Silicone Materials for New Energy Automobile are high-performance special adhesive materials independently developed for the core components of new energy vehicles, namely the three major systems: battery, motor and electronic control.
Formulated with high-purity silicone polymer as the base material, compounded with high-activity thermally conductive fillers, eco-friendly flame retardant additives, high-performance reinforcement systems and special curing agents, the materials can form highly elastic and stable silicone rubber protective layers after curing at room temperature or under heating conditions. Integrating multiple key properties including high thermal conductivity, superior electrical insulation, wide-temperature weather resistance, flame retardancy, shock resistance, sealing and waterproofing, they serve as core supporting materials to ensure thermal management efficiency, high-voltage electrical safety and long-term operational reliability of new energy vehicles.
| Performance Dimension | Core Technical Indicators | Vehicle Scenario Application Value |
| High & Low Temperature Resistance | Long-term stable operating temperature: -60℃～200℃; Normal operation under extreme conditions: -40℃～200℃ | Adapt to vehicle working conditions in extremely cold and hot regions worldwide. No cracking, sagging or hardening during long-term service, maintaining stable performance in complex environments |
| Thermal Conduction & Heat Dissipation | Maximum thermal conductivity up to 5.0 W/m・K | Rapid heat conduction and dissipation to meet thermal management needs of battery, motor and electronic control systems, preventing overheating and failure of core components |
| Flame Retardant Safety | Compliant with UL94 V-0 highest flame retardant grade | Effectively slow down and block combustion, greatly reduce the risk of battery thermal runaway propagation, and improve the passive safety level of the whole vehicle |
| Electrical Insulation | High volume resistivity and high breakdown voltage resistance | Isolate high-voltage circuits of new energy vehicles to prevent electric leakage and short circuits, and ensure full-cycle electrical safety of high-voltage systems |
| Aging & Weather Resistance | Excellent UV resistance, ozone resistance and chemical corrosion resistance | Resist erosion from harsh outdoor environments, extend service life and match the full life cycle demand of complete vehicles |
| Curing Adaptability | Low-stress flexible curing | Low internal stress during curing, offsetting deformation stress caused by thermal expansion and contraction of electronic components and avoiding damage to precision chips and sensitive parts |
| Bonding & Sealing | Strong adhesion to multiple substrates such as metal, plastic and glass | Outstanding water vapor barrier, dustproof and anti-corrosion performance; no debonding or falling off under long-term vehicle vibration for long-lasting sealing protection |
These dedicated Silicone Materials for New Energy Automobile fully cover full-scenario protection demands from the three core electrical systems to body accessories, with key application fields as follows:
● Power Battery System: Thermal conduction and heat dissipation for battery modules (thermal grease / silicone sheets), structural bonding & sealing of battery packs, and thermal filling for cell gaps
● Electronic Control System: Potting insulation and protection for BMS, ECU, VCU and other control units
● Electric Drive System: Thermal insulation, structural fixation and sealing protection for drive motors, inverters and on-board chargers (OBC)
● Charging System: Sealing, insulation, waterproof and dustproof protection for charging guns, charging piles and battery swap interfaces
● High-Voltage Safety System: Insulation protection and sealing fixation for high-voltage wiring harnesses, connectors and power distribution boxes
● Body & Sensing System: Waterproof sealing for vehicle bodies, sunroofs and windows; fixation and protection for automotive sensors and radars
| Comparison Dimension | Our Product Advantages | Conventional Industry Standard |
| Thermal Conductivity Stability | No obvious attenuation of thermal conductivity under long-term high-temperature operation for sustained and stable heat dissipation | Thermal conductive fillers are prone to settlement and aging after long-term use, leading to sharp decline in thermal performance |
| Curing Process Adaptability | Uniform curing with ultra-low internal stress, realizing non-destructive protection for precision chips | Uneven curing and high internal stress, easily causing deformation and damage to precision electronic components |
| Cost & Cost Performance | Optimized overall procurement cost with high cost performance under the same performance parameters | Imported products with equivalent performance are overpriced, while low-cost products fail to meet performance standards |
| Supply Capacity | Over 40 years of R&D and production experience in silicone adhesives, full in-house production capacity, sufficient spot inventory and stable delivery cycles | Small and medium-sized brands face insufficient production capacity; imported brands suffer from long lead times and high stockout risks |
| Compliance Support | Complete qualification documents such as SDS and MSDS to meet global market access requirements | Most manufacturers lack complete certifications and cannot support cross-border procurement compliance |
