Difference between White Carbon Black and Carbon Black in Application
carbon black | White carbon black | |
Main components | charcoal | Silicon oxide |
Formation mechanism
| It is thermally decomposed and agglomerated in a very short time | During sedimentation and subsequent ripening |
Physical surface | Graphite, semi crystalline | Indefinite structure |
Surface group | A small number of different groups | Large uniform distribution (- OH) |
Surface affinity | Hydrophobicity | Hydrophilic |
Effect on s vulcanization | Negligible | It has a considerable effect on crosslinking |
Conductivity characteristics | Moderate conductivity | insulator |
Carbon black: White carbon black:
Strong filler, rubber effect Weak filler, rubber effect
Weak filler, filler effect Strong filling, filling effect
