The properties of CR filled with the two types of CF varying from 0 to 25 phr have been studied in detail. The results show that CF has great influences on the properties of CR. With the increase of CF added, the Shore A hardness, modulus at 300% and tear strength all increase, while the tensile strength decreases. Especially, the filler CF makes CR have excellent anti-aging properties, and the mechanical proper- ties of CR with different content of CF greatly increase in heat aging box for 72 h at 100˚C.
