With the acceleration of the global industrial modernization process, the demand for vacuum environments in high-end manufacturing, scientific research experiments, new energy and other fields continues to upgrade. As the core supporting consumable of the vacuum system, the market pattern and industrial development trend of vacuum diffusion pump oil are closely aligned with the iteration direction of downstream industries, showing distinct characteristics of policy guidance, technology-driven and competition upgrading. At present, the industry is in a critical cycle of accelerated synthetic oil substitution, deepened domestic substitution and accelerated green transformation. While the market scale is steadily expanding, the competition pattern is also continuously optimized, highlighting the high-quality development trend of the industry.
The market pattern presents the core characteristics of "echelon stratification and differentiated competition between Chinese and foreign enterprises", forming three clear competitive echelons. The first echelon is international leading enterprises, with giants such as ExxonMobil, Dow, Shin-Etsu and DuPont as the core. Relying on core formula technology, mature global supply chains and brand advantages, they monopolize the global high-end synthetic vacuum diffusion pump oil market. Their high-end products such as perfluoropolyether (PFPE) are suitable for advanced semiconductor manufacturing processes and extreme aerospace working conditions, accounting for more than 70% of the global high-end market, with significant product premium, and form deep binding cooperation with leading vacuum equipment enterprises. The second echelon is domestic leading enterprises, represented by Sinopec, Shanghai Kangpeng and enterprises related to Mengcheng Fanfeng Vacuum. Through independent R & D and technology introduction, they have achieved breakthroughs in localization of mid-to-high-end synthetic oils. Sinopec has optimized the performance of mineral oil-based products with invention patents, and relying on local cost advantages and rapid response capabilities, it dominates the domestic mid-end market. In 2024, the market share of local enterprises in the mid-end market has reached more than 45%. The third echelon is small and medium-sized enterprises, mainly focusing on mid-to-low-end mineral oil products, with low technical thresholds and serious homogenization, mainly serving regional low-end manufacturing scenarios. Affected by synthetic oil substitution and environmental policies, their market share continues to shrink.
The market demand side shows a trend of "surge in high-end demand and expansion of segmentation". In terms of overall scale, the global vacuum pump lubricating oil market sales reached 1.102 billion US dollars in 2023, and vacuum diffusion pump oil, as the core category, accounted for more than 50%. It is expected to grow steadily at a compound annual growth rate of 2.62% along with the industry from 2024 to 2030. In terms of demand structure, the semiconductor field is still the core growth pole, accounting for 42%. The expansion of 12-inch wafer production lines has driven a surge in demand for ultra-high vacuum and ultra-clean products; the new energy field is developing rapidly, and scenarios such as lithium battery cell manufacturing and cadmium telluride thin-film solar energy production have driven the demand for special oil products suitable for harsh vacuum environments; the food and pharmaceutical fields have stable demand, mainly focusing on mid-end synthetic oils and optimized mineral oils, accounting for more than 23% of the total demand; the scientific research field focuses on ultra-clean and radiation-resistant special products, becoming an important application scenario for high-end products.
Driven by policies, technology and market, the industrial development trend focuses on three directions. First, green and compliant transformation. The tightening of environmental policies promotes the popularization of solvent-free production processes, and the waste oil recycling model is gradually implemented. At the same time, the ban on mercury vacuum pumps at the end of 2025 indirectly promotes the substitution of environmentally friendly vacuum diffusion pump oil; second, technological upgrading and product high-endization. With its excellent performance, synthetic oil is expected to account for 79.08% of the vacuum pump lubricating oil market revenue by 2030, and enterprises focus on breaking through core technologies such as high-purity raw material purification and molecular structure optimization; third, deepened domestic substitution and collaborative development. Domestic enterprises increase R & D investment, promote products to pass international certification, and at the same time carry out joint R & D with vacuum equipment enterprises to build an integrated system of "consumables-equipment-operation and maintenance". It is expected that the global market share of local enterprises will exceed 20% in 2028, gradually achieving a leap from "following" to "leading".
