The lowest price of 20 12 ethylene glycol appeared at the beginning of June, which was 6275 yuan/ton, and the highest price appeared at the end of the year, which was 9065 yuan/ton, with a spread of 2790 yuan/ton. The lowest price of ethylene glycol in 20 13 years appeared at the beginning of June, which was 6855 yuan/ton, and the highest price appeared at the beginning of the year, which was 9 125 yuan/ton, and the spread narrowed to 2270 yuan/ton. In 20 14, the lowest price of ethylene glycol appeared in the middle of 10, which was 5640 yuan/ton, and the highest price appeared in June, which was 7585 yuan/ton, and the spread was 1945 yuan/ton.

Price comparison between ethylene glycol and related varieties
1, raw material ethylene market
As a direct raw material for the production of ethylene glycol, the price trend of ethylene has an obvious guiding effect on the trend of ethylene glycol, and the correlation between the price trend of ethylene and ethylene glycol is as high as 74% from 20 13 to 20 15. From 20 13 to 20 15, the fluctuation of raw material ethylene will form a strong early guide to the trend of ethylene glycol market, and the trend synchronization of key points of the two products is more obvious.
However, from 20 16, the correlation between them weakened, and the correlation coefficient was only 39.48%. 20 17, and the correlation between them is 32.44%. This is because although ethylene is the direct upstream raw material of ethylene glycol from the process route, at present, the production enterprises are basically integrated devices of crude oil, naphtha, ethylene and ethylene glycol, and the production enterprises do not produce ethylene glycol separately. At present, the overall profit level of the industry is relatively high, so the correlation with the trend of direct raw material ethylene is not particularly obvious.
2, Jiangsu and Zhejiang polyester chip market
In recent two years, ethylene glycol and downstream polyester products have a very high convergence in price trend. Most of the time, the price trend is dominated by raw materials, and downstream products actively follow up. In recent years, China's polyester production capacity has been released rapidly, forming a surplus pattern rapidly, so there is basically no obvious promotion from downstream after 20 13. In the peak season, ethylene glycol can quickly smell the signs of improvement in downstream production and take the initiative to form an upward trend. In the fourth quarter of 20 14, the two main raw materials, ethylene glycol and PTA, fell deeply, which brought huge cost dividends to downstream polyester production. Downstream production turned from loss to profit, production enthusiasm increased, raw materials were consumed quickly, and the price of ethylene glycol was supported again. Judging from the trend of 20 15-20 17, the traditional peak season of downstream polyester products still plays a driving role in the ethylene glycol market. In the first half of the year, the factories driven by the traditional peak season of downstream polyester just need to stock up, which has a good support for the raw material market. In the second half of the year, the driving force from the downstream of the ethylene glycol market gradually subsided, and the guidance of crude oil and macroeconomics became the main judgment of the market trend.
