Electric vehicle insulation tape: market opportunities and Yihong solutions

Market driver: EV explosion creates demand for insulation tape

The global new energy vehicle market continues to grow rapidly, with sales expected to reach 14 million vehicles in 2023, with China accounting for more than 60%. The popularity of high-voltage electrical systems (400-1000V) places strict requirements on insulation materials, which are mainly used in:

1. Battery pack insulation (GB/T 37133-2025 standard requires insulation resistance>100MΩ)

2. High-voltage wiring harness protection (needs to withstand vibration and wear)

3. Motor and electronic control system insulation (UL 1446 high temperature certification)

4. Fast charging interface protection (350kW fast charging brings instantaneous high temperature)

Market data shows that the growth rate of automotive insulation tape is higher than the industry average. It is expected that the global market size will reach US$9.09 billion in 2033, and China will occupy 56.8% of the market share in the Asia-Pacific region.
