Breakthroughs in silicone oil technology have driven innovations in multiple fields

1.A major breakthrough has been made in the production process of environmentally friendly silicone oil
In 2025, the global silicone oil industry will reach a milestone in green transformation, and the new bio-based silicone oil preparation technology will pass industrial verification. This technology uses plant-based raw materials to replace traditional petrochemic-based monomers and combines enzyme catalytic processes to reduce production energy consumption by 42%, while achieving near-zero VOC (volatile organic compounds) emissions. According to industry reports, the global market size of bio-based silicone oil is expected to reach 4.597 billion yuan in 2025, an increase of 19.7% compared to last year. Among them, the Asia-Pacific region contributes 62% of the new capacity.
In the field of circular economy, a disruptive recycling technology has increased the conversion efficiency of waste silicone oil by a million times. Through the synergistic effect of gallium catalysts and boron trichloride, waste silicone oil can be decomposed into high-purity chlorosilane monomers at a low temperature of 40℃ and reused in the production of high-end electronic packaging materials. This breakthrough has reduced the life cycle carbon footprint of silicone oil by 52%, providing a compliant solution for the EU's Carbon Border Adjustment Mechanism (CBAM).

2. The application of silicone oil in the medical field has achieved a precise upgrade
The silicone oil filling technology in ophthalmic surgery has been innovated. The new low-cyclic vinyl silicone oil has successfully solved the complications caused by long-term retention. This product is processed through multi-stage evaporation and short-path distillation to keep the volatile matter content below 0.1%, and it can withstand extreme temperatures ranging from -50 ℃ to 300℃. Clinical data shows that the retinal reattachment rate using this material has increased to 92%, and the incidence of cataracts has decreased by 65%.
In the field of drug carriers, silicone oil microcapsule technology enables targeted delivery of chemotherapy drugs. Through the nanoscale emulsification process, the drug encapsulation rate reached 91%, and in animal experiments, the tumor suppression rate was 37% higher than that of traditional therapies. This technology has entered the Phase II clinical trial stage and is expected to be industrialized in 2027.


3. The demand in the fields of new energy and electronics has exploded
With the increasing penetration rate of new energy vehicles, the market for thermal silicone oil used in power batteries has witnessed explosive growth. The global production of new energy vehicles is expected to exceed 25 million units in 2025, driving a 43% increase in the demand for high thermal conductivity silicone oil. The thermal conductivity of the product will rise from 1.2W/m · K to 3.8W/m · K. In the photovoltaic field, silicone oil-based encapsulation materials have enhanced the PID (Potential Induced Decay) resistance of modules by 60%, extending their outdoor service life to over 30 years.
The miniaturization trend of 5G communication equipment is promoting the application of silicone oil in high-frequency electronic components. The dielectric loss factor of the new fluorosilicone oil is as low as 0.0002, and the signal transmission attenuation in 6G millimeter-wave devices is reduced by 28% compared with traditional materials. Leading domestic enterprises have built a high-frequency silicone oil production line with an annual output of 5,000 tons, and the domestic production rate has increased from 35% to 68%.


4. Policies drive the industry to transform towards high-end
China's "14th Five-Year Plan for the New Materials Industry" has listed medical-grade silicone oil, bio-based silicone oil, etc. as key development directions, and will provide subsidies of up to 3 million yuan per ton for projects that meet the standards. The EU's Sustainable Chemicals Strategy requires that the proportion of bio-based components in cosmetic silicone oil should not be less than 30% after 2027, directly driving a 25% increase in the demand for modified silicone oil.
The upgrade of the testing and certification system has further regulated the market. The International Organic Textile Association has tightened the threshold for silicone oil residues from 1ppm to 0.3ppm, driving an 82% increase in the demand for gas chromatography-mass spectrometry (GC-MS) equipment. Through intelligent transformation, domestic enterprises have raised the batch stability of their products to 99.8%, and the rate of superior products has increased from 78% to 94%.
