Six different high-impact polystyrene (HIPS) and polystyrene-b-polybutadiene-b-polystyrene block copolymers (SBS) (thermoplastic elastomers, Kraton D1184) blends were mixed with varying HIPS to SBS ratios. The structure of the blends were investigated by scanning electron microscopy and compared to mechanical and tribological properties as a function of SBS content. Furthermore, the elastic modulus, yield and tensile strengths, % elongation, Izod impact resistance, hardness, Vicat softening point, heat deflection temperature, density, melt flow index and wear rate values of the polymer blends for all the HIPS to SBS ratios were determined. The addition of SBS to HIPS changed the friction coefficient and the wear rate of the blends significantly. Blends with higher SBS content showed higher wear rate than pure HIPS under dry sliding.
