Summary:

Nanofillers are of great significance for the rubber industry since they provide higher strength, resistance to tearing and abrasion, and improved thermal and electrical conductivity in many applications such as automobile components and oil field applications. Carbon nanotubes, fullerenes, and nanoclay are novel reinforcing fillers for potential use in rubber products. These fillers were compounded with highly saturated nitrile rubber (HNBR) and nitrile rubber (NBR) using a Banbury mixer. The mechanical and rheological properties were studied using standard mechanical tests such as tensile and abrasion tests, and a rubber process analyzer for dynamic rheological properties.
