3.0 W/mK Thermally Conductive Silicone Potting Compound for Power Electronics Encapsulation

The HN-8830A/B is a high-performance, two-component addition-cure silicone potting compound engineered for demanding power electronics applications. With an industry-leading 3.0 W/m·K thermal conductivity, it efficiently dissipates heat from IGBT modules, power semiconductors, BMS circuits, and PCB assemblies, ensuring long-term reliability under extreme thermal cycling conditions.

Key Features & Advantages

• Superior Thermal Management: 3.0 W/m·K thermal conductivity achieved through high-density aluminum oxide and aluminum nitride filler packing, outperforming standard 1.0-2.0 W/mK potting compounds.
• IGBT Power Module Optimized: Specifically formulated for IGBT, MOSFET, and SiC power module encapsulation, preventing thermal runaway in high-power switching applications.
• UL94 V-0 Flame Retardancy: Self-extinguishing formulation meets the strictest fire safety requirements for EV battery systems, charging infrastructure, and industrial power supplies.
• Excellent Electrical Insulation: Dielectric strength ≥18 kV/mm provides reliable high-voltage isolation for BMS, traction inverters, and DC-DC converters.
• Wide Operating Temperature: Maintains stable mechanical and electrical properties from -40°C to +150°C, suitable for under-hood automotive and outdoor industrial environments.
• Low Viscosity & Self-Leveling: 11,000±2,000 mPa·s viscosity enables complete penetration into tight PCB gaps and complex IGBT module geometries without air entrapment.
• RoHS & REACH Compliant: Fully compliant with EU environmental regulations for global supply chain acceptance.
