In 2021, the domestic rubber grade silica market continued its upward trend. In January, the price was 4733.33 yuan / ton, and as of December 30, the price was 6750 yuan / ton, an increase of 42.61% for the whole year, reaching 2000 yuan / ton. In the first half of 2021, the silica market was tepid and operated steadily for several months until June. After opening in the second half of the year, the silica showed a narrow upward trend, The focus of negotiation has been high for several consecutive months, and the supply side is tight. The price has stabilized again in mid November. The lowest price of white carbon black in 2021 is 4733.33 yuan / ton in January, and the highest price in early November is 6875 yuan / ton.

In the first half of 2021, the white carbon black market is mainly dominated by stable transportation, with a large number of contract orders, most of which are just in need of procurement. The procurement atmosphere is flat and the number of new orders is limited. Near the Spring Festival in 2021, the white carbon black shipment is slow, the negotiation atmosphere is general, the merchants are cautious in taking goods, the white carbon black was sorted out in a narrow range in the first quarter, and the price remained at about 4750 yuan / ton, entering the second quarter, The mainstream price of white carbon black remained at 4700-4800 yuan / ton. It was slightly stronger in the second quarter, and the overall price increased by 0.35%. The price fluctuation range of white carbon black in the first half of the year was not very large, and the price has been hovering around 4800. For many years, the tire industry has relied on precipitated white carbon black as an important reinforcing agent in rubber to improve the wet skid resistance of tires, Steering controllability and wear resistance. Generally speaking, white carbon black plays an important role in vehicle safety and fuel consumption, while the high demand for new energy vehicles does not promote the market situation of white carbon black.

White carbon black plays an important role in the manufacturing of automobile tires. As we all know, tires have wear resistance, safety, environmental protection and clean oil performance. In 1992, French Michelin developed the world’s first “green tire” filled with a large amount of white carbon black, which significantly improved the wet and skid resistance of tires and opened up a new direction of tire research and development, In the past two years, due to the impact of public events, domestic transport vehicles have decreased significantly, the recovery is slow, and the domestic white carbon black market is depressed. There are 23 gas silicon production enterprises in China, and the overall operating rate is affected. Some enterprises have not stopped work, the inventory of operating enterprises is increasing, and the transaction atmosphere is flat. Throughout the first half of 2021, Domestic rubber grade silica showed a stable and weak operation, and the transaction price was basically maintained below the cost line.

Chemical commodity index: on December 30, the chemical index was 1103 points, unchanged from yesterday, decreased by 21.21% compared with the highest point of 1400 points in the cycle (2021-10-23), and increased by 84.45% compared with the lowest point of 598 points on April 8, 2020. (Note: the period refers to the period from December 1, 2011 to now)

In the second half of the year, the trend of silica was strong, and the price had an upward trend. In the third quarter, the overall price of silica increased by 11.97%. By the end of September, the mainstream price of silica was about 5300 yuan / ton. From June to September, the domestic rubber grade silica remained stable and rising, the trend was strong, and the manufacturer’s price increased slightly, From the end of September to October, the mainstream price of white carbon black was about 6800 yuan / ton, and the price increased slightly. The spot in the overall market was tight and slightly relieved. It was mainly for contract customers. In early November, the mainstream price of white carbon black was about 6870 yuan / ton. The trend of white carbon black was stable and the price change was not obvious. As of December 30, the mainstream price of white carbon black was 6750 yuan / ton, The whole second half of the year increased by 43.11%, and the curve showed a continuous upward trend. The overall market operated strongly in the second half of 2021.

Upstream hydrochloric acid: in the first half of 2021, the hydrochloric acid market was in strong shock operation, the price fluctuated, and the overall market price was stable. In the second half of 2021, the trend of the hydrochloric acid market was strong, the shock was upward, some enterprises started maintenance, the supply side was low, and the willingness to purchase was good. The price reached a high point in the middle and early October, and then the price began to decline, which continued from November to December, The trend of hydrochloric acid fluctuated and declined. In December, the market of hydrochloric acid fluctuated and fell first, then rose and then fell. As of December 28, the mainstream price of hydrochloric acid was 320.00 yuan / ton, with insufficient upstream support and insufficient downstream procurement follow-up. It is expected that hydrochloric acid will fluctuate and decline slightly in the near future.

As a reinforcing agent, white carbon black is mainly used in the field of rubber tires, accounting for 70% of the total. White carbon black can reduce tire resistance and resist wet skid. It can be used to produce green tires and replace carbon black for sidewalls. White carbon black is currently in a steady upward trend. With the development of power vehicles, green environmental protection has attracted the attention of the state, and white carbon black, as a representative of green tires, In the near future, I believe I will usher in my own spring.
