Shandong butyl inner tube factory with 1675N butyl rubber

China butyl rubber research and development began in the 1960s, and established a pilot production plant, due to various reasons to stop. In 1999, the Beijing Yanshan Petrochemical Company Synthetic Rubber Factory introduction of Italy PI's technology to build China's only set of 30kt / a butyl rubber production plant. The device is capable of producing ⅡR1751, ⅡR1751F and ⅡR0745 three grades of regular butyl rubber, which belongs to the inner tube ⅡR1751 class products, medium without saturation, high Mooney viscosity, the equivalent of Exxon's 268, Bayer's 301 and Russia BK1675N product brands, primarily for the manufacture of tire inner tubes, tire curing bladders and water and other products; IR1751F food, pharmaceutical grade products, medium without saturation, high Mooney viscosity can be used in chewing gum base material and medical cork production; ⅡR0745 is insulation materials, sealing materials and film grade products, low unsaturation, low Mooney viscosity, mainly for the production of electrical insulation and the cable head film. The first two years, because of technology, equipment and other aspects of continuous and stable operation of the device is difficult, low operating rate, low rate of qualified products, raw material consumption, power consumption and high cost. 2000 and 2001 were only 4.055kt as well as annual and 4.190kt. After nearly two years of technical research, plant health has improved a great extent, production increased year by year, production in 2002 reached 21.545kt, which was 84.7 percent qualified products, output in 2003 and further increased to 27kt, including product qualification rate reached 95.4 percent.
