Project Core Milestones: Successful Mechanical Completion, Entering the Final Sprint Stage for Commissioning

Recently, Sinopec SVW Chemical's 50,000-ton/year special PVA (polyvinyl alcohol) resin project, a core natural gas chemical base under Sinopec, successfully completed mechanical completion. The successful completion of this key milestone marks the project's official transition from the construction phase to the final sprint stage of equipment commissioning, integrated testing, and raw material production. This provides core capacity support for the high-end iteration, intelligent upgrading, and green transformation of the domestic PVA industry, and is also a landmark achievement in the transformation and upgrading of Sinopec's fine chemicals and high-end new materials sector.

Project Strategic Positioning and Capacity Upgrade Advantages

This project is a core key project for Sichuan Weihua Chemical's transformation and upgrading strategy of "restructuring and upgrading, improving quality and efficiency." It precisely aligns with Sinopec's new materials industry development strategy, focusing on the domestic substitution of high-end specialty PVA products, and completely solving the industry pain point of relying on imports for some categories of high-end specialty PVA. Its strategic value is outstanding:

- Leap in Capacity Scale: After the project is put into operation, Sichuan Weihua Chemical's total PVA capacity will increase from 160,000 tons/year to 210,000 tons/year, firmly establishing its position as the largest producer of high-end specialty PVA in China and among the world's leading producers.

- Enhanced Industry Influence: This further consolidates the company's leading position in global natural gas-based PVA production and comprehensively strengthens the core competitiveness of Sinopec's entire natural gas chemical industry chain.

- Industrial Structure Optimization: Focusing on high-value-added sectors, driving enterprises to transform and upgrade from traditional general-purpose chemicals to high-end new materials.

Characteristics and Core Application Areas of Specialty PVA Products

Compared to traditional general-purpose PVA, the specialty PVA resin produced in this project is a high-value-added functional fine chemical new material with significant comprehensive performance advantages and strong market adaptability:

- Core Product Advantages: High purity, uniform molecular weight distribution, stable water solubility, and excellent adhesion, film-forming properties, and weather resistance, far exceeding the standards of ordinary general-purpose PVA products.

- Core Application Scenarios: Deeply compatible with strategic emerging industries such as photovoltaic new energy, biomedicine, high-end food packaging, precision electronic manufacturing, automotive interior materials, and high-precision specialty papermaking.

- Market Value: Precisely fills the domestic gap in high-end specialty PVA production capacity, contributing to the self-reliance and controllability of my country's new energy and high-end manufacturing industrial chain and supply chain, and replacing imported high-end products.

Project Construction Challenges and Achievements Throughout the project, construction strictly adhered to Sinopec's high-standard engineering construction management system.

Sichuan Vinylon Works, in collaboration with all participating units, overcame numerous challenges and efficiently completed the construction tasks, demonstrating the robust engineering construction capabilities of a central state-owned enterprise:

- Construction Period: The entire project lasted 17 months, achieving the key mechanical completion milestone on schedule.

- Challenges Overcame: Successfully resolved multiple challenges, including a compact plant layout, dense overlapping operations, complex geological conditions, tight schedule, and construction under high summer temperatures.

- Management Standards: Strictly implemented the four core management requirements of safety, quality, schedule, and environmental protection, optimizing construction processes, coordinating resource allocation, and strengthening quality traceability and supervision throughout the process.

- Construction Achievements: Set a benchmark for construction speed among similar high-end fine chemical projects, fully demonstrating SVW's (Sichuan Vinylon Works) mature project management and construction capabilities. VI. Enterprise Industrial Foundation and Core Technological Advantages

Sichuan Chemical Industry Co., Ltd., as Sinopec's only core natural gas chemical base, has been deeply involved in the PVA new materials field for over fifty years, possessing profound industry experience and leading technological barriers:

- Core Technological Barriers: Possessing globally leading and domestically unique independent core intellectual property rights for natural gas-to-acetylene production, it is a benchmark enterprise in the natural gas-based PVA production field.

- Industry Standard Position: Leading drafter of national standards for the PVA industry in China, and dominant in the formulation of industry product standards and production specifications.

- Market Coverage: All product lines are of stable quality and are exported to over 60 countries and regions worldwide, possessing a mature global supply system.

- Core Upgrade Logic: This capacity expansion is a structural quality improvement and upgrade, eliminating low-end and inefficient capacity and focusing on high-end, high-value-added products, implementing the requirements for high-quality development of the petrochemical industry.

Key Highlights of the Project's Green, Low-Carbon, and Intelligent Features

The project deeply integrates petrochemical intelligent manufacturing with green and environmentally friendly processes, balancing production efficiency, product quality, and low-carbon environmental protection. It serves as a model project for industry transformation and upgrading:

- Intelligent Production System: Equipped with intelligent control systems, automated packaging systems, and online quality monitoring systems, it achieves digital management and precise quality control throughout the entire production process, meeting the standards for intelligent factory construction of Sinopec.

- Green and Energy-Saving Processes: Equipped with high-efficiency solvent recovery, comprehensive VOCs treatment, and energy-saving and consumption-reducing devices, the solvent recovery rate can reach over 95%, significantly improving resource utilization.

- Ultra-Low Emission Advantages: Emissions of waste gas, wastewater, and solid waste are all superior to national industry standards. Relying on clean natural gas as a raw material, compared with the traditional calcium carbide-based PVA process, carbon emission intensity is significantly reduced, demonstrating outstanding low-carbon advantages.

Subsequent Planning and Long-Term Industry Value

The project's mechanical construction has been successfully completed, and the subsequent production and implementation schedule is clear, demonstrating significant industrial empowerment value:

- Subsequent Work Plan: Steadily advance single-unit commissioning, integrated debugging, safety and compliance verification, and trial production, striving to achieve the goals of early production, early capacity utilization, and early profitability.

- Corporate Value: Further optimize Sichuan Chemical's product structure and enhance the market competitiveness of Sinopec's high-end fine chemicals and new energy and new materials sectors.

- Industry Value: Drive the domestic PVA industry away from low-end homogeneous competition and accelerate its transformation towards high-end, refined, functional, and green products.

- National Strategic Value: Provide a model for the transformation and upgrading of traditional petrochemical industries, contribute to the implementation of the national "dual-carbon" strategy, and solidify the independent controllability of the new materials industry chain.
