On July 10, it was reported that Daqing Refining & Chemical Company produced nearly 17,000 tons of food-grade white oil in the first half of the year—a year-on-year increase of 12.78% and a record high for the period. Meanwhile, the company’s independently developed No. 4 specialty white oil successfully penetrated the high-end market for lithium-ion battery separators, achieving volume-based import substitution and delivering impressive results across the dual sectors of public health/consumer goods and new energy.
As one of the first domestic enterprises to establish specialized production of food-grade white oil, Daqing Refining & Chemical currently produces three mainstream grades—No. 1, No. 2, and No. 4—at scale. Notably, the No. 4 grade has obtained NSF H1 certification from the United States. Thanks to its characteristics—colorless, odorless, and highly stable—the product has expanded into consumer sectors such as baking mold release agents, fruit and vegetable preservation, pharmaceutical excipients, and skincare products for mothers and infants.
While consolidating its position in the consumer market, Daqing Refining & Chemical has aligned itself with national "dual carbon" goals and the rapid growth of the new energy industry, extending the quality advantages of its food-grade white oil into the high-end materials sector. "Our independently developed No. 4 specialty white oil meets all core technical specifications—such as viscosity and flash point—required for lithium-ion battery separator production. It is now being supplied in bulk to leading domestic lithium-battery enterprises, successfully breaking through international technical barriers," said Zou Li, supervisor of the production technology group at the No. 3 Refining Department. The successful domestic substitution of this critical material has not only effectively reduced the domestic lithium-battery industry's reliance on imported specialty oils but has also provided robust support for the security and self-reliance of my country's new energy supply chain.
