Guangzhou Chemical Market Consolidation Overall Less Significantly Lower
In the second half of September, the market experienced a slight decline in demand due to the influence of the National Day holiday. As a result, prices in Guangzhou also showed a minor downward trend, although the overall rate of decrease was not significant. Market participants expect that after the long holiday, demand in the chemical sector will gradually recover, but the increase is expected to be moderate, which would have a limited impact on market prices.
Pure benzene prices on the external market have been rising steadily, but domestic market pressure remains high. With the influence of the long vacation, demand has dropped slightly, leading to a small price decline. The current price range for pure benzene is between RMB 7,200 and RMB 7,500.
Toluene prices were supported by an increase in the quoted price of toluene on the external market. Despite a temporary drop in demand due to the holiday, the external market's strong pricing has provided support to domestic toluene prices. The current market price for toluene has risen to 7,500 yuan, up by 300 yuan from the previous period.
Xylene prices have increased due to volatility in crude oil prices and higher external market quotations. The xylene market has seen a rally, with current prices reaching 7,500 yuan.
Styrene prices remained stable at around 11,000 yuan, mainly due to weak demand. Phthalic anhydride prices also fell as demand decreased, and the Guangzhou market saw a slight price drop due to weak demand and reduced trader confidence post-holiday. The current market price for domestic phthalic anhydride is 8,150 yuan, while imported grades are priced at 8,250 yuan.
Methanol prices have been steadily increasing due to rising downstream demand and higher external market quotes. The current market price for methanol is 2,450 yuan.
Ethylene glycol prices declined due to reduced downstream demand. The external market saw lower prices, and the Guangzhou market also experienced a slight drop, with current prices at 8,350 yuan.
The butanol market remains balanced, with manufacturers facing little shipping pressure. Factory prices remain stable, and the market price is currently between 9,500 and 9,600 yuan.
Acetone prices have slightly declined due to abundant supply and low downstream demand. Current prices are between 6,800 and 7,000 yuan.
Dioctyl ester prices fell due to reduced demand during the holiday and a slight decline in raw material prices. The current market price for dioctyl ester is 10,700 yuan.
Ethyl acetate prices rose sharply due to an increase in acetic acid prices. The current market price is between 8,300 and 8,400 yuan, up 600 yuan from the previous period.
Butyl acetate prices continued to rise, though the increase was relatively modest. The current market price is between 10,600 and 10,700 yuan, up 300 yuan from the previous period.
Low-density polyethylene prices remained stable despite weak downstream demand and high inventory levels. The current price range for thin film materials is between 11,100 and 11,500 yuan.
High-density polyethylene prices remained stable, although the market was dull due to soft demand. The current market price for drawing materials is between 10,500 and 10,700 yuan, and injection plastics are priced between 10,500 and 10,600 yuan.
Polypropylene prices continued to decline slightly due to weak demand and increased inventory. The current price range for film materials is between 11,000 and 11,100 yuan, and injection plastics are between 10,850 and 11,150 yuan.
PVC prices fell as supply increased and demand remained sluggish. Traders lowered prices to reduce inventory pressure. The current price for calcium carbide is 6,700 yuan, and vinyl materials are priced at 7,000 yuan.
ABS ex-factory prices remained stable, with market prices fluctuating around previous levels. The current market price for general-grade products is between 14,400 and 14,700 yuan.
Polystyrene demand has not shown significant improvement, and traders are panicking due to falling styrene prices. Although shipment intentions are strong, market price changes remain limited. The current GPPS market price is between 10,800 and 11,800 yuan.
Natural rubber prices remain high, with standard rubber SCR still trading at 16,600 to 16,800 yuan. Increased purchasing activity due to futures market fluctuations has boosted market sentiment.
The SBR market showed a weak trend, with prices slightly declining due to unsatisfactory demand. The current price for rosin-type rubber 1502 is 14,900 to 15,000 yuan, down 100 yuan from the previous period.
Despite a shortage of butadiene rubber, market prices have slightly declined due to flat demand. The current trading price is between 15,800 and 15,900 yuan.
