In 2023–2024, China, Germany, and the United States were the leading exporters of Poly(dimethylsiloxane), collectively accounting for over 50% of global export value, while the United States, South Korea, and Vietnam emerged as top importers, driven by demand from silicone manufacturing and electronics sectors. Import volumes into Southeast Asia and Mexico have risen steadily since 2022, coinciding with regional diversification in supply chains and moderate upward pressure on Poly(dimethylsiloxane) prices.
Recent Market Dynamics Intelligence
1. Price Trends
- The domestic market price for polydimethylsiloxane (PDMS) has shown a narrow fluctuation trend. In the East China region, the mainstream quoted prices for ordinary viscosity products range from 18,000 to 20,000 RMB/ton, while high-end products are maintained at 22,000 to 25,000 RMB/ton. Compared to the previous week, the price fluctuation amplitude is around ±200 RMB/ton.
- The price trend in the South China region is similar to that in East China, with ordinary viscosity products priced at 18,500 to 20,500 RMB/ton and high-end products at 22,500 to 25,500 RMB/ton. Price fluctuations remain limited.
2. Supply Situation
- The operating rates of domestic PDMS production enterprises are generally stable, with most maintaining normal production levels. Some large-scale enterprises operate their facilities well, with output capable of meeting market demand and accumulating certain inventory.
- Regarding imports, the arrival volume of imported goods has been relatively stable recently, with no significant changes in market supply. However, due to fluctuations in international shipping costs, some importers have made slight adjustments to their quotations, but this has not significantly impacted the overall market supply structure.
3. Demand Situation
- Demand in downstream industries shows divergence. In the daily chemical sector, with the arrival of the summer consumption peak season, the demand for skincare products, shampoos, etc., has increased, leading to a corresponding rise in PDMS procurement volumes, although the overall increase is limited.
- In the construction sector, affected by real estate market regulation policies, the progress of new project starts has slowed down, resulting in a decrease in PDMS demand.
- Demand in the electronics and automotive industries remains stable, with PDMS procurement proceeding as planned without significant fluctuations.
4. Cost Aspects
- The price of the main raw material, metallic silicon, has shown a slight upward trend recently, providing some support for the production costs of PDMS. However, due to sufficient inventory held by production enterprises in the past and cost reductions achieved through process optimization, the cost pressure has not yet been fully transmitted to product prices.
- Energy prices, including electricity and natural gas, remain relatively stable, having a minimal impact on production costs.
Analysis and Judgment
1. Supply-Demand Relationship: The current PDMS market is in a state of basic balance. On the supply side, enterprise operating rates are stable, and imported goods provide timely supplementation. On the demand side, downstream industry demand diverges, but overall demand has not experienced significant fluctuations. This supply-demand structure means there is little momentum for substantial price increases or decreases.
2. Cost Impact: The slight rise in metallic silicon prices provides some support for production costs. However, production enterprises have mitigated cost pressures through various means, making the impact of cost factors on product prices relatively limited.
3. Market Sentiment: Market participants maintain a calm sentiment. Traders and downstream enterprises mostly purchase according to needs, with weak willingness to hoard inventory. Production enterprises also focus on stabilizing production and sales, without significant price adjustments.
Forecast
1. Price Trends: In the short term, PDMS market prices will continue to show a narrow fluctuation trend, with a fluctuation range expected to be within ±300 RMB/ton. If raw material prices continue to rise or downstream demand changes significantly, prices may adjust accordingly, but the possibility of substantial fluctuations remains low.
2. Supply Situation: The operating rates of domestic production enterprises will remain stable, and the arrival volume of imported goods will not see significant increases or decreases. Market supply will remain relatively ample.
3. Demand Situation: Demand in the daily chemical sector is expected to continue growing, but the increase will be limited. Demand in the construction sector is unlikely to improve significantly in the short term. Demand in the electronics and automotive industries will remain stable. Overall demand will maintain current levels, exerting a neutral impact on market prices.
Poly(dimethylsiloxane) (PDMS) is a colorless, transparent, viscous liquid or elastomeric solid at room temperature, depending on molecular weight; it is odorless, non-volatile, and thermally stable, with no sharp melting or boiling point due to its polymeric nature. It is a linear or cyclic organosilicon polymer classified as a silicone fluid or elastomer. PDMS serves primarily as a base polymer in silicone rubber, sealant, and lubricant formulations, and as a key intermediate in the production of crosslinked silicones, silane-modified polymers, and functionalized silicone derivatives. Its principal application areas include personal care products (e.g., conditioners and skin protectants), medical devices (e.g., tubing and implants), industrial coatings, release agents, and antifoaming agents in agrochemicals and pharmaceutical processing.

colourless liquid with a viscosity, The polydimethylsiloxane materials are excellent examples of silicones because of their chemical properties and widespread industrial use. They can be manufactured as gels, resins, fluids, or elastomers, depending on the cross-linking characteristics. Toxicity testing using polydimethylsiloxane compounds on animals has found little, if any, harmful effects associated with chronic exposure. These tests include oral dosing and teratogenicity testing (Cutler et al., 1974; Kennedy et al., 1976). Human health effects associated with silicone implants have been reported. Polydimethylsiloxane is the most prevalent silicone used medically and has been incorporated into many prostheses, including breast implants.
