Tin dioxide, SnO nanoparticles combined with deproteinized natural rubber could be an effective electrical insulator that inherits its parents’ insulation and conductivity. The deproteinized natural rubber (DPNR) nanocomposites containing uncalcined SnO nanofillers at 0.5, 1.0, 3.0, and 7.0 phr were investigated for tensile and dielectric properties. The nanocomposites were prepared using a Haake internal mixer through a melt compounding method and vulcanized by a semi- EV system. Their properties were explored and compared with the DPNR vulcanizate. The highest tensile strength of about 28 MPa was obtained at 3.0 phr SnO loading. The elongation at break increases with the increase of nanofiller loading up to 3 phr and then decreases. With a rise in SnO , the dielectric constant decreased but increased once 7 phr SnO was added. The nanocomposites exhibited the minimum dielectric constant at the optimum SnO loading of 3.0 phr. Therefore, the SnO - reinforced DPNR nanocomposites are promising to be further explored for a stretchable electric insulator material.
