Abstract

This paper studies the effect of pigment concentration and pigmentation blending methods on the impact properties, crystallimity and morphology of rotationally moulded polyethylene parts. Hot stage microscopy, differential scanning calorimetry and dynamic mechanical thermal analysis techniques were used. It was observed that the pigmentation blending method used and level of pigmentation had only limited effect on the extent of crystallinity. The reduction in impact performance for turboblended pigmented samples was due to the relatively poor distributive and dispersive mixing of the pigment within the polymer matrix.
