Core Viewpoint - Evonik has announced the relocation of its liquid polybutadiene POLYVEST® ST-E 60 production to Shanghai, China, emphasizing its commitment to supply stability and proximity to Asian customers. The expansion project is expected to be completed and fully operational by Q3 2025 [1]. Group 1: Production and Market Dynamics - The capacity enhancement of silane-functionalized liquid polybutadiene further solidifies Evonik's position as a reliable partner in the specialty chemicals sector. The company aims to meet the growing demand for this high-performance additive through localized production and increased global capacity [2]. - Liquid polybutadiene rubber is derived from non-functionalized liquid rubber (LPB) and can be modified to create different performance variants such as CTPB (carboxyl-terminated liquid polybutadiene) and HTPB (hydroxyl-terminated polybutadiene) [3]. - Europe is the most significant production region, holding a 43.74% market share in 2022, while China is expected to maintain the fastest growth rate, with a projected market share of 20.38% by 2029. Non-functionalized liquid polybutadiene is anticipated to account for 32.93% of revenue share by 2029, with tires representing approximately 51.82% of revenue share in 2022 and a CAGR of about 8.11% in the coming years [3]. Group 2: Key Manufacturers - Major global manufacturers of liquid polybutadiene include Cray Valley, Synthomer, Nippon Soda, Evonik Industries, Kuraray, Idemitsu Kosan, Tianyuan Aerospace Materials, Efremov Synthetic Rubber Enterprise, and Qilong Chemical [4].

Core Viewpoint - The article discusses the environmental impact report acceptance for the high-temperature nylon 6T resin modification project by Pingdingshan Shennma Engineering Plastics Co., Ltd, highlighting the company's efforts to upgrade its production capabilities without increasing overall production capacity [2][4]. Group 1: Company Overview - Pingdingshan Shennma Engineering Plastics Co., Ltd was established on September 6, 1995, and is a wholly-owned subsidiary of Henan Shennma Nylon Chemical Co., Ltd. The company specializes in manufacturing and processing plastics, chemical fibers, and their raw materials, as well as the research and promotion of nylon 66 resin synthesis technology [5]. Group 2: Project Details - The existing 23,000-ton intermittent polymerization unit was shut down in 2023, and the company plans to modify this unit. The modification will replace a 1,000-ton scale, while the remaining 22,000 tons will undergo separate upgrades [3]. - The modification project does not increase production capacity but aims to convert the existing 1,000-ton scale into a more advanced and economically viable product. The company intends to adopt a domestically advanced high-temperature and high-pressure solution polycondensation production process for the 1,000-ton high-temperature nylon 6T resin project, with a designed capacity of 1,000 tons per year [4].

Core Viewpoint - The article discusses the environmental impact assessment and the development of a pilot project for the production of adiponitrile by Ningxia Botai New Materials Technology Co., Ltd, highlighting the company's plans for industrialization and the challenges faced in the production process [2][3]. Group 1: Project Overview - Ningxia Botai New Materials Technology Co., Ltd is initiating a pilot project for a 100 tons/year adiponitrile production facility, which will utilize methanol and butadiene as raw materials through a specific chemical process [2][3]. - The pilot project is designed to last for one year, with an expected output of 100 tons of adiponitrile, 15 tons of 2-methylpentanedinitrile, and 50 tons of ammonium sulfate, which will be used for performance testing and further R&D [2][3]. Group 2: Future Plans - The company plans to implement a 10,000 tons/year industrial demonstration project for adiponitrile in 2023, along with securing land for a 200,000 tons/year project [2]. - The production process for the larger project involves a three-step method: preparation of formamide, decomposition to produce hydrogen cyanide, and synthesis of adiponitrile, although this project is currently on hold for optimization [2][3]. Group 3: Investment and Infrastructure - The company intends to invest 36.7 million yuan to lease facilities at the Ningdong Energy Chemical Base for the pilot project, ensuring that existing infrastructure will support storage, transportation, and wastewater treatment [3].
