The hottest isoprene rubber industry is booming

  • Detail

Isoprene rubber industry is booming. Since such ideas of customers often force domestic experimental machine enterprises to engage in "price war", since Guangdong Maoming Luhua Chemical Co., Ltd. completed and put into operation the first set of industrial isoprene rubber production plant in China in 2010, enterprises have set off a climax of isoprene rubber project investment and construction. Therefore, at the 2011 national synthetic rubber information and application technology seminar hosted by the national rubber industry information center and the rubber professional committee of the Chinese society of chemical industry on August 30, the domestic isoprene rubber project and its application in tires became a hot spot in the industry. Many industry experts agree that with the gradual development and maturity of the market, it is expected that the domestic isoprene rubber industry will continue to be hot

According to the statistics of the International Association of synthetic rubber producers, the production capacity of the world's isoprene rubber producers, the United States, the Netherlands, Russia, South Africa and Japan in 2010 was 90000 tons, 15000 tons, 512000 tons, 4000 tons and 86000 tons respectively. Under the current situation of rising natural rubber prices, it is expected that the operating rate of foreign isoprene rubber production units will be greatly increased. However, except China and Japan, there is no news of new expansion units in other countries. It is expected that the production of foreign isoprene rubber will remain stable for some time in the future, and small-scale expansion projects may be completed

however, the enthusiasm for launching isoprene rubber in China is very high. According to incomplete statistics of stretching, the annual production capacity of isoprene rubber that has been built and under construction in China will reach 215000 tons from 2010 to 2012. In addition to the 15000 T/a project of Maoming Luhua Chemical Co., Ltd. and the 30000 T/a project of Qingdao ICOS Co., Ltd., which have been completed and put into operation, there are also 50000 T/a projects of Liaoning Panjin Zhenao Chemical Co., Ltd., 30000 T/a of phase I of Qingdao Dipai new materials Co., Ltd., 50000 T/a of Shandong Zibo Luhua and 40000 t/a of Qingdao ICOS (Fushun) Co., Ltd. which will be completed and put into operation in 2012 with the support of a series of preferential policies. Therefore, the growth of world isoprene rubber production capacity in the next few years will mainly come from China

great potential for alternative application

the domestic isoprene rubber produced at present is in short supply in the market. Many industry experts believe that the strong market demand is one of the main reasons for the hot investment. Yangxiuxia, senior engineer of China Stone army band playing the National Anthem of China and Mongolia, believes that China's isoprene rubber demand will increase at an average annual rate of 34%, and the demand will reach about 300000 tons in 2015. Assuming that 20% of the current consumption of natural rubber is replaced by isoprene rubber, based on the domestic consumption of 3.1 million tons of natural rubber in 2010, 620000 tons of isoprene rubber will be consumed. It is estimated that China's demand for natural rubber will reach about 4.8 million tons by 2015, so the demand for isoprene rubber will be about 960000 tons. This shows the great potential of China's isoprene rubber market

sufficient and guaranteed raw materials

with the rapid development of China's ethylene industry, the amount of C5 resources, a by-product in the ethylene production process, continues to increase, thus increasing the output of monomer isoprene, and ensuring the supply of raw materials for isoprene rubber. At present, China's cracking C5 production enterprises mainly include Shanghai Petrochemical, Shandong Yuhuang chemical, Zibo Qilu ethylene Luhua chemical, Puyang Xinyu petrochemical and Zhejiang Ningbo jinheide banner chemical, with a total annual capacity of 78.5 tons, including about 157000 tons of isoprene. In the next few years, Nanjing Jinpu Petrochemical Co., Ltd., PetroChina, Beijing Yanshan Petrochemical Co., Ltd. and Lanzhou Petrochemical Co., Ltd., with a total of 760000 T/A, will be completed and put into operation, which will fully meet the demand for isoprene in China. The solution of the bottleneck problem of raw materials has accelerated the launching and development of domestic isoprene rubber projects

Professor chenzhihong of Beijing rubber industry research and Design Institute pointed out that, impacted by the world's two oil crises, the improvement of natural rubber technology and the expansion of planting area, the United States shut down the isoprene rubber production units of shell and Goodrich in 1973 and 1978, while Italy shut down its isoprene rubber unit in 1980 and dismantled it in 1985, France stopped production and dismantled it in 1986, and some planned production capacity was postponed or cancelled one after another. Isoprene rubber industry and downstream industries under construction must learn lessons and pay attention to resource utilization

he suggested that by 2015, 20% isoprene rubber should be used to replace natural rubber in the tread and carcass of bias ply tires; For radial truck tire, 100% isoprene rubber was used to replace natural rubber in bead steel wire rubber and rubber core rubber; In terms of semi steel passenger radial tire, 70% isoprene rubber is used to replace natural rubber in polyester cord rubber, so that isoprene rubber tire can be reasonably used in tire industry
