Summary: On April 19, 2026, industrial silicon prices continue their mild upward trend, supported by tight quartz sand supply and strong demand from silicone monomer factories, with trading volume increasing significantly.
BEIJING, April 19, 2026 — As the core upstream raw material for silicone monomer synthesis, industrial silicon’s price trend directly affects the cost of the entire silicone industry chain. On April 19, 2026, the main futures contract of industrial silicon (SI) on the Zhengzhou Commodity Exchange closed at 8,564 yuan/ton, an increase of 60 yuan/ton or 0.71% compared with the previous trading day. The trading volume reached 62,350 lots, a day-on-day increase of 8.32%, reflecting strong market activity.
The upward momentum of industrial silicon prices is mainly driven by two core factors. First, the supply of quartz sand, a key raw material for industrial silicon production, is tight in major producing areas such as Sichuan and Yunnan. Strict environmental protection supervision and limited mining quotas have restricted the output of quartz sand, leading to an increase in the production cost of industrial silicon enterprises. Second, downstream silicone monomer factories maintain a stable operating rate of around 65%, with strong demand for industrial silicon procurement to ensure the continuity of their own production, forming a strong pull on industrial silicon prices.
Industry insiders predict that in the short term, the supply of industrial silicon will remain tight, and the price may continue its mild upward trend, which will further affect the cost of downstream silicone products.
