LE-9216F/LH-9216F: UL 94 V-0 Epoxy System for Flame-Retardant MV Switchgear Insulation

BPA Epoxy Resin + Anhydride Hardener for Critical Fire Safety

Product Overview

LE-9216F epoxy resin and LH-9216F hardener deliver UL 94 V-0 certified flame retardancy for MV switchgear, transformers, and insulators. This halogen-free system creates self-extinguishing encapsulation (extinguishes in <3 seconds), meeting IEC 61439 safety standards while maintaining exceptional dielectric strength (>25kV/mm) and arc resistance.

Key Features & Compliance

Property Performance
Fire Safety UL 94 V-0 • Low smoke density • Char-forming barrier
Electrical CTI >600V • Arc resistance >180 sec • Volume resistivity >1E14 Ω·cm
Environmental Hydrolytic stability • Chemical resistance to cleaning agents
Processing Low viscosity • Void-free impregnation • Room-temp liquid

Applications

  • MV Switchgear: Busbar encapsulation, compartment insulation

  • Dry-Type Transformers (10-36kV)

  • Circuit Breaker Insulation

  • High-Voltage Insulators & Bushings

Processing Flexibility

Method Advantage
Vacuum Gravity Casting Eliminates bubbles in complex geometries
Automatic Pressure Gelation (APG) 50% faster cycle times • Precision molding
Compatible with existing manufacturing workflows

Optimized Formulation

Component Material Ratio (pbw)
Epoxy Resin LE-9216F (BPA Type) 100
Hardener LH-9216F (Anhydride) 100
Filler Silica Powder 300-370
Colorant LC Series Paste 3

Certified Performance Data

Category Parameter Value
Fire Safety UL 94 Rating V-0 (3.0mm thickness)
Electrical Dielectric Strength 25-28 kV/mm
Thermal Glass Transition Temp (T<sub>g</sub>) 135°C
Mechanical Flexural Strength 110 MPa

Why Choose LE-9216F/LH-9216F?

  • Risk Mitigation: Prevents arc-fault propagation in switchgear

  • Zero Compromise: Maintains electrical properties while achieving V-0

  • Durability: Withstands thermal cycling (-40°C to +155°C)

  • Efficiency: Low exotherm curing reduces manufacturing energy

Engineered for critical infrastructure protection – Trusted for encapsulating medium-voltage components where fire safety and dielectric performance are non-negotiable.
