Less than a month apart! Yangzi Petrochemical has experienced another flash explosion accident! 2 deaths and 3 injuries! On June 24, 2026, Sinopec Yangtze Petrochemical experienced another accident during maintenance and repair. The solvent recovery tower of its aromatics unit No.2 reforming unit experienced a flash explosion during the reinstallation of the tray, causing the tray to collapse and resulting in 2 deaths and 3 injuries. The specific cause is still under further investigation. Readers are advised to pay attention to the official announcement. And less than a month ago, the company had a serious accident. On May 29, 2026, a flash fire accident occurred during the maintenance operation of the ethylene unit at Sinopec Yangzi Petrochemical Company, resulting in the death of four workers. The direct cause of the accident was the incomplete replacement of residual combustible gas in the pipeline, which leaked and caused flash fire when encountering cutting sparks. At present, the inspection and maintenance operations of chemical enterprises in China are at a high level, coupled with rising temperatures, and the situation of chemical safety production is severe and complex. All relevant enterprises in various regions should conscientiously carry out accident prevention work: firstly, carry out risk identification of inspection and maintenance operation conditions, thoroughly return, clean, blow and replace hazardous chemical systems, and strictly implement equipment handover condition confirmation. Secondly, in accordance with the safety regulations for maintenance operations, cross operations should be strictly controlled in the same maintenance area. If cross operations are necessary, the responsible person for on-site coordination should be clearly defined to prevent the accumulation and transmission of risks. The third is to strictly implement the relevant requirements of GB 30871, conscientiously fulfill the approval of special operations and comprehensively identify safety risks, strengthen contractor management, and truly implement operational requirements to the front line of positions.
Market Overview: Last week, the domestic DMC market continued to decline. On the raw material side, metal silicon is operating weakly and steadily, while methanol prices continue to decline, and cost support is further weakening. The inventory pressure of local individual factories has increased, and the overall actual transaction volume of the industry is limited due to price reductions and discounts to promote shipments. The current mainstream quotation for DMC is 14800 yuan/ton, with an actual average transaction price of around 13800 yuan/ton. Last week, the prices of DMC raw materials continued to decline, with companies offering high prices for 107 rubber, raw rubber, mixed rubber, and silicone oil products lowering their prices. As a result, the overall market transaction price center shifted downwards. At present, weak market demand is suppressing procurement, and there is still downward pressure on the prices of various silicone products in the short term, which is expected to maintain a weak operation.
Overview: Last week, the domestic market for gas-phase white carbon black remained stable overall. The supply of methyl trichlorosilane has slightly tightened, with a slight increase in market prices, providing some support for the cost of gas-phase white carbon black; The price of silicon tetrachloride is still in a high and stable state, and the overall support on the raw material side is still relatively obvious.
The downstream demand side continues to show weak and stable performance, and the downstream silicone rubber and related products industry has entered the traditional off-season of demand. Market procurement is still mainly based on rigid demand replenishment, with limited overall trading volume and increased market wait-and-see. Overall, the current market cost support is still present, but the demand side suppression is more obvious, and the game pattern between supply and demand continues. It is expected that the gas-phase white carbon black market will continue to operate weakly and steadily in the short term.
