The market demand for brominated polystyrene (BPS) continues to increase, and the industry development prospects are good

Brominated polystyrene, referred to as BPS, refers to a type of additive polymer brominated organic flame retardant. Brominated polystyrene appears as white or light yellow powder, is insoluble in water, does not contain polybrominated diphenyl ethers and polybrominated biphenyls, and is a class of products with high environmental protection, thermal stability, flame retardancy, light stability and good mechanical properties. Brominated flame retardant with antistatic properties, chemical stability, processing properties and other characteristics.

The main production routes of brominated polystyrene include bromination method and solvent method. The bromination method refers to the process of using polystyrene as the raw material and directly brominating it with a brominating agent to produce brominated polystyrene; the solvent method refers to using polystyrene as the raw material, dissolving it with dichloroethane solvent, catalyzing it with a catalyst, The process of preparing brominated polystyrene through bromination, neutralization and washing, solidification and separation. Since the solvent method consumes less bromine, it is currently the mainstream process route for industrial production of brominated polystyrene.

Brominated polystyrene is mainly used in the production and manufacturing of thermoplastic resins, including polyhexamethylene adipamide (PA66), polybutylene terephthalate (PBT), polyamide (PA), polyterephthalic acid Thermoplastic resins such as ethylene glycol ester (PET) and polyphenylene ether (PPO). Among them, PA is the main application field of brominated polystyrene.

PA, commonly known as nylon, is a basic industrial raw material that is widely used in automobiles, electronics, textiles, machinery and other fields. In 2022, its domestic output has reached 4.425 million tons. Currently, against the background of the continuous increase in domestic PA production, brominated polystyrene, as an important raw material, has continued to increase its demand. According to the “China Brominated Polystyrene (BPS) Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center It shows that domestic demand for brominated polystyrene will exceed 50,000 tons in 2022, a year-on-year increase of approximately 4.2%.

Globally, companies in the brominated polystyrene market mainly include international companies such as Lanxess of Germany, BASF of Germany, DuPont of the United States, Albemarle of the United States, and Clariant of Switzerland, as well as Tianyi Chemical, Xurui New Materials, Suli Fine Chemicals, Runke Chemical, Derun Chemical and other Chinese companies. At present, the global brominated polystyrene market is mainly dominated by two international companies, Albemarle of the United States and Lanxess of Germany, and the industry concentration is high; while domestic brominated polystyrene companies are mostly small and medium-sized enterprises, and the industry concentration is low .

Industrial analysts said that brominated polystyrene is an important type of brominated flame retardant. PA, PET, PBT and other thermoplastic resins play an important role in the production. Currently, driven by the rapid development of terminal automobiles, electronics and other fields, their market demand is increasing, and the industry development prospects are good. However, the current global brominated polystyrene market is still dominated by overseas developed countries, and domestic enterprises lack competitive advantages and voice. In the future, domestic enterprises will need to continuously improve their technical level and accelerate the improvement of their competitiveness.
