Unlike many smaller rotational molders, Agri-Plastics Custom Rotomolding has sufficient volumes of material to allow us to commit to the much superior method of melt compounding our coloured polyethylene. When dry mixing pigments into polyethylene, the pigment acts as a foreign body, significantly decreasing the physical properties of the material. Melt compounding creates a more homogeneous blend and allows physical properties, such as impact resistance, to be far greater. This is very important to most OEM customers, as well as for any product that might receive impacts through normal use.
