Xinjiang Dushanzi Petrochemical Company, a subsidiary of China National Petroleum Corporation (CNPC), has achieved industrial mass production and large-scale supply of POE (polyolefin elastomer), known as “industrial gold,” using the vapor-phase method. Production volume is expected to reach nearly 60,000 tons in 2025, effectively reducing dependence on imported products in emerging industries such as solar power generation and new energy vehicles.

POE combines the processability of plastic with the high elasticity of rubber, making it useful in a wide range of applications, including photovoltaic modules, lightweight automotive components, and high-end packaging. POE solar cell encapsulation film is an important encapsulation material for high-performance photovoltaic modules. Due to high barriers to entry for production technology and strict process control, China has relied on POE imports for many years, resulting in high product prices. Dushanzi Petrochemical Company has adopted its own self-developed gas-phase process to fill a technological gap in related fields. The light transmittance of its main product reaches internationally advanced standards, and its quality stability is among the best among domestically produced POEs. The solar cell encapsulation film produced using this process has excellent weather resistance, water vapor barrier properties, and a long service life. Compared to the internationally mainstream solution-based process, the gas-phase process is more environmentally friendly, consuming approximately 60% of the energy required. Furthermore, since no solvents are emitted during the manufacturing process, the product has fewer volatile components and a lower odor.

Since the beginning of the 14th Five-Year Plan, China National Petroleum Corporation (CNPC) has accelerated the construction of its “refining, chemical, biological, and raw materials” industrial structure and expedited the release of new production capacity and the development of new products. It has successfully created a number of market-influential giant products, such as nitrile rubber and high-end polyolefins. New materials production has maintained a growth rate of over 50% for four consecutive years, providing crucial support for promoting the transformation and upgrading of the refining and chemical industry, enhancing the resilience of the industrial chain, and ensuring the security of key materials.

It is understood that with the completion of other POE projects by CNPC, the company’s total production capacity is expected to exceed 300,000 tons by the end of 2026, providing important guarantees for the supply chain security of emerging industries such as new energy.
