Silicone Materials for NEVs are high-performance specialty adhesive materials independently developed for the three core systems of new energy vehicles: battery systems, motors, and electronic control systems.
Using high-purity silicone polymers as the base material, combined with high-activity thermally conductive fillers, environmentally friendly flame-retardant additives, reinforced performance systems, and specialized curing agents, these materials can form highly elastic and stable silicone rubber protective layers after room-temperature or heat curing.
The products combine multiple key functions, including excellent thermal conductivity, electrical insulation, wide-temperature resistance, flame retardancy, shock absorption, sealing, and waterproof protection. They play an important role in improving thermal management efficiency, ensuring high-voltage electrical safety, and enhancing the long-term operational stability of NEVs.
| Performance Dimension | Core Technical Indicators | Application Value in NEVs |
| High & Low Temperature Resistance | Stable long-term operating temperature: -60℃～200℃; Reliable performance under extreme conditions: -40℃～200℃ | Suitable for extremely cold and high-temperature operating environments worldwide. Maintains stable performance without cracking, sagging, or hardening during long-term use |
| Thermal Conductivity & Heat Dissipation | Thermal conductivity up to 5.0 W/m・K | Quickly transfers and dissipates heat to meet the thermal management requirements of battery, motor, and electronic control systems, reducing overheating risks |
| Flame Retardant Performance | Meets UL94 V-0 flame retardant standard | Helps slow down and prevent flame spread, reducing the risk of battery thermal runaway and improving overall vehicle safety |
| Electrical Insulation | High volume resistivity and high dielectric breakdown strength | Provides insulation protection for high-voltage systems, preventing leakage and short circuits while ensuring electrical safety |
| Aging & Weather Resistance | Excellent UV resistance, ozone resistance, and chemical corrosion resistance | Withstands harsh outdoor environments, extends service life, and supports full vehicle lifecycle requirements |
| Curing Adaptability | Flexible curing with low internal stress | Minimizes stress during curing, helping absorb thermal expansion and contraction while protecting precision electronic components |
| Bonding & Sealing Performance | Strong adhesion to metal, plastic, glass, and other substrates | Provides reliable waterproof, dustproof, and anti-corrosion sealing performance without debonding during long-term vibration |
Silicone Materials for NEVs are widely used across various protection and sealing applications from core electrical systems to vehicle body components, including:
● Power Battery Systems: Thermal management for battery modules (thermal grease / silicone pads), battery pack structural bonding and sealing, and thermal gap filling for battery cells
● Electronic Control Systems: Potting insulation and protective encapsulation for BMS, ECU, VCU, and other control units
● Electric Drive Systems: Thermal insulation, structural fixing, and sealing protection for motors, inverters, and onboard chargers (OBC)
● Charging Systems: Sealing, insulation, waterproofing, and dustproof protection for charging guns, charging stations, and battery swap interfaces
● High-Voltage Safety Systems: Insulation protection and sealing fixation for high-voltage wiring harnesses, connectors, and power distribution boxes
● Body & Sensing Systems: Waterproof sealing for vehicle bodies, sunroofs, and windows, as well as fixing and protection for automotive sensors and radar systems
| Comparison Dimension | Advantages of Our Silicone Materials for NEVs | Conventional Industry Standard |
| Thermal Conductivity Stability | Maintains stable thermal conductivity during long-term high-temperature operation for consistent heat dissipation | Thermal fillers tend to settle and age over time, causing reduced thermal performance |
| Curing Process Adaptability | Uniform curing with ultra-low internal stress, providing better protection for precision chips | Uneven curing and excessive stress may deform or damage sensitive electronic components |
| Cost Performance | Competitive overall procurement cost while maintaining high performance | Imported products are expensive, while low-cost alternatives often fail to meet technical standards |
| Supply Capacity | More than 40 years of silicone adhesive production experience with full in-house manufacturing, stable inventory, and reliable delivery | Smaller brands may face limited production capacity, while imported brands often have long lead times |
| Compliance Support | Complete documentation including SDS and MSDS for global market compliance | Many suppliers lack complete certifications and cannot support international procurement requirements |
