The Sigracet Carbon Fiber Paper 22 Series is intended to combine the required production robustness and the excellent performance properties. Stack developers and assemblers are benefiting from the following greatly improved characteristics:
- Greatly improved homogeneity inter-lot and intra-lot. The overall variability has been shown to be better than +/- 10% (2 sigma)
- Greatly improved surface flatness
- Greatly reduced occurrence of faulty spots on a roll
- Best performance under various operating conditions
Sigracet 22 BC replaces Sigracet 29 BC. The thickness, areal weight and in-plane permeability (IPP) of 22 BC are designed to be comparable to 29 BC.
