According to the monitoring of the business agency, the price of NBR first rose and then fell in May, with the price at the beginning of the month at 13700 yuan / ton, and then rose to 14000 yuan / ton, the highest point of the month, and then fell to 13900 yuan / ton at the end of the month, with a slight increase of 1.46% compared with the beginning of the month as a whole at the end of the month. On May 30, the NBR commodity index was 65.46, flat with yesterday, 47.07% lower than 123.67 (2017-02-20), the highest point in the cycle, and 26.81% higher than 51.62, the lowest point on March 8, 2016. (Note: cycle refers to 2012-09-01 to now).

The rise of raw material price supported the NBR. Butadiene prices fell first and then rose, with an overall increase of 7.56%; acrylonitrile prices rose sharply, with an overall increase of 17.19%. According to the monitoring of the business association, the domestic butadiene price at the beginning of the month was 3890 yuan / ton, rising to 4345 yuan / ton in the middle of the month, falling to 4184 yuan / ton at the end of the month, up 7.56% on the whole at the end of the month compared with the beginning of the month; the factory price of domestic acrylonitrile Shanghai Secco was increased from 6400 yuan / ton at the beginning of the month to 7500 yuan / ton at the end of the month, up 17.19% on the whole.

The supply of NBR in May was lower than that in April. At the end of April, Lanzhou Petrochemical Company shut down and overhauled its 50000t / a NBR plant, which lasted until the middle of May. The supply of some NBR brands decreased, and the inventory consumption led to the upward trend of NBR market to a certain extent. At the end of May, Lanhua had 15000 T / a nitrile plant shutdown for maintenance, but other units in the industry started normally, and the supply side increased at the end of the month. In addition, at the end of the month, the downstream mainly consumed the early-stage inventory, most of the transactions were small orders, and the demand for nitrile rubber was slightly negative.

Aftermarket forecast: business analysts believe that in the later stage, on the one hand, raw materials have rebounded to a certain extent, on the other hand, it is unlikely to rise sharply again on this basis. In addition, after the early preparation of goods in the downstream, the transaction in the later stage will be dominated by small orders. In a comprehensive view, the negative effect on NBR is obvious. It is predicted that if there is no other device to stop for maintenance in the later stage, the possibility of weakening vibration of NBR will be greater.
