Summary: On April 19, 2026, D4 quotations rise in line with market trends, and its role as an alternative to DMC is further highlighted, with a significant increase in market transaction volume in major consumption regions.
BEIJING, April 19, 2026 — D4 (Octamethylcyclotetrasiloxane) is an important alternative intermediate for DMC in the silicone production process. With more monomer factories suspending DMC spot quotations, D4’s market demand has increased significantly, driving its price to rise moderately.
On April 19, 2026, the domestic mainstream quotation of D4 ranges from 14,700–15,400 yuan/ton, up 100 yuan/ton from the previous day. The price increase is mainly due to the tight supply of DMC and the surge in alternative demand. In East China and South China, the main consumption regions of DMC and D4, the transaction volume of D4 has increased notably compared with the previous day, with downstream deep-processing enterprises actively purchasing D4 to replace DMC and ensure normal production.
Industry analysts point out that as long as the tight supply of DMC persists, D4’s alternative role will continue to be highlighted, and its price may maintain a synchronized upward trend with DMC in the short term. However, with the gradual recovery of DMC supply in the later period, the price gap between D4 and DMC is expected to narrow.
