February 6th news: Recently, the 40,000-ton-per-year ultra-high molecular weight polyethylene plant invested and constructed by Chengzhi Co., Ltd. achieved a successful one-time trial operation with stable operation and the smooth production of uniformly sized, high-quality products. Chempricehub analysis of polyethylene, long-short score: -1. The successful one-time trial operation of Chengzhi Co., Ltd.'s 40,000-ton-per-year ultra-high molecular weight polyethylene plant may exert downward pressure on polyethylene spot prices, as the increase in market supply will exacerbate the loose supply-demand balance. Meanwhile, polyethylene futures data indicate a general decline in the prices of recent main contracts (e.g., contract 2605 settlement price at 6,823 yuan/ton, down 79 points). The release of new production capacity may reinforce the downward trend in futures prices, with overall bearish implications being significant.
