High-impact polystyrene production capacity continues to grow and market competition is increasing

Polystyrene (Polystyrene, abbreviated as PS) refers to a polymer synthesized from styrene monomer (SM) through free radical addition polymerization. It is a colorless and transparent thermoplastic. Polystyrene is one of the five most commonly used plastics in the world, second only to polyethylene, polypropylene and polyvinyl chloride. It is mainly used to make disposable tableware, automobile parts, packaging materials, toys, and construction in daily life. Materials, appliances and household items, etc.

Polystyrene (PS) includes general-purpose polystyrene (GPPS), expanded polystyrene (EPS), high-impact polystyrene (HIPS), etc. Among them, high-impact polystyrene (HIPS) is produced by free radical graft polymerization of styrene and rubber. It is a modified material of polystyrene. Its composition contains a certain proportion of rubber components and its toughness is higher than that of general-purpose polystyrene. The styrene has increased by about four times, and the impact strength has been greatly improved. The downstream applications mainly include the shells and internal parts of home appliances, the shells of electronic appliances, packaging containers, etc.

In 2018, expanded polystyrene (EPS) production capacity shrank, resulting in a decline in the overall production capacity of the polystyrene industry. In recent years, with the continuous development of downstream household appliances, daily necessities, construction, display and lighting materials and other industries, as well as the progress of my country’s polystyrene production technology, the production capacity structure of the polystyrene industry has been continuously optimized, and high impact polystyrene (HIPS) ) The market continues to develop and production capacity continues to grow. According to the“China High Impact Polystyrene (HIPS) Industry Market Monitoring and Future Development Prospects Research Report 2022-2026” released by the Industrial Research CenterIn 2021, China’s high-impact polystyrene (HIPS) production capacity will reach 1.56 million tons.

High-impact polystyrene has high production technical barriers. The number of companies that can produce high-impact polystyrene products in my country is smaller than that of general-purpose polystyrene. However, with the expansion of market demand, the number of high-impact polystyrene products in my country has increased. New companies are constantly entering the stamped polystyrene field, and the level of market competition is increasing day by day. At present, the main domestic high-impact polystyrene suppliers include Shanghai Secco Petrochemical Co., Ltd., Xinghui Environmental Protection Materials Co., Ltd., Zhenjiang Chimei Chemical Co., Ltd., Yangzi Petrochemical-BASF Co., Ltd., etc.

Industry researchers say high-impact polystyrene (HIPS) contains rubber that strengthens and improves barrier properties and is opaque. It is easy to thermoform and has a wide range of applications. The end products are closely related to consumers’ daily lives. High-impact polystyrene is a new national strategic industry new material and is a typical application material for refrigerated dairy product packaging. With the upgrading of domestic consumption and the deepening of the concept of green and environmental protection, the demand for high-impact polystyrene to replace traditional materials is becoming increasingly urgent, the trend is gradually becoming clear, and the market prospects are broad.
