At present, the pure alkali market continues to operate at a high level, with relatively tight spot supply and strong price support. Currently, the mainstream price of light alkali in China is between 3050-3150 yuan/ton, and the quotation for heavy alkali is between 3300-3400 yuan/ton. The cost side has been significantly increasing for nearly two months, and precipitated white carbon black finally saw a unified price increase of 700 in early September! In terms of demand, blended rubber has gradually accepted the fact that the price of white carbon black has increased. However, according to our understanding, manufacturers are still cautious in increasing the actual transaction volume of core large customers, and most orders are limited in quantity to see who will take the lead. This week, the quotation for precipitated silica used in silicone rubber is 7300~7500 yuan/ton. In the future, the price of soda ash is expected to continue to reach a high level, and there is a high probability that the increase in silica will achieve a landing transaction!
