What are the fire and sound insulation materials for new energy vehicles?

The use of fire-proof and sound-proof materials for new energy vehicles shall comply with the following conditions:

1.a is nonflammable, which can effectively avoid fire.

2. Inorganic environmental protection. Choosing environmental protection materials can greatly reduce indoor air pollution inside the car.

3. The weighted sound insulation is ≥30DB, and the noise outside the car is relatively large when the car is driving.

4.CAS nano-Al-Mg fireproof damping soundproof felt is an environmentally friendly nano-material that can prevent fire and sound simultaneously.
