Silicone products, how will silicone buttons define the future driving experience?
From Tesla to BYD, revealing how silicone products have become the "hidden champion" of new energy vehicles
New energy vehicle market in 2025: the golden age of silicone keypads
In 2025, the global new energy vehicle market will usher in a historic turning point: China's new energy vehicle sales are expected to exceed 16.5 million, accounting for more than 60% of the global market. Against this background, silicone keypad and silicone products ,
as core components, are quietly reshaping the supply chain of the automotive industry. Brands such as Tesla and BYD have not only promoted the intelligent upgrade of new energy vehicles, but also pushed the application of silicone materials to a new level.
1.Weather-resistant silicone keypad: the "smart touch" revolution of new energy vehicles
As the penetration rate of L2+ autonomous driving exceeds 65%, the complexity of in-car interactive interfaces has increased dramatically. Silicone keypads have become the industry benchmark with their three core advantages：
1.Extreme environment adaptability : Stable operation at -40℃ to 200℃, perfect for the high temperature and high humidity markets such as Latin America and the Middle East where new energy vehicles will be exported in 2025;
2. Upgrade of human-computer interaction : With the popularization of AI voice assistants, physical buttons need to work seamlessly with touch screens, and the unique damping feeling of silicone material improves the accuracy of blind operation;
3. Upgraded safety protection : Fully enclosed silicone soft patch design, waterproof level up to IP68, eliminating the risk of water seepage and short circuit in heavy rain.
Industry case : Tesla Cybertruck's door control module uses a multi-layer silicone keypad structure and has passed NASA-level weather resistance tests, making it the preferred configuration for desert and polar explorers.
2. Four major battlefields of silicone products: from battery revolution to lightweight
The "four trends" of new energy vehicles in 2025 (electrification, intelligence, networking, and lightweight) have opened up diversified application scenarios for silicone products
Battlefield 1: Solid-state battery thermal management
Semi-solid-state battery mass production exceeds 10GWh, and silicone thermal pads become the core components of battery packs
1. The thermal conductivity is 8W/m·K, which is 300% higher than that of traditional materials;
2. The elastic buffer structure adapts to the expansion of the battery cell and extends the life by 30%.
The battery pack of new energy vehicles will generate a lot of heat during operation. If the heat is not dissipated in time, it will lead to performance degradation or even damage. Silicone heat dissipation pads are ideal materials for battery pack heat dissipation due to their good thermal conductivity and insulation. They can effectively isolate external pollutants such as moisture and dust, while quickly conducting the heat generated by the battery pack to ensure its normal operation.
1. BYD's Hungarian factory production lines all use ozone-resistant silicone seals to cope with the extremely cold climate in Eastern Europe;
2. Compatible with high-frequency vibration conditions of 5G-V2X equipment, with a sealing life of over 100,000 hours.
Silicone seals are ideal sealing materials for key parts of new energy vehicle engines, gearboxes, battery packs, etc. due to their excellent heat resistance, sealing and weather resistance. These seals can effectively prevent the leakage of lubricating oil, coolant and battery fluid, ensuring the normal operation of the vehicle.
Battlefield 3:
With the goal of reducing the weight of the vehicle body by 20% by replacing lightweight materials, silicone shock absorbers have become the new favorite of the suspension system
1. The energy absorption rate is increased by 40%, matching the rapid acceleration condition of the 800V high-voltage platform;
2. Integrated silicone-carbon fiber composite material achieves a breakthrough in both strength and lightness.
Due to its good flexibility and elasticity, silicone has become an ideal material for shock absorption and noise reduction in new energy vehicles. Silicone shock absorbers are widely used in the suspension system, engine brackets and other parts of automobiles. By absorbing and dispersing vibration energy, they effectively reduce the damage to automobile parts caused by vibration and impact. At the same time, silicone noise-reducing materials are also used in the exhaust system, doors and other parts of automobiles. By absorbing and reflecting sound waves, the noise level is reduced, and the quietness and comfort of the vehicle are improved.
Battlefield 4: AI intelligent driving sensors protect
the large-scale commercial use of L4 autonomous driving, and silicone coating technology protects LiDAR:
- Light transmittance>92%, dust and abrasion resistance is better than glass material;
- Flexible rubber-coated buffer structure reduces collision repair costs by 60% .
The silicone encapsulation process can effectively isolate external pollutants such as moisture and dust, and protect the electronic components inside new energy vehicles from damage. For example, in key electronic components such as engine control modules and ignition coils, the silicone encapsulation process can provide a stable operating interface to ensure their normal operation.
3. Global Market Insights: Future Opportunities for Silicone keypads and Silicone Products
- European and American markets : Brands such as Tesla and Volkswagen are accelerating their layout of customized demand for silicone buttons. The sales of new energy vehicles in Europe are expected to exceed 5 million in 2025, and the demand for silicone products will surge.
- Asian market : BYD and CATL promote the application of silicone materials in battery thermal management, and the Southeast Asian market has become a new growth point .
- Emerging markets : The demand for economical new energy vehicles in countries such as India and Brazil has promoted the popularization of silicone buttons in mid- and low-end models.
The "Silicone Code" to Seize the High Point of Technology in 2025
When the industry focuses on solid-state batteries and AI cockpits, silicone buttons and silicone products are deeply involved in this transformation as "hidden champions". From electric pickup trucks in the Sahara to smart heavy trucks in the Norwegian fjords, weather-resistant, lightweight, and highly integrated silicone solutions will become the core benchmark for defining the next generation of new energy vehicles.
