Best in Class
Aquivion®'s short side chain (SSC) makes it possible to achieve either better mechanical properties at the same IEC (ion-exchange capacity) or a higher IEC with the same mechanical properties as long side chain polymers (LSC).
- Very high concentration of functional groups for strong proton (or Na+, K+, Li+) conductivity
- High softening point for high-temperature operation well above 80°C
- Strong water retention for better low-humidity fuel cell operation
Ionomers side chain length comparison
Comparison of short side chain (SSC) and long side chain (LSC) ionomers
The material’s distinctive Short Side Chain (SSC) ionomer imparts higher crystallinity, improved mechanical properties (heat of fusion j/g), and better proton conductivity (lower EW equivalent weight).
Comparing Aquivion® SSC, versus LSC structure, SSC has a higher crystallinity at the same EW.
