CW229 HW229 Huntsman Araldite Epoxy System for Electrical Insulation Casting Material
Huntsman Araldite CW229 HW229 Epoxy System Electrical Insulation Casting Material
Araldite CW 229 CI / HW 229 CI Product Introduction
Basic Product Properties
Key Features:
- Type: Two-part epoxy system (Resin/Hardener)
- Mix Ratio: 100:100 by weight
- Curing Method: Thermal curing (70–160°C)
- Filler Content: ~55% (Resin), ~62% (Hardener)
- Operating Temperature: Up to 200°C
Product Overview
Key Advantages:
Flexibility: Maintain flexibility even after curing (elongation at break 1.3-1.5%).
Thermal Stability: Glass transition temperature (Tg) of 110-120 ° C (DSC test).
Process Efficiency: Long applicable period (≤ 2-3 days at 25 ℃), supporting large-scale production
Special Properties
- Mechanical Performance:The cured material exhibits high tensile strength (75-85 N/mm ²) and bending strength (110-130 N/mm ²), suitable for scenarios subjected to mechanical stress. Its linear thermal expansion coefficient (30-32 × 10 ⁻⁶ K ⁻¹) is close to that of metals, reducing the risk of thermal stress cracking.
- Electrical Properties: High volume resistivity (>1E14 Ω· cm at 23 ° C), stable dielectric constant (~4.0 at 50Hz), suitable for high-voltage insulation applications
Applications
Typical Uses:
- Dry-type transformer coils
- SF₆-insulated switchgear components
- High-voltage bushings and insulators
