1. Market potential: demand-driven and industrial upgrading
With the continuous growth of global car ownership, the global automotive aftermarket is expected to exceed US$1.5 trillion in 2025, of which the average annual growth rate of the car care segment is 8%. With its weather resistance, hydrophobicity and environmental protection characteristics, silicone materials have become the core materials for upgrading car care products. In scenarios such as car paint crystal plating, interior maintenance, and tire care, the penetration rate of silicone products has exceeded 40%, and it is growing at a rate of 15% per year. The popularity of new energy vehicles has further driven demand, and the demand for silicone materials in battery pack protection, headlight sealing and other links has increased by 30% compared with traditional fuel vehicles.

2. Technology trend: integration of high-end and intelligent
Long-term protection technology: Nano silicone plating agent uses self-repairing coating technology to extend the paint protection period to 24 months, and also has anti-ultraviolet and anti-scratch functions.
Environmentally friendly formula upgrade: Bio-based silicone care agents use renewable resources such as corn starch as raw materials, VOCs emissions are reduced by 90%, in line with EU REACH regulations, and the market share is expected to exceed 25% in 2025.
Intelligent care system: The silicone formula design platform driven by AI algorithms can automatically generate customized care plans according to the vehicle use environment (such as high temperature and humidity, salt spray corrosion) to improve product adaptability.

3. Application scenario expansion: from surface to core components
Battery thermal management: Silicone thermal conductive potting glue is used to fill the gap between battery packs, and the thermal conductivity is increased to 3W/m·K, ensuring efficient heat dissipation of the battery pack in a wide temperature range of -40℃ to 150℃.
Intelligent headlight sealing: Liquid silicone rubber light guide technology increases the optical efficiency of headlights by 40%, while meeting the IP69K waterproof level requirements.
Lightweight interior: Silicone leather replaces traditional leather, reduces weight by 30%, and has flame retardant and antibacterial properties. It has been used in Tesla Model Y and other models.

In the next five years, silicone in the field of automotive care will evolve towards "long-lasting, environmentally friendly, and intelligent". The resonance effect of technological breakthroughs and demand upgrades will drive the market size to exceed 10 billion yuan and become an important growth pole in the automotive aftermarket.
