1. Market size and growth drivers
The market size of China's mechanical seals is expected to exceed 38 billion yuan by 2025, with an average annual compound growth rate of over 7.5%. The proportion of high-end products (such as dry gas seals and magnetic fluid seals) will increase to 45%. The growth mainly comes from three aspects:
Policy driven: The localization rate target for national strategic industries such as nuclear power and hydrogen energy has been raised to 85%;
Technological iteration: The application of silicon carbide and graphene composite materials extends product life by more than three times;
Emerging demand: The semiconductor equipment sealing market is growing at a rate of 15%, with the photovoltaic industry accounting for over 30% of magnetic mechanical seals applications.
