Abstract

This paper presents the results from investigations into the differences in the rotational moulding and mechanical properties between pigmented polyethylene powder and micropellets. Both high shear and low shear pigment blending methods were examined, as were a range of pigment addition levels. This was followed by a series of mechanical and analytical tests on the rotomoulded articles to determine properties. Whilst micropellets tended to produce a different surface porosity than powder, few bubbles were evident within the wall thickness for both high shear and low shear blending. For high shear blending, with pigment addition levels up to 0.05%, similar impact properties were noticed for both powder and micropellets. Low shear blending resulted in more inconsistent impact values. There were also more visual inconsistencies in articles produced from powder.
