MOOC - Rubber Technologist - Basic Level
Filler Technology
This unit will go into detail on rubber reinforcement by filler technology. Fillers can be non-,semi- and highly reinforcing. For high performance applications rubber is fully filled with highly reinforcing carbon black or silica (silane). These filler are available in in various species which result in different in-rubber compound properties.
Silica & Silane:
This element will elaborate on precipitated silica production and silica & silane reinforcement
