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

1. 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.
2. 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
