Our product, High Quality Tetrabromobisphenol A with CAS number 79 - 94 - 7, is a well - known flame retardant in the market. It has a white or almost white powder appearance. The molecular formula of Tetrabromobisphenol A is C₁₅H₁₂Br₄O₂, and its molecular weight is approximately 543.97 g/mol.
The melting point of this product ranges from 178 - 181°C (352 - 358°F), and it has a density of about 2.17 g/cm³. It is sparingly soluble in water but soluble in organic solvents such as acetone, methanol, and benzene. With high purity, our Tetrabromobisphenol A ensures consistent performance in various applications.
Tetrabromobisphenol A is primarily used as a flame retardant in a wide range of industries. In the plastics industry, it is added to various polymers such as polycarbonate, epoxy resin, and acrylonitrile - butadiene - styrene (ABS) to improve their fire resistance. For example, in electronic appliances' plastic casings, the addition of Tetrabromobisphenol A can prevent the spread of fire in case of an electrical short - circuit, thus enhancing the safety of the products.
In the textile industry, it can be used as a finishing agent to impart flame - retardant properties to fabrics. This is especially important for textiles used in public places, such as curtains, carpets, and upholstery, where fire safety is a major concern.
It is also used in the production of printed circuit boards. By incorporating Tetrabromobisphenol A into the resin matrix of the circuit board, the board becomes more resistant to ignition, which is crucial for the reliable operation of electronic devices.
When using Tetrabromobisphenol A, it is important to follow proper safety procedures. Wear appropriate personal protective equipment, such as gloves, goggles, and a dust mask, to avoid direct contact with the product. In the plastics industry, it can be added during the polymer compounding process. The recommended dosage usually depends on the specific polymer and the required level of fire retardancy, typically ranging from 5% to 20% by weight.
For textile finishing, it can be applied by padding or dipping methods. First, prepare an aqueous solution containing the appropriate concentration of Tetrabromobisphenol A and other necessary additives. Then, immerse the fabric in the solution and pass it through a mangle to remove excess liquid. After that, dry and cure the fabric at a suitable temperature.
In the production of printed circuit boards, it is mixed with the resin system during the formulation process. The mixture is then applied to the substrate and cured under controlled conditions to form a fire - retardant circuit board.
Case 1: A well - known electronics manufacturer was facing strict fire safety regulations for their new line of smartphones. They used our Tetrabromobisphenol A in the ABS plastic casings of the smartphones. By adding 10% of Tetrabromobisphenol A to the ABS resin during the injection - molding process, the casings passed the UL 94 V - 0 flammability test, which is a high - level fire - retardant standard. This not only helped the company meet the regulatory requirements but also enhanced the brand's reputation for safety.
Case 2: A textile mill producing curtains for a large hotel chain wanted to improve the fire - retardant performance of their products. They used a padding process with a 15% Tetrabromobisphenol A solution. After treatment, the curtains showed a significant reduction in flammability, meeting the local fire safety codes for public places. The hotel chain was satisfied with the improved safety features of the curtains and continued to place orders with the mill.
