Material Properties

Structure of Silicone Foam

Silicone foam is special because of how it is built inside. Engineers make it with lots of tiny cells that connect together. This design lets air move through the foam easily. It also helps the foam stay strong, even after being used for a long time. The foam's cell pattern lets it take in and spread out force from bumps. This makes it very good at stopping shocks.

• The foam does not change shape much when pressed. It does not shrink or bend easily.
• It bounces back and cushions parts that need protection.
• There are open-cell and closed-cell types. Closed-cell silicone foam keeps water out and stays bendy in hot or cold places.
• The siloxane backbone keeps the foam tough and long-lasting, even when things get rough.
• The foam's structure helps it soak up shakes and hits. This makes it great for stopping vibrations and shocks.
• Note: Silicone foaming materials keep working well from -60°C to 230°C. They do not get damaged by sunlight, chemicals, or bad weather. This means they last a long time in electric cars.

Key Features for New Energy Vehicles

Silicone foam has many traits that make it good for new energy cars. The table below shows these traits and why they help:

Silicone foam is light, blocks heat, and stops fires. These things help keep batteries safe, control heat, and make electric cars work well and safely.

Application of Silicone Foam in New Energy Vehicles

Battery Protection

Shockproof silicone foam is very important for battery safety in new energy vehicles. Engineers use it to make fire protection sheets between battery cells and modules. These sheets stop heat from spreading and help prevent thermal runaway. The foam keeps its shape even when it gets hot. It gives strong dielectric protection for high-voltage parts.

Silicone foam pads help with battery cell changes during charging and discharging. This is needed for energy density lithium battery packs, where cells can swell or shrink. The foam takes in these changes and stops damage. Fire-resistant potting foams fill spaces between cells. This helps machines build batteries and makes sure everything fits tight.

Manufacturers use silicone foam because it seals out water. This keeps moisture, dirt, and salt away from the battery pack. If these get in, they could cause short circuits. The foam meets strict safety rules like UL 94 V0 for stopping fires and IP67 for water resistance. These features make it a top choice for battery protection in cars.

Note: Shockproof silicone foam gives good shock absorption and impact protection. It cushions battery modules from bumps and shakes. This lowers the chance of damage in accidents or rough driving.

Gap Filling and Sealing

Silicone foam is used as a gap filler and sealant in new energy vehicle batteries. The foam fills spaces between battery cells and holds them in place. This adds strength to the battery pack and stops movement that could cause problems.

Silicone sealing foam makes a tight seal around battery modules and electronics. Its elastic cell structure lets it compress by 30-60%. It can fit many shapes and sizes. The foam stays flexible and works well even after opening and closing the battery case many times.

Manufacturers use machines to put the foam in the right spot every time. The foam sticks well to steel, aluminum, and plastics. This makes it good for many car designs. Its low water absorption and strong sticking power keep water, dust, and bad weather away from electronics.

Key benefits of gap filling and sealing with silicone foam:

• Stops thermal runaway by giving thermal insulation.
• Adds protection against shocks and vibrations.
• Keeps the seal tight after many uses.
• Helps fast and easy production with machines.

Vibration Damping

Vibration damping is another big use for silicone foam in cars. Sensitive parts like battery management systems and electronics need to be safe from shaking and noise. Silicone foam pads, like BISCO BF-1000, give good compression set resistance and stress relief in hot or cold.

These damping materials block noise and vibration from the car moving. Compression pads hold battery cells tight but let them expand and shrink. This keeps shock absorption working well. The foam's open cell structure lets it bounce back fast and not stay squished. This means it can take many shocks over the car's life.

Silicone foam keeps electronics safe from water, rust, and chemicals. It stays strong even with sudden temperature changes and repeated stress. This is important for long-lasting batteries and electronics. The foam's toughness and resistance to sunlight and wear help batteries and electronics last longer.

Main advantages of using shock-absorbing cushions in vibration damping:

• Gives cushioning and shock absorption for battery modules and BMS.
• Works well in very hot or cold, from -65°F to +400°F.
• Lowers stress on parts and helps make cars lighter.
• Keeps electronics safe and working for a long time.
• Tip: Using silicone foam as a shock absorber helps lower weight, keep heat in, and make new energy vehicles safer. Its shock absorption makes it a top pick for engineers who want reliable and long-lasting solutions.
