The effect of powder characteristics on the rotational molding and sintering performance was investigated. The six LLDPE resins showed comparable rheological and thermal properties. Resins with poor powder quality produced parts with lower density and impact strength. The irregularities in shape due to grinding influenced the sintering results. To eliminate this effect on the sintering experiments cylinders were used. Variations in the sintering results, however, were also observed when using cylinders.
