Product Description

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

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.

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

Components

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

Automatic Pressure Gelation (APG): Fast, low-waste production for high-volume insulator molding
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
