In the field of high-end equipment such as semiconductor lithography machines and medical surgical robots, a friction deviation of 1 micron may lead to a loss of millions. The problems of volatile pollution and temperature sensitivity of traditional lubricants have long restricted the upgrade of precision manufacturing. Ethyl silicone oil is breaking this "neck-stuck" dilemma through the characteristics of nano-level film formation, zero volatility, and wide temperature range stability.

Technical analysis: The ultimate answer to micron-level friction

The core advantages of ethyl silicone oil in precision manufacturing:

1. Molecular-level penetration: Siloxane chains with a particle size of <5nm can fill 0.1μm-level micropores on the metal surface;

2. Zero material migration: Volatility at 250℃ <0.1μg/(m²·h), meeting ISO Class 1 clean room standards;

3. Friction coefficient breakthrough: 0.008-0.015 (1/10 of PTFE), and the volatility after one million frictions is <3%.

Industry breakthrough: "lubrication breakthrough" of domestic high-precision equipment

• Semiconductor manufacturing: After a Shanghai lithography machine company adopted ethyl silicone oil to lubricate the guide rail, the wafer alignment accuracy was improved to ±0.5nm, and the yield rate exceeded 99.99%;

• Medical robot: Beijing Tiantan Hospital introduced a neurosurgery arm lubricated with ethyl silicone oil, and the operating tremor amplitude was reduced from 50μm to 8μm;

• Optical instruments: Changchun Institute of Optics, Fine Mechanics and Physics used ethyl silicone oil in the focusing mechanism of the space telescope, achieving no thermal deformation displacement from -80℃ to 120℃.

Data confirmation: from laboratory to mass production line

Tests at the National Key Laboratory of Tribology of Tsinghua University showed:

• In a 10^-3 Pa vacuum environment, the wear of bearings lubricated with ethyl silicone oil is only 1/20 of that of fluorine oil;

• After being used in the lead screw system of the chip packaging machine, the MTBF (mean time between failures) of the equipment was increased from 8000 hours to 25000 hours.

International competition: China's technology "overtaking on the curve"

Previously, the high-end precision lubrication market was monopolized by Japan's Molykote and Germany's Kluber. Now, the ethyl silicone oil series products developed by the Ningbo Institute of Materials, Chinese Academy of Sciences, have passed the certification tests of giants such as ASML and Zeiss. The import substitution rate has reached 37% in 2023, and it is expected to exceed 60% in 2025.

Strategic value: the "invisible fulcrum" of the trillion-dollar industry

The Ministry of Industry and Information Technology's "High-end Equipment Lubrication Technology Roadmap" clearly lists ethyl silicone oil as a key research material for the "14th Five-Year Plan". Industry calculations show that every 1% increase in its penetration rate in the field of precision manufacturing can drive the value-added of downstream industries by more than 20 billion yuan.

Future Outlook: Lubrication Philosophy in the Quantum Age

Professor Cheng, an academician of the Chinese Academy of Sciences, pointed out: "The molecular controllable modification characteristics of ethyl silicone oil make it possible to be used in cutting-edge fields such as quantum computer cooling systems and atomic force microscope probes. This is a historical opportunity for China to go from "following" to "leading."
