Improving the friction and abrasion properties of nitrile rubber hybrid with hollow glass beads

This paper presents the results of an investigation into the effects of hollow glass beads (HGB) fillers on the tribological behaviors of nitrile rubber (NBR). Properties like tensile strength, fracture energy and glass transition temperature were studied. The tribological tests show that the HGB hybrid into rubber matrix can reduce the friction coefficient of NBR and enhance its anti-wear ability. The fracture energy and interfacial strength investigation indicated that the HGB filler have a good interfacial action and can enhance the anti-wear behaviors of original rubber. Furthermore, the greater apparent effective aspect ratio of filler could improve the interfacial strength and benefit to the enhancement of anti-wear behaviors of polymer.
