Recently, the Weinan Ecology and Environment Bureau issued a public notice regarding the acceptance of the environmental impact assessment report for the industrial demonstration project of polyolefin elastomers (POR) carried out by Shaanxi Shanmei Xiechuangda New Materials Co., Ltd. 　　Shaanxi Shanmei Xiechuangda New Materials Co., Ltd. has built a 100-ton-scale POR industrial testing facility in the Weibei Coal Chemical Industrial Park. The industrial testing of POR has yielded the expected results: the product’s performance parameters meet the required standards, and the process flow for the POR facility has been established. Ethylene propylene diene monomer rubber (EPDM) is one of the main competing materials for polyolefin elastomers (POR). According to test results, compared with EPDM, POR excels in key parameters such as tensile strength and elongation at break; moreover, POR products have a low Mooney viscosity, which completely solves the problem associated with traditional rubbers, namely high molecular weight leading to good performance ； But there is the contradiction of high molecular weight, high Mooney viscosity, and poor processability. 　　Project Overview Project Name: Industrial Demonstration Project for Polyolefin Elastomers (POR) ； 　　Construction location: Weibei Coal Chemical Industrial Park ； 　　Construction unit: Shaanxi Shanmei Xiechuangda New Materials Co., Ltd ； 　　Construction type: New construction ； 　　Construction content and scale: Construction of a production facility capable of producing 35,000 tons per year of polyolefin elastomers (POR) on a dry basis, along with associated facilities ； 　　Total project investment: The total investment amounts to 1,319.67 million yuan, with an environmental protection investment budget of 64.35 million yuan, accounting for 4.88% of the total investment ； 　　Land area: This project is planned to be constructed within the 525.4 mu of land acquired by Xiechuangda New Materials Company ； 　　Labor quota and working system: The labor quota for this project is 190 people, with an annual operating time of 8,000 hours; a four-shift, three-shift operation system is adopted. 　　Product plan: This project is an industrial demonstration project for polyolefin elastomers (POR). The polymerization section is equipped with 2 production lines capable of producing 17,500 tons of POR per year; the overall production capacity is 35,000 tons of polyolefin elastomers (on a dry basis) per year, with 1,600 tons of lower-quality rubber being produced as a by-product (on a dry basis). Products of different grades can be manufactured according to market demand.
