On March 10th, Hujiao closed at 1105 to close at 35,195 yuan per ton, which was 935 yuan less than the previous day; 1106 was at 34,460 yuan per ton, down 1020 yuan. "About 80% of China's natural rubber is imported, and there is no pricing power or bargaining power in the international market. All are following foreign markets." Deng Yaxi, secretary-general of the China Rubber Industry Association, said that since last year, rubber had been 40,000 yuan/ton. The price stayed on for more than a month, the production cost of tyre enterprises increased sharply, and profitability was greatly weakened.
According to statistics from the China Rubber Industry Association, last year, the domestic tire companies faced a loss of more than 20%. From January to February this year, the loss of tire companies has exceeded 50%. This year, tire companies such as Michelin and Bridgestone have once again announced price increases of 5% to 8% in China's tire matching and replacement market. Domestic tire companies such as Shuangqian and Huanan have again raised prices of domestic tires by 5% to 8%, and exported tires. The price is about 6%.
"It's nice to see that the price of rubber hasn't gone up, and it has even fallen." Deng Yaxi said. Goodyear Chongqing agent Xie Yong said that the drop in the price of natural rubber could ease pressure on manufacturers' production costs and curb the trend of price increase in the tire terminal market.
Raman spectrum indicates the vibration and rotation information of the substance molecules. Different materials have different characteristic of spectrum from other materials--characteristic peak, which provides fingerprint spectrum for the substance characterization and identification. CNI launched Raman Spectrometer with the features of compact design, high resolution, high sensitivity, simple measurement and operation, can replace the old spectrophotometer and widely used in chemical and biological research, environmental science, jewelry appraisal, forensic appraisal, food/drug safety inspection, geological exploration and many other fields.
