On January 6, PetroChina Northwest Sales Company raised the ex-factory price of emulsion styrene-butadiene rubber by 200 yuan/ton. Currently, the prices of Lanhua 1502E and 1500E stand at 11,700 yuan/ton. PriceSeek's analysis of styrene-butadiene rubber indicates a long-short score of 1.5. The 200 yuan/ton increase in ex-factory prices suggests that suppliers are proactively raising prices, likely due to rising raw material costs or strengthening demand, which constitutes a significant positive factor for spot prices. This upward adjustment will bolster market bullish sentiment, driving a short-term upward trend in the spot price of styrene-butadiene rubber, with an expected potential increase of 5–10%.
