Silicone foam materials have been widely used in the industry. Silicone foam can generate stable rebound stress within a certain compression range, so it is especially suitable for ensuring the safety and reliability of electric vehicles during their service life. The compression curve of the silicone foam shows the material's advantage in withstanding long-term compression and temperature. This is critical to ensure stable performance over the life of the battery. At the same time, silicone foam also extends the life of electric vehicle batteries by shock absorption and protection of sensitive components.
- Wide operating temperature – silicone foam has a temperature range of -67°F to 392°F (-55°C to 200°C).
- Water sealing – closed cell products offer good water sealing with relatively low compressive forces.
- Dust sealing – open cell and closed-cell products can be used for sealing out dust with low compressive forces.
- Compression set resistance – silicone foam offers excellent compression set resistance (ability to rebound to original
- thickness).
- UV and ozone resistance – silicone products have excellent UV and ozone resistance due in part to their inorganic backbone. This provides long-term performance.
- UL gasket – most silicone foam products are UL 94 flame rated for the gasket.
