| Dielectric Constant | 3.0-4.0 (50Hz) |
| Flammability | V1 (UL94) |
The LW-8229A/LW-8229B is a pre-mixed, filler-loaded epoxy system designed for medium/high-voltage insulation (10-35kV). Combining modified BPA epoxy (LW-8229A) and anhydride hardener (LW-8229B) with integrated fillers, it delivers superior crack resistance, V1 flammability rating (UL94), and H-class thermal endurance (180°C). Optimized for vacuum casting and APG processes in transformers, CTs, and terminal posts.
| Feature | Advantage |
|---|---|
| Pre-Mixed Fillers | Simplified processing, consistent dispersion |
| V1 Flammability Rating | Enhanced fire safety for critical electrical components |
| Thermal Class H (IEC 60085) | Stable performance up to 180°C |
| APG & Vacuum Casting Ready | Flexible production integration |
| High Arc Resistance | 181-198 sec (IEC 61621) |
| Low Water Absorption | 0.10-0.20% (23°C/10d) |
| Dual-Process Compatibility | Adapts to APG or vacuum workflows |
Ideal for sealed electrical insulation:
