April 15 (Reuters) - On April 15, Sinopec Zhongke Petrochemical reduced its diethylene glycol (DEG) offer by 250 yuan per ton, with the premium-grade ex-works self-pickup price set at 7,650 yuan per ton. Chempricehub's analysis of DEG shows a bearish score of -1. The price cut by Sinopec Zhongke Petrochemical, lowering DEG offers by 250 yuan per ton to 7,650 yuan per ton, indicates increased supply pressure or weak demand in the spot market, directly exerting downward pressure on spot prices. This significant reduction (approximately 3.3%) reflects sellers' proactive price cuts to stimulate sales, potentially triggering a chain reaction in the market and further weighing on spot prices. In the short term, downstream procurement may become more cautious, limiting the room for price rebounds.
