LE-9265/LH-9265: High Tg UL 94 V-0 Epoxy for HV Insulators & Bushings | APG/Vacuum Casting
LE-9265/LH-9265 is a modified cycloaliphatic epoxy resin system engineered for high-voltage insulators, bushings, and contact boxes (12–40.5 kV). Combining UL 94 V-0 flame resistance, extreme weather durability, and high thermal stability (Tg >150°C), this unfilled liquid resin delivers void-free insulation for outdoor power infrastructure. Compatible with Automatic Pressure Gelation (APG) and vacuum casting, it ensures superior dielectric strength (>18 kV/mm) and CTI >600 V for decades of reliable service.
| Property | Advantage |
|---|---|
| Weather Resistance | Withstands UV, humidity, and pollution – ideal for outdoor bushings. |
| Flame Safety | UL 94 V-0 certified – prevents fire propagation in electrical faults. |
| Thermal Performance | High Tg (>150°C) + thermal shock resistance – stable under load cycles. |
| Electrical Integrity | CTI >600 V, high dielectric strength – resists tracking/arcing. |
| Processing Flexibility | APG or vacuum casting – integrates with existing production lines. |
| Long-Term Reliability | Resists cracking, hydrolysis, and chemical corrosion. |
