Polydimethylsiloxane (PDMS) is a polymer characterized by the presence of silicon and oxygen elements in its structure. The molecules of this polymer are linked by silicon-oxygen bonds, forming a siloxane chain. It exhibits excellent chemical stability, thermal stability, and biocompatibility. Due to its unique chemical structure, PDMS finds widespread applications across various fields.

      The position of China in the chemical industry is quite significant, and polydimethylsiloxane (PDMS) is an important product in the chemical sector. As one of the world's largest producers and consumers of chemicals, China holds a crucial international position in the PDMS industry.

      According to customs data, the trade value of polydimethylsiloxane (PDMS) has shown an increasing trend from 2018 to 2022. The trade value has risen from $1,101,402,793 to $2,049,345,969 during this period. In terms of quantity, there is also an upward trend, increasing from 263,771,158 kilograms in 2018 to 453,024,063 kilograms in 2022. Although both trade value and quantity experienced some fluctuations each year, there was a significant growth in both aspects in 2021, with the trade value increasing by 119.26% compared to the previous year. However, from 2022 to 2023, both trade value and quantity have shown a declining trend.

       The unusual growth in 2021 is somewhat related to the global pandemic. The outbreak of the pandemic in early 2020 led to disruptions in the global supply chain, a decrease in demand, and other issues. However, in 2021, some countries and regions began implementing vaccine campaigns, resulting in economic recovery and prompting trade growth. Additionally, certain industries may have experienced rapid demand growth after the pandemic. Subsequently, with the global economic recovery, market demand stabilized, and compared to the exceptional growth in 2021, a declining trend started to emerge in 2022. Of course, the downward trend in the past two years may also be influenced by factors such as geopolitical tensions (such as the Russia-Ukraine conflict), global economic conditions, and fluctuations in energy prices.

      The significance of polydimethylsiloxane (PDMS) lies in its versatility and wide applicability, making it a key material in various industries. For instance, its excellent biocompatibility makes it suitable for manufacturing a variety of medical devices and implants in the healthcare sector, such as catheters, sealing materials, and artificial organs. Due to the unique structure of the siloxane chain, PDMS also exhibits outstanding lubrication properties, making it widely used as a lubricant in mechanical equipment, automotive components, and industrial machinery. Additionally, PDMS serves as a sealing material to prevent the leakage of liquids and gases. Its high temperature resistance and chemical stability further contribute to its importance in the manufacturing of electronic components.

       Overall, the foreign trade prospects of polydimethylsiloxane (PDMS) depend on the combined impact of various factors. For international trade professionals, it is crucial to have an understanding of global market dynamics, industry trends, and relevant policies.
