Against the background of the upgrading of high-end manufacturing towards precision and intelligence, vacuum diffusion pump oil, as the "blood" of the vacuum system, its market pattern is constantly restructured with the iteration of downstream demand, and the industrial development presents distinct characteristics of accelerated technological iteration, optimized demand structure and diversified competition pattern. At present, the global vacuum diffusion pump oil market is getting rid of traditional homogeneous competition, transforming towards high-end, customized and greenization. Domestic enterprises, relying on cost advantages and technological breakthroughs, are gradually breaking the foreign monopoly and promoting the industry into a new stage of high-quality development.
From the perspective of market competition pattern, the global market has formed a hierarchical pattern of "high-end monopoly, mid-end competition and low-end long tail". In the high-end market, international giants such as Dow, Shin-Etsu and Merck monopolize the market of special products such as ultra-high vacuum and radiation resistance with core technological barriers. Their products are widely used in high-end scenarios such as advanced semiconductor manufacturing processes and aerospace engine testing. With stable performance and perfect services, they account for more than 70% of the global high-end market, with a product premium rate of more than 50%. The mid-end market is highly competitive, with domestic enterprises competing with small and medium-sized foreign enterprises. Domestic enterprises break through with advantages of high cost performance and rapid response. In 2024, the market share of local enterprises in the mid-end market has reached 45%, gradually replacing imported products and applying to scenarios such as photovoltaic coating and ordinary electronic manufacturing. The low-end market is dominated by small enterprises, with low technical threshold and serious homogenization, mainly meeting the basic needs of low-end vacuum equipment, and the market share is gradually shrinking.
In terms of demand structure, differentiated demand in downstream fields promotes market segmentation. The semiconductor field accounts for the highest demand, reaching 42%. Among them, the demand for ultra-high vacuum diffusion pump oil in 12-inch wafer production lines and advanced packaging scenarios is surging, driving the growth of the high-end product market; the aerospace and scientific research fields account for 18% of the demand, which has strict requirements on the high and low temperature resistance and radiation resistance of oil products, and the demand for special products continues to rise; the photovoltaic, metallurgy, vacuum coating and other fields account for 40% of the demand, mainly mid-end products, and the demand keeps steady growth with the expansion of photovoltaic module production capacity. In addition, emerging fields such as quantum computing and controlled nuclear fusion are promoting the R & D of ultra-clean and impurity-free vacuum diffusion pump oil, becoming a new growth hotspot of the market.
The industrial development trend focuses on three core paths. First, technological innovation drives product upgrading. Enterprises focus on R & D of low vapor pressure, long service life and high purity products, break through core technologies such as molecular structure optimization and high-purity raw material purification, and narrow the gap with international giants; second, domestic substitution continues to deepen. Domestic enterprises increase R & D investment, promote products to pass international certification, expand high-end supply chains, and it is expected that the global market share of local enterprises will exceed 20% in 2028; third, green and collaborative development. The solvent-free production process is gradually popularized, the oil recycling mode is implemented, and enterprises cooperate deeply with vacuum equipment manufacturers to build an integrated service system of "consumables-equipment-operation and maintenance". In the future, with the continuous release of demand in downstream high-end fields, the vacuum diffusion pump oil market will continue to expand, the competition pattern will be further optimized, and domestic enterprises are expected to achieve a leap from "following" to "leading".
