1. Current status: technology-driven and market expansion in parallel
As a high-performance composite material, silicone mica tape uses silicone resin as the matrix and mica as the filling material. It combines the flexibility of silicone with the heat resistance of mica and is widely used in insulation sealing under high temperature and high pressure environments. The global market size is expected to exceed 6.23 billion yuan in 2025, with an annual compound growth rate of 16.8%, of which the Asia-Pacific region accounts for more than 58%. As the world's largest producer and consumer, China's market size is expected to exceed 3.6 billion yuan.

Technological breakthroughs and product iterations:
Improved high temperature resistance: Domestic companies have achieved mass production of 0.08mm ultra-thin mica tapes, and the temperature resistance level has been increased to above 1000℃, meeting the needs of extreme environments such as aerospace and nuclear power.

Environmental protection transformation: The R&D investment in environmentally friendly silicone resins continues to increase, and VOC emissions have been reduced by 80%, meeting the EU REACH certification requirements.
Functional expansion: Nano-modification technology increases the thermal conductivity of the product to 0.45W/(m·K), 50% higher than traditional products; the flame retardant grade reaches the UL94V0 standard, and the smoke density index is less than 50.
Diversification of application fields:

New energy field: The application of wind power insulation materials accounts for 32%, the growth rate of demand for photovoltaic module packaging materials remains above 25%, and the market size of electric vehicle battery pack insulation solutions exceeds 800 million yuan.
Traditional field: The penetration rate in the field of power equipment continues to increase, and the localization rate of mica tape for high-speed rail motors has reached more than 85%.

2. Outlook: Emerging demand and green transformation dual-wheel drive
