Polystyrene (PS for short) is a thermoplastic resin polymerized from styrene as the main raw material. Polystyrene is mainly divided into general-purpose polystyrene (GPPS), high-impact polystyrene (HIPS) and expanded polystyrene (EPS), which is commonly known as general purpose polystyrene through benzene, the appearance of colorless, odorless, tasteless and shiny, transparent bead or granular solid. GPPS has the characteristics of high transparency, good gloss, easy processing, good dimensional stability and so on. It is widely used in consumer goods, food packaging, stationery, electronic appliances and other fields.
According to the "2021-2026 China General-Purpose Polystyrene (GPPS) Industry Market In-depth research and Development Prospect Forecast report" released by Siworld Industry Research Center, in recent years, thanks to the continuous release of market demand, the global GPPS market scale has gradually expanded, the development of 2020, the market scale has reached 62.5 billion yuan.At present, the global GPPS market has entered the mature stage, and the growth rate of the GPPS market will slow down in the future. It is estimated that the global GPPS market will maintain a low growth trend with a compound annual growth rate of 0.8% in 2021-2025.
