Recently reduction of zinc oxide level in rubber compounds has become an important issue because of concern over levels of zinc in Europe's waterways and harmful effect of soluble zinc compounds to aquatic organisms.
The aim of our work was to evaluate possibility to reduce zinc oxide amount in isoprene rubber (IR) compound by using high surface area zinc oxide obtained by hydrothermal method. In the second stage of our work possibility of utilization of zinc oxide coated with poly(oxyethylene)glycol in rubber compounds was investigated. The presence of polyglycol that is an interphase transfer catalyst improved dispersion of zinc oxide in rubber compounds and increased vulcanization rate. The application of zinc oxide coated with polyglicol enables to reduce its amount in IR compounds to 2 phr without deteriorating mechanical propertis of vulcanizates.
