Polysiloxane materials lead the technological innovation in new energy and environmental protection

1.Breakthrough in the field of new energy batteries: Polysiloxane enhances battery performance
New polysiloxane-based solid electrolyte materials have shown breakthrough progress in lithium-ion batteries. Studies have shown that the high dielectric constant polysiloxane electrolyte membrane prepared by photo-curing technology can achieve an ionic conductivity of 2.6×10⁻⁵ S/cm at room temperature and a lithium transfer number of 0.72, which is significantly better than that of traditional liquid electrolytes. This material not only resolves the safety hazard of flammable and explosive liquid electrolytes, but also increases the storage modulus by three orders of magnitude through a semi-interpenetrating network structure design, achieving a capacity retention rate of over 80% after 50 cycles. In the field of power batteries, the compound annual growth rate of demand for polysiloxane-based thermal conductive structural adhesives exceeds 40%. Their application in the electronic control systems of new energy vehicles can effectively reduce the risk of battery thermal runaway.

2. Material substitution driven by environmental protection regulations: Application of polysiloxane in Coatings
With the implementation of the "Action Plan for the Governance of New Pollutants", traditional fluorine-containing water and oil repellents are being replaced at an accelerated pace. Reactive polysiloxane, with its fluorine-free property and excellent hydrophobic and oleophobic performance, has become the preferred solution in the pulp molding industry. The three-dimensional hydrophobic layer formed by its active ingredients after drying can increase the water resistance grade of packaging materials to IPX7, while meeting the strict requirements of the EU REACH regulation for volatile organic compounds (VOCs). In the construction field, polysiloxane-modified coatings have occupied 35% of the market for curtain wall sealants in super high-rise buildings, and their weather resistance is more than three times higher than that of traditional acrylic coatings.

3. Biodegradable polysiloxane: A sustainable solution for the medical field
Substantial progress has been made in the field of medical implants using biocompatible polysiloxane materials. The polysiloxane glod-type sensor modified by carbon nanotube composite can achieve non-invasive detection of uric acid concentration in sweat and saliva, with a detection error of less than 10%. Its reliability has been verified in dietary intervention experiments. Meanwhile, degradable polysiloxane scaffold materials have entered the animal experiment stage. Their degradation cycle in vivo can be precisely regulated by the content of side-chain ester groups, providing a new option for the treatment of cardiovascular diseases. The biocompatibility of this type of material has been certified by ISO 10993, and its cytotoxicity rating is grade 0.

4.Industry experts predict that the polysiloxane market will witness rapid growth
Market data shows that the market size of polysiloxane in China is expected to reach 46.8 billion yuan in 2025 and exceed 78 billion yuan in 2030, with an average annual compound growth rate of 10.5%. The market share of high value-added products such as liquid silicone rubber (LSR) and hydrogen-containing silicone oil will increase from 34% to 52%, becoming the main growth driver. In terms of exports, the export value of polysiloxane reached 5.8 billion US dollars in 2025, with the Southeast Asian and European markets accounting for over 60%. Among them, photovoltaic encapsulation adhesives and electronic-grade silicone oil have become the main export categories. With the advancement of the "Belt and Road Initiative", the overseas production capacity layout is accelerating. It is expected that the export volume will double to 11 billion US dollars by 2030.
