  • Yantai Wanhua: Break International Monopoly after 10 Years’ Innovation
  • 2009-01-19
  •     CCTV.com (CCTV News): Yantai Wanhua Polyurethanes Co., Ltd. finally masters the core production technology of the industrial chemical MDI after over 10 years’ exploration, which breaks the technical blockage by international monopolistic companies for 40 years.
         Ding Jiansheng, board chairman of Yantai Wanhua Polyurethanes Co., Ltd.: I declare success of the trail operation of 160,000 tons MDI equipment in feeding and production.
         MDI is the major material for producing polyurethanes. Products like Lycra in cloth, insulating course of the building facades and even the sealing elements for aircrafts are mainly made of it. China firstly introduced in a piece of MDI equipment in 1978, which is a set of outmoded 1960s machine. Moreover, the core technology was not obtained from the import.
         Ding Jiansheng, board chairman of Yantai Wanhua Polyurethanes Co., Ltd.: Due to lacking of proprietary intellectual property rights, the equipment runs poorly. The actual output in the 10 years was far from satisfaction of the designed production capacity.
         On the one hand the output failed to meet the capacity, on the other hand demands for MDI increased rapidly with the development of market in China. Countless plants of down-stream enterprises in Yantai may not get the supply after a week’s waiting.
         Being unable to afford the technical reform cost of over hundreds of million Yuan, Wanhua took another way– exchange the technology with market. However, after Wanhua finished the market research in China with a transnational enterprise, it was dumped.
         Since 1993, Wanhua has been on a thorny road to self-innovation. They carried through more than 10,000 experiments in over 10 years and the modified plans can load several trunks. Now, with the successful operation of 160,000-ton equipment, China’s MDI output would have taken 8% of the global total greatly reducing the import of MDI.
         Ding Jiansheng, board chairman of Yantai Wanhua Polyurethanes Co., Ltd.: Only if we dare to innovate could we win the market with competitive strength to gain the respect of the opponents.
