In the rigid world of automobiles dominated by steel and machinery, silicone rubber plays an indispensable role with its soft and adaptable nature. From engine compartments to cockpits, and from traditional fuel vehicles to new energy vehicles, silicone rubber is everywhere.

1. Heat-Resistant Pioneers in Engines

Automobile engines generate substantial heat during operation, posing challenges for ordinary materials to withstand long-term high temperatures. Silicone rubber, with its wide temperature adaptability from -60°C to 250°C, has become the 首选 for engine seals. For example, the intake manifold gaskets of turbocharged engines use silicone rubber, which can endure temperatures exceeding 200°C while resisting oil and coolant corrosion, ensuring efficient engine performance.

2. Gentle Protectors of Airbags

Silicone rubber coatings are a classic application in airbags. When an airbag deploys, the silicone rubber coating instantly withstands 300°C hot gas 冲击 while maintaining flexibility to prevent rupture. This material also effectively prevents gas leakage, ensuring the airbag inflates within 0.03 seconds to provide reliable passenger protection.

3. Insulating Armor for New Energy Vehicles

In electric vehicles, silicone rubber is used for battery pack insulation and sealing. Its high insulation (volume resistivity >10¹⁶ Ω·cm) and resistance to electrolyte corrosion prevent short circuits and leaks, safeguarding battery lifespan and driving safety. Tesla Model 3’s battery modules feature customized silicone rubber seals.
