Properties of vulcanized rubber nanocomposites filled with nanokaolin and precipitated silica

One kind of nanokaolin (NK) powder with 20–50 nm average thickness, 300–500 nm average diameter, and 32 m2/g specific surface area, has been introduced into four types of rubber, specifically styrene butadiene rubber (SBR), natural rubber (NR), butadiene rubber (BR) and ethylene–propylene diene methylene (EPDM). Their reinforcing effects were evaluated by comparisons with those from precipitated silica (PS). The curability, mechanical...
