Keywords: D4, DMC substitute, silicone intermediate, 14600-15300 yuan/ton, alternative demand
Summary: On April 20, 2026, D4 prices rose slightly to 14,600-15,300 yuan/ton, moving in line with the strong DMC market, and alternative demand continued to increase.
BEIJING, April 20, 2026 — As an important alternative intermediate to DMC, D4 (Octamethylcyclotetrasiloxane) saw a slight price increase on April 20, driven by the tight supply of DMC. The mainstream quotation of D4 was 14,600-15,300 yuan/ton, an increase of 50 yuan/ton from the previous day, and the price gap with DMC remained in a reasonable range.
The price increase is mainly due to the surge in alternative demand: with many DMC manufacturers suspending spot quotations, downstream deep-processing enterprises have increased their purchases of D4 to replace DMC, ensuring normal production. Transactions in East China and South China, the main consumption regions, were active, with strong market acceptance of D4 prices.
Industry analysts pointed out that if DMC remains tight in supply, D4’s alternative role will continue to be highlighted, and its price will maintain a synchronized strong trend with DMC in the short term. The future price trend will depend on the rhythm of DMC quotation resumption and supply recovery.
