Vinyl silicone oil technological innovation drives breakthroughs in multiple fields. 3D printing and nanomaterials have become new growth poles

1. Achieve dual breakthroughs in materials and processes in the 3D printing field
In the fields of flexible electronics and smart wearable devices, the combination of vinyl silicone oil and liquid metal has opened up a new path for sensor manufacturing. Liquid metal silicone (LMS) ink with self-encapsulation function was successfully developed by adding terminal vinyl silicone oil and platinum catalyst to liquid metal. During the embedded 3D printing process of this ink, the catalyst diffusion effect can cure the surrounding silicone, directly constructing a composite material with excellent electrical conductivity. Experimental data show that the sensitivity of the flexible tactile sensor based on this technology reaches 0.308V/kPa⁻¹, the linearity exceeds 0.99, and it still maintains stable performance after more than 10,000 cycles of durability tests. In addition, this technology also realizes the integrated integration of sensors and actuators, providing a brand-new solution for the manufacturing of complex structures such as soft robot grippers.

2. The performance of nanocomposites has been significantly improved
The application of vinyl silicone oil in the field of nanomaterials has been further expanded. In the preparation of PTFE (polytetrafluoroethylene) nanocomposite membranes, vinyl silicone oil as an impregnating agent can significantly improve the processing performance of PTFE resin. Through the hot calendering process, part of the vinyl silicone oil is extruded to form micron-sized pores, while the remaining silicone oil polymerizes and solidifies at high temperatures, resulting in a nanometer-sized concave-convex structure on the surface of the composite film. This structure not only enhances the hydrophobicity and anti-freezing performance of the material, but also increases the tensile strength to over 8MPa while maintaining good flexibility. In the anti-icing coating of wind turbine blades, the application of this composite film reduces the adhesion of the ice layer by 60%, effectively extending the service life of the equipment.

3. International market demand continues to rise
With the deep integration of the global industrial chain, the export of vinyl silicone oil has shown a high growth trend. In the first ten months of 2024, the export volume of a certain domestic enterprise increased by 119% year-on-year, and its products covered more than ten countries and regions including the United States, Russia and South Korea. In the high-end electronic packaging field, the low ion content (metal ions <20ppm) and high light transmittance (>95%) of electronic-grade vinyl silicone oil have become the core advantages in international competition, driving the share of domestic products in the 5G communication base station and semiconductor packaging markets to steadily increase. In addition, the research and development progress of bio-based vinyl silicone oil has also attracted international attention. Its characteristic of having a biodegradation rate of over 50% is expected to achieve large-scale production by 2026, providing a Chinese solution for global sustainable development.

4. Environmental protection regulations are forcing industrial upgrading
The further tightening of environmental protection policies in 2025 will prompt the industry to accelerate its green transformation. A certain enterprise was fined 36,400 yuan for building a thermal conductive flexible sheet project without approval, highlighting the importance of environmental impact assessment compliance. Meanwhile, leading enterprises in the industry have introduced continuous production processes through technological innovation, adopting ultrasonic vibration reactors and high-speed atomization devolatilization systems. This has increased the conversion rate of vinyl silicone oil to 98.5% and reduced energy consumption by 40%. The application of green formula technology is also expected to enable the market share of environmentally friendly products to exceed 60% by 2025, significantly reducing the emissions of volatile organic compounds (VOCs). Driven by both policy guidance and market demand, the vinyl silicone oil industry is rapidly evolving towards low energy consumption and low pollution.

5. Electronic packaging technology is moving towards refinement
In the field of semiconductor packaging, the low ring content (D3-D6<50ppm) and high purity characteristics of vinyl silicone oil have become key indicators. By improving the catalytic equilibrium method and centrifugal extraction process, the volatile matter of electronic-grade silicone oil can be controlled within 0.1wt%, meeting the usage requirements in aerospace-grade high vacuum environments. A certain enterprise has adopted a fully automated production line. Through the combined dehydration process of screw extrusion and thin-film evaporation, it has achieved large-scale production of products with different viscosities (100-80,000mPa · s). The daily output of a single line reaches 15 tons, and its performance is on par with imported high-end products. This technological breakthrough not only enhances the reliability of chip packaging but also provides material support for the miniaturization of flexible displays and wearable devices.
