3 • 15 party this year on CCTV exposed, "Kumho Tires use a lot of back mixing" of a ripple. However, the problem is not CCTV Kumho Tire "sudden discovery. "
In 2008, Kumho Tire deep "bulge"incident, in late 2007 to early 2008, Kumho Tire experience "breaking the door"storm. In addition, in 2004 and 2006, Kumho Tire in the United States has also conducted two large-scale recall.
China Quality Association in quality and service vehicles only release specific information website "car people network " of complaints over the past few years, the report, the list has been more Kumho Tires.
The CCTV exposure, the Kumho's first reaction was: "Our use of rubber on the back to develop a scientifically sound production technology standards, and strictly follow the standard production line for production operations, the original film plastic, plastic to add back Ratio is calculated according to weight, not the number of direct proportion, so simple in the video by adding different amount of the compound to determine the Division I violations, is not accurate. "
The actual situation of the international market is a styrene-butadiene rubber plant operating rate of less than 80%, especially around Japan, Korea and Russia, the export surplus to the Chinese market, rubber, tire companies and some multinational joint ventures or wholly-owned plant in China imports the local priority Domestic products (such as Korea, Japan, Taiwan), some larger enterprises tire exports through the export of tires can be imported at preferential prices of rubber raw materials, some to feed the processing trade imported products must be used, so even if the domestic production of styrene butadiene rubber Capacity to meet domestic market demand, annual imports of styrene-butadiene rubber may still be maintained at the level of 15 million tons or even more, so if China wants to consume the excess part of the SBR must increase the proportion of exports. In addition, because of trade barriers to increase exports, improve the resistance to the export of rubber products, rubber and indirect decline in external demand growth.

Isoprene rubber, also known as "synthetic natural rubber"because of the structure closest to the natural rubber, as the best alternative to natural rubber can be widely used in tires, belt, hose and other rubber application products, is a synthetic rubber adhesive seven basic The only species unable to industrial production of plastic types. Isoprene rubber as soon as possible the size of industry, not only can solve the problem of inadequate resources, natural rubber, and the EPA can promote the comprehensive utilization of fractions.
To meet the national demand for the major synthetic rubber, isoprene rubber industry in China to fill the gaps of the Chinese Academy of Sciences, Changchun, Jilin Petrochemical Company of China Petroleum science and technology support projects in the country, "isoprene rubber production technology development, "the support to carry out The isoprene rubber production technology development. Worked in the catalyst, polymerization and condensation process, cis-isoprene rubber content, molecular weight and its distribution has made important breakthroughs in control, first with China's own intellectual property rights, high molecular weight, narrow molecular weight distribution and high-cis 1,4 structure content New rare earth isoprene rubber, and die in 20 liters of continuous polymerization pilot plant tests carried out on a lot to develop pilot products, and successfully applied to all steel truck radial tire.
