Polyethylene Rises Under Pressure and Retreats from Weekly Highs

ECHEMI 2026-07-18

July 17th News Curve Comparison Chart

This week, polyethylene prices first surged rapidly and then slightly declined after reaching a peak. According to Spotcom data: the average price of LLDPE (7042) on July 13 was 7,835 CNY/ton, and by July 17, it had risen to 8,350 CNY/ton, an increase of 6.57%. The average price of LDPE (2426H) on July 13 was 10,000 CNY/ton, and by July 17, it had increased to 10,466 CNY/ton, a rise of 4.67%. The average price of HDPE (5000S) on July 13 was 10,512 CNY/ton, and by July 17, it had gone up to 10,762 CNY/ton, an increase of 2.38%.

International crude oil prices have continued to strengthen, raising the production costs for petrochemicals and providing a solid bottom support for polyethylene. The increase in costs has led to consecutive adjustments in the factory prices of petrochemicals, with traders following suit by increasing their selling prices, directly driving a rapid rise in prices at the beginning of the week.

Chinese petrochemical plants are undergoing concentrated maintenance, leading to a tightening of available spot goods in the market. Port inventory continues to decrease, and the tight supply of spot goods is boosting market sentiment for price increases, prompting traders to actively raise prices.

The downstream film and filament industries in China are in the traditional low-demand season. After the continuous rise in raw material prices, the cost pressure on factories has increased, leading to overall low production levels, with only a small amount of procurement to meet essential needs. High-priced goods are experiencing poor sales, and there is a lack of actual buying interest from end-users.

In the short term, polyethylene as a whole continues to exhibit a weak, oscillating pattern at relatively high levels, with upward price increases facing constraints.
