Reply to 8# lxq700918: It’s hard to say anything about investment; if starting from scratch with nothing established yet, the cost for the main equipment will be around 1.3 billion. This amount can increase depending on the technical processes chosen. The supporting facilities will cost around 600 million yuan (this is an estimate). The construction period is around 24 months, depending mainly on the capabilities of the design institute and the delivery time of imported equipment. Shanghai Lanshin’s investment should now exceed 1.8 billion.

China Yuntianhua Group, China Nantong PTM Engineering Plastics Company, China Zhangjiagang DuPont, Asahi Kasei Corporation, China National Chemical Corporation Shanghai Lanxing Company, Henan Yongmei Group, Tianjin Bohai Chemical Group, Shenhua Ningmei Group, Xinjiang United Chemical Group, Chongqing Changshou Yuntianhua Co., Ltd., and Inner Mongolia Tianye Chemical Company – the first five are already in operation, while the latter ones are under construction.
