High-Temperature Composite Resin
NEXIMID® R331 is an addition-curable, fully imidized oligoimide resin designed for high-temperature composite applications.
It combines low melt viscosity with a wide processing window, enabling efficient manufacturing and excellent final material performance.
Optimized for Efficient Composite Manufacturing
With its low viscosity and long processing stability, NEXIMID® R331 is ideally suited for cost-efficient manufacturing processes such as Resin Transfer Molding (RTM).
The material enables reliable impregnation and reduced scrap rates, particularly in out-of-autoclave production.
Key Performance Benefits
- Low melt viscosity (~500 mPas at 280°C)
- Wide processing window and long stability
- Easy processing in RTM systems
- High glass transition temperature (Tg > 330°C)
- Excellent thermal and mechanical performance
Designed for High-Temperature Performance
The resin is formulated using NEXIMID® crosslinkers and monomers to deliver exceptional thermal stability and mechanical strength.
This enables the production of composites suitable for demanding environments where high temperature resistance and durability are critical.
Typical Applications
- Carbon fiber reinforced composites
- Aerospace structures
- High-temperature industrial components
- Lightweight structural parts
- Out-of-autoclave composite manufacturing
Processing Capabilities
