Description

LE-9265/LH-9265: High Tg UL 94 V-0 Epoxy for HV Insulators & Bushings | APG/Vacuum Casting

Product Overview

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.

Key Features & Benefits

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.

Applications

  • 12–40.5 kV switchgear: Contact boxes, cable terminations

  • Outdoor bushings & insulators

  • Transformer bushings and surge arresters

  • Railway/utility power distribution insulation

Technical Specifications

Component Part Ratio (pbw) Form
Epoxy Resin LE-9265 100 Liquid (unfilled)
Anhydride Hardener LH-9265 100 Liquid
Silica Filler WY-12X 250–270 Optional
Color Paste LC Series 3 Optional

Cured Properties:

  • Glass Transition Temp (Tg): >150°C

  • Dielectric Strength: >18 kV/mm

  • Comparative Tracking Index (CTI): >600 V

  • UL 94 Rating: V-0

  • Thermal Shock Resistance: >1,000 cycles (-40°C to +125°C)

Processing Methods

  1. Automatic Pressure Gelation (APG):

    • Fast, low-waste production for high-volume insulator molding.

  2. Vacuum Gravity Casting:

    • Bubble-free encapsulation for complex bushing geometries.

Why Choose This System?

  • Weatherproof: Cycloaliphatic base resists yellowing/erosion in harsh environments.

  • Safety Compliance: Meets UL 94 V-0, IEC 60137, and ASTM D2303 standards.

  • Customizable: Adjust filler ratios (WY-12X) for viscosity/mechanical needs.

  • Zero Voids: Ensures partial discharge-free insulation for HV applications
