominated compound that locks the bromine into the foam matrix.

Water analysis specialist Palintest has introduced an easy-to-use, hand-held meter for the accurate determination of bromine and chlorine levels in water.
