Effect of zinc oxide on dispersion and homogeneity of PTFE in NR/NBR rubber matrices / Noorzalila Muhammad Niza and Buvearasan Muniandy

The effect of zinc oxide (ZnO) on the dispersion and homogeneity of polytetrafluoroethylene (PTFE) in the blend of natural and nitrile rubber matrices (NR/NBR) has been investigated. The rubbers and additives were mixed on a two-roll mill and vulcanized by a steam-heated press. The findings from the...
