Precipitated silica market: We have learned in August that soda ash and sulfuric acid have surged by 30%-80%. Entering September, these two major materials are still rising steadily. This week, the price of light alkali is about CYN 3100 / ton, and that of heavy alkali is about CYN 3300  / ton. At present, the operating rate has increased, but there are many orders owed. The spot supply is still in short supply. According to the forecast of some precipitated silica companies, soda ash is expected to maintain a high level of operation throughout September. From this point of view, the price increase of precipitated silica is expected to be implemented. At present, the price of silica mainly for tires has already been raised by CYN 500/ton. Silica for silicone rubber has different inventories of sodium silicate from different manufacturers, and at the same time, in order to maintain customers, the price increase is not uniform. However, under the influence of the rising trend, precipitated silica manufacturers have recently received orders satisfactorily, and most manufacturers have placed orders until the end of September.

Fumed silica market: on the raw material side, the price of monomethyltrichlorosilane in Shandong rose another CYN: 100 to 2950 /ton, and the price of silicon tetrachloride continued to consolidate. Cost support still exists, but the fumed silica market is still constrained by demand. At present, the high-end quotation of 200-meter fumed silica is CYN 24,000-26,000 /ton.Specifically, downstream silicone rubber companies have performed outstandingly recently, and they are good at purchasing gas silicon, but now they have entered a stable period, and stocking continues to be rigid. The atmosphere of competition for orders in gas silicon companies is still fierce.
