4,4-Isopropylidenebis(2,6-dibromophenol): An Overview of its Properties and Applications
4,4-Isopropylidenebis(2,6-dibromophenol), also known as Tetrabromobisphenol A (TBBA), is a flame retardant chemical widely used in the production of plastics, electronics, and construction materials. INNO SPECIALTY CHEMICALS is a leading manufacturer and supplier of this chemical from China, providing high-quality products to customers around the world.
Properties of 4,4-Isopropylidenebis(2,6-dibromophenol)
TBBA is a white crystalline powder with a molecular formula of C15H12Br8O2. It has a melting point of 183-187°C and a boiling point of 540°C. TBBA is soluble in organic solvents such as acetone, chloroform, and methanol, but insoluble in water. It has a low vapor pressure and is stable under normal conditions.
TBBA is a highly effective flame retardant, thanks to its ability to release bromine atoms when exposed to heat or flame. These bromine atoms then react with the free radicals generated during combustion, interrupting the chain reaction and preventing the spread of fire. TBBA is also a good thermal stabilizer, protecting materials from degradation at high temperatures.
Applications of 4,4-Isopropylidenebis(2,6-dibromophenol)
TBBA is widely used in the production of plastics, particularly high-impact polystyrene (HIPS) and acrylonitrile-butadiene-styrene (ABS). These materials are commonly used in the manufacture of electronic components, automotive parts, and household appliances. TBBA is also used in the production of epoxy resins, which are used in coatings, adhesives, and composites.
TBBA is also used as a flame retardant in construction materials, such as foam insulation, roofing materials, and cables. It is effective in reducing the flammability of these materials, improving their fire resistance and safety.
Safety and Environmental Concerns
While TBBA is an effective flame retardant, there are concerns about its safety and environmental impact. TBBA is classified as a persistent organic pollutant (POP), meaning it is resistant to environmental degradation and can accumulate in the food chain. It has been found in waterways, soil, and marine organisms, and has been linked to adverse effects on human health and the environment. There are also concerns about its potential to leach out of products and into the environment or be released during disposal.
As a result, there is increasing interest in developing safer and more sustainable flame retardants to replace TBBA and other POPs. Researchers are exploring alternatives such as phosphorus-based flame retardants, which are less persistent and have lower toxicity.
Conclusion
4,4-Isopropylidenebis(2,6-dibromophenol) or Tetrabromobisphenol A (TBBA) is a widely used flame retardant chemical with effective properties. INNO SPECIALTY CHEMICALS is a leading manufacturer and supplier of this chemical, providing high-quality products to customers around the world. While TBBA has been effective in reducing the flammability of materials, there are concerns about its safety and environmental impact. As a result, there is growing interest in developing safer and more sustainable flame retardants to replace TBBA and other POPs.
