In May 2011, our company undertook the engineering general contracting work for the first phase of the 30,000-ton/year trans-isoprene rubber industrial plant of Qingdao Taidai New Materials Co., Ltd. In March 2013, the project was completed and accepted. This plant is the world's first 10,000-ton trans-isoprene rubber plant and also the first industrial-scale plant in China, filling the gap in domestic engineering design and construction.
