Rheological and physico-mechanical properties of hybrid carbon black/palm kernel shell biochar (CB/PKSBC) filled carboxylated nitrile butadiene rubber (XNBR) composites / Zafirah Zainal Abidin

Palm oil related industry has been developing and blooming very well nowadays which would lead to abundance of palm oil waste. These palm oil waste especially palm kernel shell (PKS) can be turned into palm kernel shell biochar (PKSBc) and used as a natural filler in rubber composites. PKSBc has the...
