Shenzhen Potting Compound Factory 1:1 Custom OEM Thermal Conductive Potting Compound for EV BMS Battery

HANAST HN-8806 A/B Custom OEM 1:1 Thermal Conductive Silicone Potting Compound for EV BMS Battery

HN-8806 A/B is a custom OEM two-component 1:1 RTV silicone potting compound engineered for EV Battery Management System (BMS) encapsulation. Produced by our Shenzhen potting compound factory in Guangdong, China, it cures into a grey elastomer that delivers thermal management and electrical protection for automotive-grade power electronics, with OEM/ODM customization of viscosity, hardness and thermal conductivity.

Key Features

• Thermal conductivity of 0.76 W/m·K or more for heat dissipation in BMS and OBC modules
• UL94 V-0 flame retardancy for EV safety compliance
• High dielectric strength of 25-30 kV/mm for high-voltage battery systems
• Wide operating temperature range from -50°C to 250°C for automotive environments
• 1:1 mix ratio by weight for simplified metering and automated production
• Low shrinkage and non-corrosive, protecting sensitive BMS components
• Deep-section curing with no exotherm and no stress on power semiconductors
• Custom OEM/ODM formulation of viscosity, hardness and thermal conductivity
• RoHS and REACH compliant for global automotive supply chains
• Supplied as non-dangerous goods with SDS available; 6 months shelf life

Typical Applications

• EV battery BMS: protects battery management modules from vibration, moisture and thermal stress
• Onboard charger (OBC): high-voltage power modules requiring thermal management and insulation
• Automotive ECU and DC-DC converters in harsh under-hood environments
• Power modules and circuit boards with heat dissipation requirements
• Sensors, controllers and general electronic appliances requiring insulation and moisture resistance
• Applications requiring deep-section curing and low shrinkage
