Huntsman: Composite Resin Systems for Hydrogen Pressure Vessels

Best Composite Resin Systems for Hydrogen Pressure Vessels

Huntsman Araldite® composite resin systems enhance the performance of hydrogen tanks by providing:
High pressurization cycle performance
Explosion resistance & crack prevention
Improved impact & fatigue resistance
Resistance to extreme temperatures, humidity, and environmental exposure

Recommended Resin Systems:

  1. ARALDITE® LY 1135-1 A / ARADUR® 917-1 / ACCELERATOR 960-1

    • Best for wet filament winding
    • High mechanical, thermal, and dynamic properties
    • Tg: 132-138°C, 56-62h service life at 23°C
  2. ARALDITE® LY 1564 / ARADUR® 917-1 / ACCELERATOR 960-1

    • Suitable for wet filament winding
    • Longer processing time (80-90h service life at 23°C)
    • Tg: 122-130°C
  3. ARALDITE® LY 3708 / ARADUR® 1571 / ACCELERATOR 1575

    • Designed for prepreg winding with high filament count
    • Fast curing, high pressure resistance
    • Tg: 120-130°C, fracture toughness 1.5-1.6 MPa-m½

Choosing the right resin system and production method is crucial for cost-effective, safe, and efficient hydrogen pressure tanks. Huntsman’s Araldite® resins offer optimal performance, durability, and safety for high-pressure hydrogen storage solutions.
