Upon completion of this project, the total production capacity of the synthetic rubber plant remains unchanged. The total investment for the project is approximately 106.4268 million yuan, of which about 3.8140 million yuan is allocated to environmental protection measures. Environmental assessment agency: Guangdong Huanke Technical Consulting Co., Ltd. Main environmental impacts and strategies and measures for preventing or mitigating adverse environmental effects: (1) Exhaust gases: The exhaust gases generated in the production process are recovered and treated through the flare system in the chemical plant area ； The large and small breathing processes of the used adhesive tank, as well as the exhaust gas generated during filling, are treated using the existing synthetic exhaust gas treatment facilities to ensure compliant discharge ； The unorganized waste gases generated during production processes such as the static and dynamic sealing of the equipment are discharged after appropriate control measures are implemented. ⑵Wastewater: Production wastewater is treated using the existing wastewater treatment system in the chemical plant area and then reused; it is not discharged outside. ⑶Acoustic environment: By using low-noise equipment, arranging facilities in a proper manner, and implementing measures such as sound insulation and vibration damping, noise levels are reduced to ensure that emissions at the factory boundary meet regulatory standards. ⑷Solid waste: Used oil-containing gloves and rags, floating oil, scum, sludge, used paint cans, and used molecular sieves are all considered hazardous waste. They should be collected and stored separately, and periodically disposed of by qualified companies through external contracting ； Waste lubricating oil is comprehensively utilized through the existing waste oil and residue recovery and treatment units in the chemical plant area ； The sorted collection of household waste is handed over to the sanitation department for disposal. ⑸Groundwater: This project adopts zoned anti-seepage management, with anti-corrosion and anti-seepage measures implemented in each zone. ⑹Environmental risks: This project relies on the existing accident water tanks and three-tier prevention and control system in the chemical plant area to ensure that, in the event of an accident, the accident water does not enter the external environment. Strengthen management and strictly implement various environmental risk prevention measures and emergency response plans to prevent the occurrence of environmental risk incidents. Public participation: Public participation was facilitated through methods such as website announcements, newspaper publications, and posted notices.

High-frequency copper-clad laminates are electronic circuit substrates with ultra-low dielectric loss, used in high-frequency electronic circuits; they represent the most advanced type of electronic circuit substrate material in the field of copper-clad laminates. High-performance liquid rubber is a preferred material among the main substrates for high-frequency copper-clad laminates. High-frequency copper-clad laminates made from high-performance liquid rubber possess characteristics such as a low dielectric constant, low dielectric loss, and low water absorption; they allow for fast signal propagation without distortion during transmission. Due to high technical barriers, China is highly dependent on imports for key substrates used in high-end fields such as high-frequency copper-clad laminates, which represents one of the technical challenges that China’s petrochemical industry urgently needs to overcome. Sinopec has made liquid rubber one of the key areas for research and development as a high-end new material, striving to break free from China’s reliance on other countries in this field.

Liquid rubber generally refers to a viscous, flowable liquid at room temperature; through appropriate chemical reactions, it can form a three-dimensional network structure, thereby possessing physical and mechanical properties similar to those of ordinary vulcanized rubber. From a processing perspective, its characteristic is that it can be vulcanized using a certain vulcanization method (i.e., chain extension, cross-linking, or both), and elastic products can be manufactured by casting or pumping them into molds. Compared to solid rubber, liquid rubber generally has a lower molecular weight, ranging around 2000–1000, and is considered a prepolymer. It is a liquid that flows at room temperature and belongs to the category of cast elastomers. It is easy to shape, and its processing techniques can be mechanized, serialized, and automated, which helps to reduce labor intensity and improve the working environment.
It is reported that Sinopec has made liquid rubber one of the key areas for research and development as a high-end new material, striving to break free from China’s reliance on other countries in this field. To date, Sinopec has successfully developed 4 types and 8 high-end product grades along with the corresponding production technologies for high-performance liquid rubber, and large-scale production of these products is set to begin in the near future. These high-end new materials will be widely used in 5G high-frequency communications in areas such as mobile phones, computers, automobiles, military applications, and aerospace; in flexible printing applications where high environmental standards are required, such as those related to infants, food, and cosmetics; as well as in high-performance TPVs and green tires. They will thus meet the domestic market’s demand for high-end liquid rubber products effectively. In recent years, Sinopec has been driving the high-quality development of China’s new materials industry, and has initially established a complete industrial chain that spans from research and development and production to market sales. Shanghai Petrochemical has successfully put large-tow carbon fiber into production; Zhenhai Refining & Chemical has launched the country’s first 1,000-ton-per-year high-impact polybutylene-1 plant; Yizheng Chemical Fibers has achieved industrial production of three biodegradable plastic types: PBST, PBAT, and PBSA; Maoming Petrochemical’s synthetic oil plant and 1,000-ton-per-year POE pilot plant have been successfully commissioned. In addition, Sinopec is accelerating research and development of new materials in key areas that are vital to the country’s economic and social well-being, such as high-end cable materials and medical materials. It has already established specialized new material companies and research institutes in cities like Ningbo, Tianjin, and Anqing, covering various fields including high-performance resins, high-performance synthetic rubbers, high-performance fibers, and functional membrane materials.
