Development Trend Of Chloroprene Rubber
Jan 05, 2018

After years of development, China's neoprene production capacity has reached 83,000 tons, coupled with the future of new or expanded, production capacity will be excessive. Shanxi Synthetic Rubber Group staff said that due to weak downstream demand, enterprise devices are half load operation. That because the future competition will be more intense, new devices should be cautious, the relevant manufacturers can consider to open up foreign markets.

Footwear and Construction field adhesive is the largest application of neoprene in China, accounting for about 60% of total consumption, followed by industrial rubber products, accounting for about 30% of total consumption, and about 10% for wire and cable and other fields. From the geographical distribution, South China, east China, the largest consumption, accounting for about 65% of the total consumption of the country, north and central China accounted for 25% of the other areas accounted for 10%. As the global economic trend is still in recession, the development of China's relevant industries will also slow down, coupled with EPDM and other products such as substitution, the domestic demand for neoprene will not be a big increase. By 2015, the total consumption of neoprene in China is only 70,000-75,000 tons. Consumer demand growth is slow, then the corresponding production market situation?

The research and development of neoprene in China began in the 1950s. Changchun Institute of Applied Chemistry, Chinese Academy of Sciences first carried out the study of calcium carbide acetylene synthesis of neoprene, 1953 in Changchun completed 450kg/month test equipment; In 1956, Chongqing Longevity Chemical plant used the above-mentioned scientific research and the former Soviet Union technology to build 2000 tons/year production device, in 1958; 1965-1966, our country successively in Shanxi synthetic rubber group, Shandong Qingdao Chemical Plant has built the carbide acetylene method production device, the production capacity each is 2500 tons/year, after the treatment all uses the electrolyte condensation technology; In 1987, the 3 plants successively introduced the freezing condensation technology, carried on the reconstruction and expansion of the equipment, Qingdao Chemical plant after the expansion of the production capacity reached 10,000 tons/year, but in the late 1990s production transition; In 2007, Shanxi Synthetic Rubber Group Co., Ltd. and Armenia in accordance with the company began a joint venture to build 30,000 tons/year of neoprene production equipment, after several years of efforts, The device was completed and put into operation in December 2009. By the end of 2010, China's total production capacity of neoprene reached 83,000 tons, accounting for about 20.96% of the total production capacity of the world's neoprene. Among them, Shanxi synthetic rubber Group production capacity of 55,000 tons/year, accounting for about 66.27% of total production capacity, Chongqing longevity Chemical Company's production capacity of 28,000 tons/year, accounting for about 33.73% of the total production capacity.
